E-Z Lok Inserts for Metal

E-Z LOK external threads are standard size and pitch to permit use of standard drills and taps.

E-Z LOK inserts will not back out or vibrate loose. Immediately upon installation, microencapsulated adhesive begins to set and the newly installed insert can be fastened

to within minutes. In addition, the adhesive seals against liquids and gases to pressures

Easy removal Use a standard screw and bolt extractor to back out a damaged insert and then replace it with a new insert. Removal is simply a matter of overcoming the resistance to torque-out which has been produced by the thread locking material.

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

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.

To install a coil insert, you 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 probably already in your toolbox. For example, to install an E-Z LOK #EZ51618 (which has a 1/2-13 external thread), you would simply drill the hole with a standard 27/64 drill and then tap 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.
