Simpson Strong-Tie HCKWSNTL212S Deck Screw, #8 Thread, 2-1/2 in L, Flat Head, #3 Drive, 300 Stainless Steel

Strong-Drive® WSNTL Subfloor screws are ideal for fastening subfloor, sheathing, sill plate and stair tread applications using the Quik Drive® auto-feed screw driving system. With lateral shear, withdrawal and pull-though values that exceed those of 10d common nails, the holding power of WSNTL screws reduces the gaps between the joist and subfloor that cause floor squeaks. Installing WSNTL screws removes the need for gluing in diaphragm applications, eliminating the precise timing, labor and materials that the process requires. Using screws that can be backed out easily allows future access to floor cavities.
