Helicoil Inserts

Precision-Engineered Helicoil Inserts for Strong, Lasting Threads

Helicoil inserts are crafted from high-precision, diamond-shaped wire, delivering an ultra-smooth mirror-like surface finish of 8–16 micro inches. Once formed into a spiral coil, they are installed into specially tapped holes to create permanent, high-strength 60° internal screw threads.

This advanced design ensures exceptional thread durability, even in high-stress environments — making them ideal for applications in aerospace, automotive, defence, and precision manufacturing.
