E-z Lok 500-3 Thread Insert Hand Installation Tool

Product Description

The E-Z LOK 500-3 is a hand installation tool designed for driving threaded inserts into pre-drilled holes without power equipment. Built from steel, this insert tool works with 1/4-20, 1/4-28, and M6 x 1 thread sizes, covering both UNS and metric standards in a single tool. It is used across maintenance, repair, and fabrication applications wherever damaged or stripped threads need to be restored or reinforced in metal, plastic, or wood substrates. Machinists, maintenance technicians, and assembly professionals are the primary users.

This tool is suited for light-duty, hand-driven insert installation in bench work, field repair, and production assembly settings. It handles both fractional inch and metric thread sizes, making it practical for shops that work across mixed fastener standards. The 1/4-20 and 1/4-28 UNS sizes cover common inch-series fastener applications, while the M6 x 1 thread size addresses standard metric fastener work. It is sold as a single unit and is compatible with E-Z LOK threaded inserts in the specified thread sizes.

Compatibility

Installation Notes

Installation is performed by hand and does not require power equipment, making it appropriate for bench work or field repair. Ensure the host material is properly prepared with a correctly sized pilot hole before driving the insert. Follow the insert and substrate manufacturer guidelines for hole diameter and depth. No torque tools are required, but consistent hand pressure and proper alignment are important to seat the insert flush and straight.
