Shear Nuts

This specially designed nut works with any bolt of a comparable size. It has a standard hex head on one end that is attached to a smooth, conical shaped extension. When the nut is tightened that hex head actually shears off, leaving the conical shape on the bolt. This component acts as a stable nut, but is exceptionally difficult to remove.

Your application will have all of the stability and strength needed with the conical nut, but these fasteners do not present an easy removal method.

Torx Screws

One of the most popular lines of security screws, Torx is the brand that is often used for tamper proof applications. These fasteners have a specially formed recess that cannot be tightened or loosened using a standard bit. If one of these bits are used it will be obvious that the screw was tampered with. If your application requires tamper resistance, rather than a serious deterrent against tampering, these screws are a good option.

There are many different types of tamper resistant fasteners that come in a wide variety of designs and sizes. Many times a manufacturer will use a specific style (or two) of tamper resistant screw, if only to streamline the bits required for assembly. If they also need to provide a bit to their customers for at home assembly, it makes sense to use the same style of screw in various locations.

Oddly Shaped Nuts and Screws

One of the easiest ways to produce a tamper proof or tamper resistant fastener is by making the shape unique. Sometimes it is the nut that is oddly sized and unable to be tightened by regular means; other times it is the screw head that includes a strangely shaped recess. Both of these designs work very well.

They can easily be maneuvered with the right tool, but otherwise these fasteners will need to stay put. This set up provides an acceptable level of security for many different applications.

No matter what option is used, tamper proof fasteners add value to your project and can be utilized to protect your customer and your business.

Wood Lag Bolts

Although some contractors use carriage bolts to attach beams to the posts on a deck frame, many opt for the simpler wood lag bolt. These deck fasteners are actually more like a screw, since they have a pointed tip and do not necessarily need a nut. You’ll still need a washer sandwiched between the hex head and the wood in order to distribute the load properly.

Joist Hangers

These brackets are generally made from zinc plated steel and are used to attach the joists in your deck framing. They work to distribute the weight of the wood and are a much safer, secure way to put together the perpendicular pieces of lumber that form deck framing. Often the lumber is simply nailed into a joist hanger, although in some cases screws may be used. All the joist hangers are covered by the deck board and can only be viewed from underneath once the deck is completed.

Spacers

When ACQ lumber is used to construct a deck and aluminum railing is installed on the same deck, certain levels of protection need to be applied. Due to the chemicals used in ACQ wood treatment it cannot have direct contact with aluminum. If it does, the aluminum will not last long. Spacers need to be installed between the two materials in order to allow both the longevity they are known for.

Most aluminum railing packages will include these elements, but ask at the local building supply store if you cannot find them or contact a fastener distributor to see what they would recommend. This can be a problem when wood posts are used in conjunction with aluminum railing or aluminum railing posts are bolted onto the surface of a pressure treated wood deck.

Be sure that you are fully stocked up on all of the deck fasteners required to construct your project. From deck screws to wood lag bolts, joist hangers and aluminum railing spacers, there are many different common and uncommon fasteners used during construction.

There are three things you need to look for in quality deck screws that will let you know the fasteners are adequate. Material, length and head type are all key characteristics when shopping for these screws.

Which Material Is Best?

Although they cost more initially, you’ll never regret installing stainless steel deck screws in your backyard. Designed to last no matter what nature throws at it, stainless steel is the number one choice for any fasteners used outdoors. They look beautiful and shiny when left unfinished although many of the top manufacturers offer color coated heads to allow for a seamless finish.

General residential applications will do well with 305 (or 18/8) grade stainless steel, whereas marine locations and areas that have a high exposure to salt may need to go with 316 grade stainless.

Which Length Is Needed?

Most deck screws are available in lengths from 2″ to 4″, depending on the size of the screw. While you may find a use for the 2″ length, most deck builders and DIY enthusiasts are best to invest in a large quantity of 3″ long deck screws. These can be used to secure the deck boards down, as well as attach the fascia board, stair treads and railings. A #10 x 4″ screw may be useful in certain circumstances, but by and large the 3″ will do everything that you need.

Which Head is Best?

In order to avoid camming out most professionals use the square or Robertson head screws. Your screwdriver or bit “cams out” when it slips from the screw head, causing damage to the screw and quite possibly your tools. A square headed screw eliminates this problem, as does a torx head. Some manufacturers offer the torx head on their deck screws, but many stick with the traditionally preferred square head.

Your deck will look better when you have chosen deck screws in the right material, the proper length and the most efficient head. Invest in the best and you’re bound to be satisfied.

Why Flat Head Screws?

To provide a smooth surface for the most comfortable walking conditions and the best appearance, flat head screws are a must. They are countersunk into the deck board to provide that flush surface that’s so desired. Whether your deck is built from cedar, treated lumber or composite products, a flat head will create the finish you want.

Typically a deck screw is 2 1/2″ and that length is measured from the top of the head (which would be flush with the surface) to the tip of the screw. This is plenty long enough to secure the 1 to 2” deck boards that people are using today. Flat screws are generally available in Phillips, square or torx heads as well, so you can take your pick and grab a bit to get started on the installation.

Are They Necessary On the Framing?

Although round head wood screws are available, most people do not use them anywhere on a deck. You might use oval countersunk screws on the framing, railing and stairs although they do leave a slight mound. Only flat head countersunk screws are used on the deck board.

Other fasteners used in the framing include lag bolts and carriage bolts – both with the typical bolt heads (either round or hex). Because the framing is hidden for the most part the head of your fasteners is not as important, although for consistency and convenience the same type of driving method is often used. Whether you prefer a square or a torx head, keeping your bit in the power driver is much quicker than switching it out for each fastener.

In order to provide the smoothest, most attractive finish on your decking flat head screws are the only choice. Order them in stainless steel to provide a lifelong strength and resistant to corrosion as well. Then sit back and enjoy your beautiful outdoor living space.

Nails, screws, bolts and lags – decks run the gamut of different fasteners. Each area is held together with a certain type.

Footings and Framing

Depending on how the foundation of your deck is installed, there may be post saddles or pins used on the footings. In other situations a wooden post is bolted into a floating pier or post spike.

Bolts and lags are used in the framing. Often the ledger board is bolted into the house and the beams are lagged into those wooden posts. Different contractors use different deck fasteners depending on their personal preferences and the applicable building codes.

Deck Boards

Most often deck boards are attached using deck screws. This provides a better finish on the decking and with the right tools, is installed just as quickly as nails are.

Deck screws offer a better finish when they are epoxy or ceramic coated. This type of fastener allows for color matching and a smoother, better looking finish. If nails are used the surface will be marred by silver/grey marks and it will be much more difficult to remove damaged deck boards. These coatings also offer better corrosion resistance.

Railing and Stairs

Nails can be used in the stairs and on railing components, although this is still a common place for screws. Since deck boards are often used for the stairs, the same deck screws that were used on the deck surface are seen. Nails often fasten the stringers to the framing.

Railing pickets are screwed in, although much shorter screws are used. When tempered glass is used the framings may be nailed, but with aluminum pickets and component products, everything is fit together with screws.

All deck fasteners need to be corrosion resistant, whether that is through a plating or coating or due to the material itself. Stainless steel fasteners are ideal for outdoor projects like a deck and well worth the extra expense. For a dependable, long lasting finish choose deck fasteners with the highest levels of strength.

Stats for the Typical Deck Screw

Most often a deck screw will be 2 1/2″ long and either a #7, #8 or #10 in size. Every so often you’ll find the need for a #12 screw. And thinner deck board will require 1 5/8” lengths.

Screws for use on decks, fences and other outdoor structures are most often driven with a square (or Robertson) head, a Phillips head or a Torx head. Each of these has advantages over the other with regards to commonly used tools, less wear or stripping and speed of installation.

Materials and Coatings for Decking Screws

The material you choose for your deck screws needs to be compatible with the material of your deck board. For instance, composite decking needs to be installed using composite deck screws – a good choice both for strength and looks. Wood decking, on the other hand, is best installed using stainless steel composite or hardware that has been tested for use with ACQ, the common chemical treatment for softwood lumber.

Composite deck screws can also be stainless steel, but are available in colors designed to compliment and match the colored deck boards, trim and railing components. Ceramic coated screws can be used with both pressure treated lumber and composite decking. A more widely seen option is epoxy coated deck screws. These are available in a wide variety of colors and the resin coating will not chip off as easily during installation (as can be the case with ceramic).

When building with ACQ treated lumber, always be sure that the fastener material is compatible with that chemical concoction. Check with the fastener manufacturer or read through the MSDS for ACQ or the screws themselves to find out which materials to avoid and which are safe.

Unless you opt for an invisible fastener system, the surface of your deck will be dotted with screws. Be sure to take the time and choose the best possible deck screws for your application. The final product will be worth it.

There are three common methods of getting these vital materials to your job site.

Building Supply Store Pick Up

Either you can drive down to the local building supply store or send one of the guys. More often than not, unless you’re looking for a small amount of a standard fastener, these big box stores won’t have what you need on the shelf. But because they’re handy, many contractors try them first.

Specialty deck fasteners are not on the inventory of popular building supply stores. And most of the time you can count on very little help from the employees (sorry guys, but you usually haven’t been trained in the ins and outs of fasteners and you probably don’t get paid enough to bother finding out for yourself).

If the product is in stock, great – this method is fast and efficient. If however, the big box building store doesn’t have the fasteners that you need, they’ll offer to put in a special order. The catch is that order will take an enormous amount of time and paperwork to get moving.

The verdict? A trip to the building store is not the best plan.

Fastener Rep Comes to You

Maybe you’re one of the lucky ones. Maybe the fastener rep drives by your jobsite every day and stops in with a current catalogue and price list. If this is the case, a rep should be able to answer your questions, fill you in on industry innovations and generally give you enough service to get the sale.

Let’s be realistic though – this isn’t usually how it works. Generally you’ll call the distributor’s office and set a time for the rep to come visit. They might be able to make it fast, but usually we’re talking at least a few days until they can get to you. Once they do make it, you might be able to put in an order on the spot and expect delivery within a few days. But if they don’t have the capabilities to do on the road ordering, you’ll be waiting until they get back to the office for the order to go in.

It’s bound to be an accurate order and the rep can troubleshoot any problems you’re having. They can show you the newest deck fasteners on the market and offer tips on ordering levels. But unless they’re on site within a few hours, there is still a better way to order deck fasteners.

Shop for Deck Fasteners Online

It’s true. The fastest and most accurate way to find the deck fasteners you need is online. There you can browse through a selection of specialty fasteners that are in stock and ready to ship. You can find information about the products, as well as tips and advice if you need it.

Perfect for the pros, online fastener distributors are the best place for builders just starting out as well. Buy one box or buy in bulk – it’s always convenient and always fast. Freight will add a little to the overall cost, but no more than you’ll pay ordering through the rep.

Look for an online retailer that specializes in fasteners, as opposed to those who offer everything under the sun. Then you can expect specialized service and knowledgeable help if and when you need it. Wondering whether stainless steel is worth the cost? Ask. Thinking about the benefits of specialty bits? Ask about that, too. Help is only a phone call or an email away.

When you need deck fasteners fast there’s only one place that delivers the selection, speed and knowledge necessary. Find on online fastener distributor and get ordering. Then get back to work.

You know you want it.  A place to lounge in the sun, host an outdoor summer bash or simply sit and catch your breath is just what you need.  All of that can be waiting outside the patio door if you tackled the plan to build a wood deck.

It can’t be too difficult, right?  With the right tools, a few afternoons of work and at least one extra set of hands it won’t be.  Your brand new, well built deck will sit proudly in your yard waiting for the kick off BBQ to start.

Building a deck is simple with only 4 basic steps:
•    Posts
•    Framing
•    Decking
•    Railing and other features

Don’t get too excited.  Within those four steps are a list of tiny, baby steps and big hurdles to get over.  Sounds like a challenge and DIY folks are always up for a challenge.

Throw a Post Digging Party

This Dingo with auger bit attached is the quick and easy way to dig post holes - well worth the rental fee.

Here’s where you can stretch those muscles and get involved in some hard labor.  Mark your post holes ahead of time with paint or stakes and string.  Also, give the local utilities a call to locate the phone, cable, gas and electrical lines underground.  Stay safe (and keep the cable TV on).

Depending on your grade and the deck’s height off the ground, you may need to excavate or level the grade.  Do what you need to do and remember that treated wood can be safely sunk in the ground.

Get the tape measure to the bottom of your 48" deep hole.

Dig your post holes about 48” deep and bell out the bottom for more stability and protection against frost heaving.

You can either extend 4×4 or 6×6 posts out of the ground and attach directly to the frame or pour a concrete pier (that’s essentially a hole filled with concrete and providing a flat surface on top).  Each method requires different hardware.

For extended posts you’ll need a 3/8” x 3 1/2” wood lag to attach the framing.  Use an impact driver to get the lag in with speed and accuracy.  Carriage bolts (3/8” x 7”) are another possibility and work well with wood.  Pre-drill your hole and set the nut tight to keep it all firm and strong.

With concrete piers you’ll need to bolt a post saddle into the concrete and attach a 4×4 with lags or carriage bolts to the saddle.

Benefits and drawbacks of either method?

Piers and saddles are good for the DIY crowd and you can get away with shorter 4×4’s or 6×6’s.  Don’t skimp on the hole depth or you’ll end up with a crooked deck come spring.

Put the post against your string line and fill the hole with concrete.

Extended 4×4 or 6×6 posts are simple to install in the hole with poured concrete around them.  Make sure you let the concrete set properly and use a string line to get the posts in the right locations.  Don’t forget to get that level and check the posts.

Mix the concrete in a wheelbarrow or rent a cement mixer for larger jobs.  This is grunt work, so draw straws.  For fast simple and fast results use quick setting concrete or a specialty fence/deck post mix.  You’ll need access to a nearby hose as well.

Fasteners should be 18-8 stainless steel although some contractors use hot dipped galvanized to cut costs.  In coastal marine environments, opt for 316 stainless for your best protection against the elements.

Step 2?  Framing is next up and coming in our next article. But have a drink and rest… those posts need to set so they’re ready to support the rest of the deck.
