Frequently Asked Questions

What is a HELI-COIL helical insert used for?

A HELI-COIL helical insert repairs or reinforces threads in metal. It creates a strong, wear-resistant M4-0.70 thread in softer materials like aluminum or cast iron. This free-running tanged style is ideal for applications requiring repeated assembly and disassembly, common in automotive, aerospace, and industrial maintenance.

What are the specifications of the HELI-COIL M4-0.70 insert?

This HELI-COIL insert has M4-0.70 metric coarse threads, right-hand orientation, and a 4.2mm drill size. It is made of Nitronic 60 metal with a tensile strength of 200,000 psi. The plain finish, tanged tang style comes in a 100-piece pack (MPN A1084-4EN080).

How to install a HELI-COIL tanged helical insert?

Drill a 4.2mm hole, tap it to the specified thread depth, then use a HELI-COIL installation tool to wind the insert into the tapped hole. After installation, break off the tang with a punch. Ensure the insert sits slightly below the surface for proper thread engagement. Follow standard thread repair practices.
