TrussLOK® is a code-compliant structural wood screw designed for joining multi-ply LVL, LSL and PSL. This fastener was developed with direct input from leaders in the engineered wood market. TrussLOK® is faster, easier and stronger than through-bolts and other structural self-drilling fasteners with similar diameters. It is approved for single-sided installation unlike nails and other screws of similar diameter that need to be installed from both sides. TrussLOK features a hex head drive system and each package contains a free driver bit.

The ICC-ES Evaluation Report demonstrates to the installer and code official that our LOK fasteners comply with the most current building codes. This report also provides the engineer with critical values needed to design safe installations. Reports from ICC-ES are the most recognized reports used by code officials across the U.S. This document can be shared with code officials, engineers, architects and specifiers who may have questions regarding proper use or code compliance of LOK fasteners.
FastenMaster technical bulletins are abridged versions of our TERs that demonstrate general guidelines and fastening patterns.
