Pull-Out Resistant Screw-to-Expand Inserts for Plastic
Fins cut into the surrounding material for a more secure hold than knurled inserts. Press or hammer them into a drilled hole, then install a screw. The screw expands the insert and drives the fins into the surrounding plastic to keep it secure. Made from brass, they’re nonmagnetic, corrosion resistant, and electrically conductive.
