Occasionally we want to make sure a screw will not work loose or can’t be removed for security reasons. Here are a few options available to the average woodworker.
Non-removable screws are available with heads that can only be used to insert the screw. The reverse side of the socket on the head has been removed to prevent a screwdriver’s head from grabbing on anything.
Epoxy – Special two-part wood/metal epoxies are available that can be used in a pilot hole to firmly lock a screw in place.
Serrated Teeth – Special screws with barbed or serrated teeth are available to prevent a screw from backing out of a hole.
Strip the Head – After the screw is properly seated used a drill bit to remove the sockets from the screws head.
