M8 through bolts are used to securely fix TruGuard supports to concrete or masonry. Fixing requires an 8mm diameter hole to be drilled in the concrete or masonry where the support is to be positioned. The bolt should be inserted through the clearance hole in the support, then torques to hold the support firmly in place. If the concrete or masonry is of poor quality it is recommended that a chemical fixing is used.
We would further recommend the use of threadlocking adhesive (available separately) with M8 through bolts.
