FastenMaster FMTSL338B-250 TrussLOK Engineered Wood Fastener, 3-3/8 Inches, 250-Count
The TrussLOK engineered wood fastener is designed for joining multi-ply LVL, LSL, and PSL. This fastener was developed with direct input from a leader in engineered wood, Truss Joist. TrussLOK is faster, easier, and stronger than through-bolts and other structural self-drilling fasteners with similar diameters. And TrussLOK is approved for single-sided installation unlike nails and other screws of similar diameter that need to be installed from both sides. Each pack size of TrussLOK contains a free driver bit. TrussLOK fasteners are American made.
