Frequently Asked Questions

What is a HELI-COIL tangless helical insert used for?

A HELI-COIL tangless helical insert repairs or reinforces threaded holes in metal. The screw-locking design resists vibration loosening, and the tangless feature eliminates the need for a break-off tang, simplifying installation. It is ideal for aerospace, automotive, and industrial applications requiring strong, reliable threads.

What are the specifications of the HELI-COIL AT3585-02C086 insert?

This HELI-COIL insert has a #2-56 thread size, coarse thread, right-hand direction, and plain finish. It is made from 18-8 stainless steel with a tensile strength of 200,000 to 250,000 psi. The pack contains 100 pieces, and the STI tap size is #2-56. It is compatible with metal substrates.

How to install a tangless screw-locking helical insert?

To install a HELI-COIL tangless insert, drill the hole to the specified size, tap it using the correct STI tap (e.g., #2-56), then use a tangless installation tool to wind the insert into the tapped hole. The screw-locking feature holds the insert in place. No break-off tang removal is needed. Follow standard thread repair practices for best results.
