Instructions

A resistant thread in 4 steps:

Step 1:

Drill a core hole or drill out the damaged thread

Step 2:

Create a receiving thread

By cutting using screw tap

Without cutting using thread moulding for an even more resilient receiving thread

Step 3:

Set the thread insert

The helical insert can be mounted both mechanically and also by hand using the corresponding screw-in tool.

Step 4:

Break the pin

Separate the follower pin by tapping gently on the predetermined break point with a pin breaker, and then remove. Automatic pin breakers are also available for series production.
