Thread inserts are used to replace damaged inserts, repair threaded holes that have been stripped, or create a new join. We offer several types suited for use on metal, wood, and plastic. Whereas the coil tension on helical thread inserts securely hold the insert in place, keylocking thread inserts have locking keys that are driven down to lock the insert in place. Self-locking thread inserts have adhesive on both the external and internal threads to secure the insert in place and to prevent fasteners from backing out of the insert. Knife thread inserts, which are designed for use on hardwoods, have an external thread that slices into the wood and provides superior holding power. Press-fit thread inserts are designed to replace molded-in inserts and threads in plastic castings. We also stock rivet-nut thread inserts, self-tapping thread inserts, and hex-drive thread inserts.
