E-Z LOK Threaded Insert 12L14 Steel 3/8-16 & 9/16-12 Pack5

Description

Product Overview

The E-Z LOK externally threaded insert is engineered from high‑grade 12L14 carbon steel, a material that meets the stringent AISI 12L14 specification for strength, durability, and corrosion resistance. Each insert measures 1.000 inch in length and features a dual‑thread configuration: a 3/8‑16 internal thread that mates with standard machine screws and a 9/16‑12 external thread that engages securely with pre‑tapped holes in a variety of soft metal substrates. The design incorporates a self‑locking mechanism that eliminates the need for additional locking compounds, providing a reliable, vibration‑resistant connection even in demanding industrial environments. With a compact footprint of 3.3 x 3.35 x 0.65 inches and a lightweight of just 0.48 ounces per unit, the inserts are easy to handle and store, making them an ideal solution for both on‑site repairs and in‑shop inventory.

Usage

These inserts are specifically designed for use in soft metals such as aluminum, cast iron, magnesium, and their alloys, where traditional fasteners may strip or fail. They excel in applications ranging from aerospace component maintenance, automotive repair, marine equipment refurbishment, to hobbyist projects involving CNC‑machined parts. The installation process is straightforward: drill a hole to the recommended diameter, tap the hole using a standard 9/16‑12 tap, and then turn the insert into place with a screwdriver, bolt, jam nut, or the optional E‑Z LOK drive tool. Because the inserts are compatible with standard tools, technicians can perform repairs quickly without the need for specialized equipment, reducing downtime and labor costs. Their robust construction also makes them suitable for high‑vibration environments, such as machinery housings, pump casings, and gearboxes, where a secure threaded connection is critical for safety and performance.

FAQ

What metal types are compatible with these inserts?

The inserts are optimized for soft metals such as aluminum, cast iron, magnesium, and their alloys. They can also be used in certain low‑carbon steels where the material is not overly hard.

Do I need a special tool to install the insert?

No special tools are required. A standard drill, a 9/16‑12 tap, and a screwdriver or bolt are sufficient for installation. An optional E‑Z LOK drive tool can speed up the process but is not mandatory.

How many inserts are included in the package?

Each package contains five individually packaged inserts, providing enough quantity for multiple repairs or bulk inventory needs.

Can these inserts be used in high‑vibration environments?

Yes. The self‑locking design and robust steel construction make the inserts resistant to loosening under vibration, making them suitable for machinery, automotive, and aerospace applications.
