There is a wide variety of Fasteners needed for deck construction. From joist hangers to carriage bolts, lags, nails and screws, standard fasteners make up around 2 to 5 percent of the overall material cost on the average deck. If you choose to go with hassle free 18-8 stainless steel hardware that percentage will increase. It’s important to choose your deck screws wisely since this is the Fastener you will see every time you walk out onto the deck surface. For Deck Screws, Hex Bolts, Nuts and Bolts or other Fasteners try a Fastener Distributor.

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.
