A Closer Look at Coil Inserts
A helical coil insert is an ideal solution for repairing or reinforcing tapped holes in metal. But you need to know how to install a coil insert properly to get maximum performance. To get the best possible use out of a coil insert, you need to properly drill and tap the hole. Coil inserts compress during installation, and it’s that compression that secures the insert into place and keeps it from backing out. A properly drilled and tapped hole allows the insert to form properly, develop the desired thread tolerance, and provide optimum performance.
1. How do metal threaded inserts work?
Prior to installation, coil inserts are larger in diameter then the hole into which they will be installed. During installation, the coil insert compresses and is stretched out by the threads cut by the STI tap. After the insert is installed, the compressed insert pushes out against the wall of the hole. It is this outward pressure that keeps the coil insert in place.
2. What are the benefits of using helical coil inserts?
E-Z LOK's helical coil insert selection can help you quickly repair or reinforce tapped holes in soft metals. Other benefits include:
- Corrosion resistance
- Ability to withstand temperatures of up to 800°F.
- Protection from stripping and wearing.
