🔧 Perma-Coil 5/8-18 SAE Fine Thread Repair Kit: Restoring Threads with Precision Review

In the end it wasn't needed thank goodness. This was a just in case purchase for a project that will now be in my toolbox just in case. But it looks like it's working fine.

Had to repair the threads in the aluminum transfer case. No drill was included (must buy 41/64" separately) but other than that it was all I needed including a couple of extra thread inserts when I screwed in two. Adorable the third time! So far so good - no leaks or problems.

This worked very well for what I needed. My table saw had a hole for the guard support but was never threaded from the factory. Use a 41/64" drill bit to ensure the hole is correct, then use a tap to tap new threads. I found I needed and appreciated the installation tool as the insert wants to pop out and would be difficult to reach. Insertion started without tools, will definitely look at other sizes from this manufacturer in the future.

Used to repair a broken bell thread on my Mercruiser Alpha I Gen 2. The kit included everything needed for the job except a 41/64 drill bit. I easily saved the $500 to $700 it would cost to replace a house. I will definitely use this type of set again.
