Method and principle

Thread repair with HELICOIL®

Excessive bolting torque, corrosion and even wear – these are just some of the reasons for thread damage.
HELICOIL® Plus thread inserts come in a variety of designs for quick thread repair. Using non-wearing HELICOIL® Plus thread inserts not only repairs threads but also increases the load capacity of the thread.

The process is very simple:

Simply drill out the defective thread and use the combined HELICOIL® Plus drilling and tapping tool to cut a new holding thread. You can then install the HELICOIL® Plus using the installation mandrel provided for this purpose. Now all you need to do is break off the tang using the tang break-off mandrel and the new thread with the HELICOIL® Plus thread insert is ready for use.
