E-Z Lok Externally Threaded Insert 303 Stainless Steel 1/4-20

Description

Product Overview

The E-Z Lok 303 externally threaded insert is engineered from premium 303 stainless steel, offering exceptional corrosion resistance and durability in demanding industrial environments. Each insert measures 0.280 inches in length and provides a #6-32 internal thread that mates seamlessly with standard machine screws, while the 1/4-20 external thread enables secure attachment to a variety of fasteners. Designed for soft metals such as aluminum, cast iron, and magnesium, the insert delivers reliable holding power without compromising the integrity of the base material.

Manufactured in the United States, this pack of five inserts meets rigorous quality standards, ensuring consistent performance across every unit. The solid steel construction eliminates the need for additional reinforcement components, simplifying inventory management for maintenance teams and OEMs alike. With a weight of just 0.16 ounces per insert, the product adds minimal mass while providing maximum thread strength.

Usage

These inserts are ideal for a broad range of applications where thread integrity is critical. In aerospace maintenance, they can be used to repair worn-out threads on aircraft brackets, extending service life and reducing downtime. In marine environments, the stainless steel composition resists saltwater corrosion, making the inserts suitable for boat deck fittings and marine hardware. Manufacturing facilities often employ them to reinforce assembly fixtures on production lines, ensuring that repeated fastening cycles do not degrade thread quality.

Installation is straightforward: drill a hole to the recommended diameter, tap the hole with a standard tap, and turn the insert into place using a screwdriver, bolt, or the dedicated E-Z LOK drive tool. No special equipment or proprietary tools are required, which reduces training time and operational costs. The self‑locking design provides a secure grip that resists vibration and loosening, making the inserts a dependable choice for both static and dynamic loads.
