FlatLOK is a multi-purpose structural wood screw that can be used for fastening multi-ply LVL and girder trusses. The flat head allows for easy finishing including drywall or trim. FlatLOK is approved for single-sided installation making the job easier to complete both at ground level or for elevated applications. The FlatLOK wood screw features a TORX® ttap® drive system that maximizes bit fit, reducing the potential for stripping. The stability button allows for maximum penetration into the fastener and a wobble-free drive. A free TORX ttap bit is included in every box.Length/Applications
