BX (50) 3-1/2" FLATLOK ENGINEERED WOOD FASTENER

FastenMaster FlatLOK is a multi-purpose structural wood-to-wood fastener that is an alternative fastening method to using nails and through bolts when attaching multi-ply LVL, dimensional beams and girder trusses. FlatLOK is easy-to-use because it requires no predrilling, thereby saving time and money. The flat head sits flush, allowing for easy application of drywall or trim. In addition, FlatLOK is approved for single-sided installation making the job easier to complete both at ground level or for elevated applications. FastenMaster FlatLOK wood screw features TORX(R) ttap(R) 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. FlatLOK is tested and supported by engineering data that conforms to the most current ICC standards. It is also approved for use in ACQ or treated lumber. FlatLOK should be installed using an impact driver or high torque 1/2" variable speed drill (minimum 18V if cordless). No predrilling is required when properly installed. Bring fastener flush with wood surface, do not overdrive. LVL Beams: Refer to FastenMaster's online technical bulletins and engineered wood manufacturer's technical information for complete load and engineering requirements. For applications other than those listed above, a Professional Engineer (PE) may be consulted to determine proper connection design.
