Perma-Coil 5-40 Thread Repair Kit Review

The Perma-Coil® kit number 1208-015 is 5-40 inch coarse thread and comes with the 5-40 insert tap (not a regular 5-40 tap. The required 5-40 insert tap is larger than a standard 5-40 tap and requires a 9/64" drill bit size hole.).

This kit comes with 12 stainless steel inserts, a 5-40 insert tap and an installation tool for the inserts.

Simply drill a hole using a 9/64" drill bit (not included), then tap the hole with the included tap, you next install the insert onto the insert tool and thread the insert into the hole just about 1/4 to 1/2 turn below the starting threads. Then screw the insert tool back out and if needed break the little tang off of the insert (instructions on back side of packaging).
