HelicoilEinsätze

Helicoil Einsätze, often referred to as Helicoil inserts or thread inserts, are precision-engineered coil springs made from high-tensile stainless steel or bronze wire. They are primarily used to repair damaged threads in a variety of materials, most commonly in metal. When a screw or bolt is stripped or the original thread is damaged, a Helicoil insert can be installed to create a new, stronger thread.

The installation process typically involves drilling out the damaged thread, tapping new threads for the Helicoil, and then screwing in the Helicoil insert using a special tool. Once installed, the Helicoil becomes a permanent part of the threaded hole. The unique design of the Helicoil insert allows it to distribute stress more evenly than a standard tapped thread, often resulting in a thread that is stronger than the original. They are widely used in automotive, aerospace, and general engineering applications where thread integrity is critical. They can also be used to upgrade existing threads to a stronger or different size.
