Kit Fixing 3 Screws

Three-screw mechanism fastening kit, consisting of three threaded inserts with corresponding M4 countersunk head screws, all made of AISI 316 stainless steel. The inserts have internal M4 threading and feature an external fake thread to securely grip the wood. To install, simply drill a slightly smaller hole and then insert them using a hammer. Once secured, they will remain firmly in place without ever loosening.”
