E-Z Lok Threaded Inserts for metal are designed for repairing or reinforcing threaded holes in soft metals like aluminum, magnesium, and cast iron. The solid wall threaded inserts are designed to not back out or vibrate loose, and come in standard sizing so they can be installed with a screwdriver, bolt nut, etc. Adhesive sets immediately upon installation and is fastener-ready in 3-5 minutes. Inserts can be removed with a bolt extractor or by heating the insert to a temperature above 300°F, at which point the adhesive will release. Available in carbon or stainless steel and in thin, standard, or extra heavy wall, as well as screw locking and automotive designs.
