Square Drive Decking Screws

Square drive decking screws are screws that you can use to fasten wood and composite decks to main beams. The standard square drive decking screws are 305 or 316 stainless steel type 17-point bugle flat head screws. These stainless-steel square head decking screws resist corrosion, so they are a perfect fastener for outdoor decks, since they can withstand a variety of exterior stresses and weather conditions.

In addition to bugle-head decking screws, square drive decking screws may be truss-head or trim-head. The square drive helps eliminate stripping, which can be a problem when applying pressure to the screw with other types of drives. The type-17 point allows you to start fast and get the screw into the wood cleanly and easily, with coarse threads about 2/3 of the way up the shank to draw the decking into a tight seal with the substrate.

FMW Fasteners’ square drive decking screws are versatile enough that you can use them for all types of wood decking, including preservative-treated woods. You will usually need about 350 to fasten 100 square feet of decking, assuming 6-inch, nominal-width boards installed on 16-inch joists.
