3 Reasons to Use E-Z LOK Solid Wall Threaded Inserts

This quick video shows you why E-Z LOK threaded inserts for metal are the best option for your next job.

Solid Wall & Coil Thread Inserts: What’s the Difference?

When dealing with thread repair or reinforcement in metal, it's crucial to choose the right kind of threaded insert for your specific needs. E-Z LOK offers two primary types of threaded inserts for metal—Solid Wall and Coil (helical). But what distinguishes them from one another?

Solid Wall inserts are machined out of solid steel (carbon or stainless) and feature standard internal and external threads. This allows Solid Wall inserts to be installed using a standard drill, tap, and a flat blade screwdriver or bolt and jam nut. Optional drive tools are available. Coil inserts are made from wound stainless steel wire that, once installed, create a strong replacement thread. Coil insert installation requires the use of a special tap and install tool.

How Do Metal Threaded Inserts Work?

Threaded inserts for metal offer a long-lasting method for strengthening threaded holes in metal. By providing a stronger, more durable thread, inserts allow a threaded fastener to be installed and removed multiple times without damaging the tapped hole. This makes threaded inserts an ideal solution for repairing or reinforcing threaded holes that are susceptible to stripping.

How Do You Install Threaded Inserts for Metal?

Installation is as easy as drilling, tapping, and installing the insert. Solid wall inserts for metal have standard OD threads, so standard size drills and taps are used to prepare the hole for installation. Solid wall inserts can be installed with a flat blade screwdriver, bolt and jam nut, or optional drive tool. Coil inserts require the use of a special, STI tap that cuts a thread designed to form the coil insert into the desired thread. Once the hole is properly drilled and tapped, a coil insert installation tool is used to thread the insert into place.

Which One Is Right for You?

Choosing between solid wall and coil thread inserts for metal depends on your application. Solid wall inserts offer a strong, solid steel design with standard threads, but require a larger hole than coil inserts. If hole size is an issue, or if temperatures will exceed 300 degrees F, coil inserts are the solution.
