302 Self Tapping Thread Inserts are recommended used in most applications. In some materials,they provide perfect specific a screw thread lock effect. They provide permanent wear-resistant threads in a wide range of materials, from tough to tap, high strength steels to brittle plastics.
The thread cutting action is performed by the cutting slots on the insert. By tapping its own thread, the self tapping insert eliminates the need for pre-tapped holes.
