Description

Product Overview

E-Z LOK Threaded Inserts are solid, high-strength carbon steel components designed for repairing or reinforcing damaged threads in soft metals. Made from durable 12L14 carbon steel, these inserts offer superior holding power and self-locking capabilities to prevent loosening under stress. Ideal for aluminum, magnesium, cast iron, and other non-ferrous materials, they are engineered for industrial, mechanical, and DIY applications where thread integrity is critical. Each insert features internal 5/16-18 threads and external 1/2-13 threading for compatibility with standard fasteners.

Usage

These inserts are commonly used in manufacturing, automotive repair, machinery maintenance, and home projects where threaded holes have become stripped or damaged. They’re especially useful for reinforcing tapped holes in aluminum frames, cast iron engine blocks, magnesium housings, and other soft metals that cannot withstand standard tapping without deformation. Installation is straightforward: drill a hole with a standard bit, tap it with a standard tap, then turn the insert into place using a screwdriver, bolt, or E-Z LOK drive tool.
