Q: What’s the difference between E-Z LOK and coil threaded inserts?

A: There are two primary differences: design and installation.

Design
As the name implies, coil inserts are steel wire coiled in a spring-like design. E-Z LOK threaded inserts are screw machined out of solid steel.

Installation
To install a coil insert, the user must have a special drill, special tap, and special installation tool. If a tap breaks or the installation tool is misplaced, the coil inserts can’t be installed until a new tap or installation tool is purchased. E-Z LOK threaded inserts have standard size/pitch threads so they can be installed using standard tools you probably already have in your toolbox. For example, if an E-Z LOK with a 1/2-13 external thread is being installed, the user simply drills the hole with a standard 27/64 drill and then taps the hole with a standard 1/2-13 tap. Once that’s done, the insert is threaded into the hole like an ordinary fastener using a screwdriver, bolt and jam nut, or an E-Z LOK drive tool.
