SCREWLOCKING INSERTS
These are our standard heavy wall inserts with thread locking adhesive applied to the internal threads providing a permanent screw-locking feature. The adhesive activates when a fastener
is threaded into the insert. Install these inserts with a screwdriver or drive tool, allowing 3-5 minutes for the external thread adhesive to set-up prior to threading in the fastener.
A bolt can be used for installation as long as you do not intend to remove it. Removing the bolt after installation destroys adhesive effectiveness.
