• All components come packed in a portable moulded box with an easy-to-follow instruction manual for user convenience.

Frequently Asked Questions:

Q. What is the function of an installation tool?

A. Helicoil 4937-150 kit includes an installation tool used to engage the tang of the insert to drive it into the material.

Q. What is a tap?

A. A high-speed steel tap creates internal threads in a hole or a pre-drilled bore. It features a tapered end with a series of cutting edges (or flutes) to cut and shape the threads.

Q. What is a tang?

A. A tang is a small piece of metal that protrudes from the end of the insert. The tang installs the insert into the threaded hole but once the insert is secured in place, the tang is no longer needed and must be removed. A tang-break-off tool grips the tang and snaps it off clearly and easily without damaging the threads or the insert itself.
