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, Trus 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.
- No predrilling! Faster and easier than through bolts
- Higher side load capacity with fewer fasteners saves time and labor
- Correct thread length for engineered lumber–No board jacking
- Prevents gapping or cupping between plies which can occur in nailed applications
- Winged point, modified thread design and anti-friction coating combine to significantly reduce installation torque
TrussLOK® is a code-compliant way to connect multiple plies of engineered lumber. View an application video in our Ask The FastenMaster Section or download our technical bulletins in the Code Approvals section.
