E-Z Lok Externally Threaded Insert, 303 Stainless Steel, 3/8"-16 Internal Threads, 9/16"-12 External Threads, 0.515" Length, Made in US (Pack of 5);

E-Z LOK threaded inserts for metal provide an easy to use solution for repairing or reinforcing threaded holes in metal. Ideal for use in metals like aluminum and cast iron, E-Z LOK threaded inserts are screw machined out of solid steel for greater strength and superior pull out resistance. Standard external threads permit the use of standard drills and taps for installation. Once the hole is prepared, E-Z LOKs are threaded into the hole like an ordinary fastener using a screwdriver, bolt and jam nut, or optional E-Z LOK drive tool. E-Z LOKs are self locking and will not back out or vibrate loose. A preapplied adhesive activates upon installation and bonds to virtually all metals. Fastener-ready in minutes, the adhesive seals against liquids and gases to pressures of 6,000 psi. when fully cured (72 hours).
