E-Z LOK, a division of Tool Components, Inc., is a third-generation, family owned and operated business, founded in 1956.

E-Z LOK started with the creation of its proprietary solid wall threaded insert designed for use in soft metals like aluminum, magnesium, and cast iron.

The E-Z LOK design allows users to repair damaged or worn out threads without the need for special taps or installation tools. Over the years, E-Z LOK's line of threaded locking inserts expanded to include specialized products for plastic and wood, as well as E-Z Coil™ helical coil threaded inserts for metal.

Extensive inventories are maintained in four warehouses across the US, to meet your immediate needs as quickly and cost effectively as possible.

Our line of thread locking inserts is carried by every major national MRO distributor in the U.S., as well as by regional and local distributors across the country.
