FastenMaster is proud to introduce the newest addition to our LOK Line family of structural wood screws – FlatLOK!

FlatLOK is a multi-purpose structural wood-to-wood fastener that is a great alternative to using nails and through bolts when attaching multi-ply LVL, dimensional beams and girder trusses. It requires no predrilling, allowing your pro customers to save time and money and the flat head sits flush, allowing for easy application of 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 TORX ttap drive system 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.
