E-Z LOK Threaded Insert for Metal 12L14 Carbon Steel Thread Inserts 5/8-11 Internal Threads, 7/8-9 External Threads, 1.125″ Length, Pack of 5

Description

Product Overview

E‑Z LOK Threaded Insert for Metal is engineered to deliver reliable, self‑locking performance in a wide range of soft metal applications. Constructed from 12L14 carbon steel, each insert features a 5/8‑11 internal thread that mates with standard fasteners and a 7/8‑9 external thread that engages the tapped hole in the workpiece. The 1.125‑inch length provides ample thread engagement while keeping the overall profile compact, making it ideal for confined spaces. The design eliminates the need for special installation tools; a standard drill, tap, and a screwdriver or the dedicated E‑Z LOK drive tool are sufficient to achieve a secure fit. The inserts are sold in packs of five, offering a cost‑effective solution for batch repairs, new builds, or preventative maintenance in industrial and scientific environments.

Usage

These inserts excel in applications where traditional tapped holes are prone to wear or stripping, such as in aluminum chassis, cast‑iron housings, magnesium alloys, and other soft metals commonly found in aerospace, automotive, and equipment manufacturing. They are perfect for repairing damaged threads, reinforcing existing holes, or creating new threaded locations in prototype and production parts. Because the inserts are compatible with standard metric and imperial fasteners, they integrate seamlessly into existing assembly lines without requiring redesign of tooling or fixtures. The ability to install them with everyday hand tools also means field technicians can perform repairs on‑site, reducing downtime and eliminating the need for specialized training.

Why Choose Us

E‑Z LOK has a long history of delivering high‑quality fastening solutions, and this threaded insert is no exception. The carbon steel material is heat‑treated to achieve a balance of hardness and toughness, ensuring the insert resists deformation under load while maintaining a smooth internal surface for easy bolt rotation. The self‑locking geometry provides a secure grip that prevents loosening due to vibration, a critical factor in dynamic environments. Each insert undergoes rigorous quality inspection, including dimensional checks and thread verification, to guarantee consistent performance across every unit. Additionally, E‑Z LOK offers responsive technical support and a straightforward return policy, giving customers confidence that any installation question or concern will be addressed promptly.

FAQ

Can these inserts be used in hardened steel?

No. The inserts are optimized for soft metals such as aluminum, cast iron, magnesium, and similar alloys. Using them in hardened steel may result in poor thread engagement and reduced holding power.

Do I need a special tap to create the external thread?

The external thread is formed by the insert itself; you only need to tap the hole to the correct size (7/8‑9) using a standard tap set. No additional tooling is required.

What torque rating can these inserts handle?

When installed correctly, the inserts can sustain typical torque values for the corresponding bolt size, generally up to 30 Nm for M6‑M8 fasteners, depending on the substrate material.

Is the pack suitable for bulk manufacturing?

Yes. The pack of five inserts is designed for both small‑scale repairs and larger production runs. For high‑volume needs, bulk packaging options are available through the distributor.

How do I remove an installed insert if needed?

Removal can be done with a standard screw extractor or by gently tapping the insert out with a soft‑face hammer and a suitable removal tool. Care should be taken to avoid damaging the surrounding material.
