Frequently Asked Questions

What is a HELI-COIL helical insert used for?

A HELI-COIL helical insert repairs or reinforces threads in metal substrates. The screw-locking tanged style, like the #4-40 coarse thread insert, provides vibration resistance and distributes load evenly, extending fastener life in industrial assemblies.

What are the specifications of the HELI-COIL A3585-04CNW224 insert?

This HELI-COIL insert has a #4-40 coarse thread, 18-8 stainless steel construction, tensile strength of 200,000 to 250,000 psi, and a Dry Film Lubricant finish. It requires an STI tap size of #4-40, is right-hand threaded, and comes in a 100-pack for inch-system applications.

How to install a HELI-COIL tanged insert?

To install a HELI-COIL tanged insert, drill the hole to the specified size, tap it with the correct STI tap (here #4-40), then use a tang break-off tool to insert the coil. After installation, break off the tang for a secure, screw-locking thread in metal substrates.
