E-z Lok 500-6 Thread Insert Hand Installation Tool

Product Description

The E-Z LOK 500-6 is a hand installation tool designed for driving threaded inserts into pre-tapped holes without the need for power tools. Built from steel, it provides the durability needed for repeated use in shop or field conditions. This tool accommodates maximum thread sizes of 7/16-14, 7/16-20, and M12 x 1.75, covering both UNS and metric thread standards in a single tool. It is a direct-drive, manual tool suited for machinists, maintenance technicians, and assembly professionals working with threaded insert fasteners across a range of materials and applications.

This installation tool is used wherever threaded inserts must be installed by hand into metal, wood, or composite substrates. Typical applications include repair of stripped threads in aluminum housings, steel fabrications, and structural assemblies. Its compatibility with both inch-series UNS threads and metric M12 threads makes it a practical addition to a general fastener toolkit in manufacturing, HVAC equipment assembly, plumbing fixture work, and maintenance operations where insert fasteners are a standard repair method.

Installation Notes

This tool is used by machinists, maintenance technicians, and assembly professionals performing threaded insert installations. Ensure the receiving hole is properly tapped and clean before driving the insert. Apply steady, controlled hand torque to seat the insert flush or to the specified depth without overdriving. No power source is required, but the operator should verify insert seating depth per the fastener specification for the application.
