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).

Helicoil 5521-4 0.25-20 Inch Coarse Thread Repair Kit Review

No instructions, so I would suggest finding a friend or relative with a vice and ordering the required drill bit to open up the hole first- took just a few minutes start-to-finish and saved me a $165 minimum charge to have this done at a camera repair facility!
