Threaded Insert E-Z LOK 12L14 Carbon Steel 0.687″ Length Pack of 5

Description

Product Overview

The E-Z LOK 12L14 threaded insert is engineered from high‑grade carbon steel to provide a robust, self‑locking thread solution for a wide range of soft metal substrates. Measuring 0.687 inches in length, each insert features a 5/8‑11 internal thread and a 7/8‑9 external thread, delivering a secure fit that resists loosening under vibration and torque. The design incorporates a tapered shank that expands slightly when driven, creating a tight interference fit that maximizes holding power without the need for additional locking compounds. These inserts are supplied in a convenient pack of five, allowing users to stock essential fasteners for repetitive maintenance, repair, or new assembly projects.

Usage

Designed for use in soft metals such as aluminum, cast iron, magnesium, and similar alloys, the E-Z LOK threaded insert excels in applications where traditional tapped holes may strip or wear out quickly. Typical environments include automotive repair shops, aerospace component maintenance, marine equipment refurbishment, and hobbyist fabrication workshops. The inserts are ideal for reinforcing existing tapped holes, repairing stripped threads, or creating new threaded connections in sheet metal brackets, engine housings, and custom‑fabricated frames. Installation requires only a standard drill to create the pilot hole, a conventional tap to cut the internal thread, and a screwdriver or a simple drive tool to seat the insert, making the process fast and accessible to technicians of all skill levels.

FAQ

What size pilot hole is required for installation?

The recommended pilot hole diameter is 0.31 inches (7.9 mm). Drilling to this size ensures the insert seats properly while allowing the tapered shank to expand for a tight fit.

Can these inserts be used in hardened steel?

While the insert is optimized for soft metals, it can be used in mildly hardened steel if a pre‑drilled pilot hole is provided and the installation torque is carefully controlled to avoid damaging the threads.

Do I need a special tool to drive the insert?

No special tool is required. A standard flat‑head screwdriver, a bolt, or the optional E‑Z LOK drive tool can be used to turn the insert into the tapped hole.

How many inserts are included in each pack?

Each package contains five threaded inserts, each measuring 0.687 inches in length, providing a cost‑effective solution for multiple repair or assembly tasks.

Are these inserts compatible with standard metric bolts?

The inserts feature imperial thread sizes (5/8‑11 internal and 7/8‑9 external). For metric applications, a compatible conversion kit or metric‑threaded insert should be selected.
