E-Z Lok Externally Threaded Insert, C12L14 Carbon Steel, Meets AISI 12L14, 5/16″-18 Internal Threads, 1/2″-13 External Threads, 1.000″ Length, Made in US (Pack of 5)

Description

Product Overview

The E‑Z LOK externally threaded insert is engineered from high‑grade 12L14 carbon steel, a material that meets AISI 12L14 specifications for strength and corrosion resistance. Each insert measures 1.000 inches in length and features a dual‑thread design: a 5/16‑18 internal thread paired with a 1/2‑13 external thread, allowing it to lock securely into a wide range of soft‑metal substrates.

Designed for ease of use, the insert can be installed with standard hand tools—no special taps or proprietary drivers are required. The self‑locking geometry ensures that once the insert is turned into a pre‑drilled hole, it grips firmly, providing a reliable threaded anchor that resists loosening under vibration or repeated assembly cycles.

With a compact footprint of 3.75 x 3.15 x 0.65 inches and a lightweight of just 0.48 ounces per unit, the inserts are convenient to handle and store. The pack of five offers a cost‑effective solution for batch repairs, prototype builds, or small‑scale production runs, delivering consistent performance across multiple applications.

Manufactured in the United States, these inserts benefit from strict quality control processes that verify dimensional accuracy and thread integrity. The product has earned a high customer rating of 4.9 out of 5 stars, reflecting its reputation for reliability and ease of installation among engineers and hobbyists alike.

Whether you are reinforcing a damaged hole, creating a new threaded feature in a soft metal, or need a durable fastener for an assembly that will be disassembled frequently, this E‑Z LOK insert provides the strength and repeatability required for demanding industrial and scientific projects.

Usage

These inserts excel in environments where soft metals such as aluminum, cast iron, magnesium, and certain alloys are used. Typical applications include aerospace component repair, automotive engine brackets, marine hardware, and electronic enclosures where weight savings and corrosion resistance are critical.

Installation is straightforward: drill a hole to the recommended diameter, tap the hole with a standard tap matching the external thread size, and then turn the insert into place using a screwdriver, bolt, or the dedicated E‑Z LOK drive tool. The self‑locking action eliminates the need for adhesives or additional locking mechanisms.

Because the insert provides a hardened internal thread, it can accommodate frequent assembly and disassembly without stripping, making it ideal for maintenance‑intensive equipment and modular designs that require reliable re‑torquing.

In addition to repair work, the inserts are useful for creating new threaded connections in prototype parts, allowing designers to quickly iterate on mechanical designs without committing to costly machining operations.

FAQ

What types of metal can I use these inserts with?

The inserts are designed for soft metals such as aluminum, cast iron, magnesium, and similar alloys. They work well in applications where the base material is relatively easy to tap and where a strong, reusable thread is needed.

Do I need a special tool to install the insert?

No special tools are required. You can install the insert using a standard screwdriver, bolt, jam nut, or the optional E‑Z LOK drive tool. The design is optimized for use with common hand tools found in most workshops.

How many times can I reuse the same insert?

Because the internal thread is hardened steel, the insert can be assembled and disassembled many times without stripping. It is suitable for applications that require frequent maintenance or part replacement.

Is the pack of five sufficient for larger projects?

The five‑piece pack is ideal for small‑scale repairs, prototypes, and limited‑run production. For larger projects, bulk quantities are available through our wholesale channel to ensure you have the inventory needed for high‑volume assembly.

What warranty or support do you provide?

We offer a satisfaction guarantee and a responsive technical support team. If you encounter any issues with installation or performance, our engineers will work with you to resolve the problem or provide a replacement as needed.
