Heli coils VS EZ-LOK

[mocharand5@aol.com]

I have both. I find the EZ-LOK type much better and requires no kit to buy. 
You basically drill and tap the hole out to the next size, 3/8-16. Screw in 
the steel or stainless insert, whatever you prefer, and your back to your 
5/16 threaded hole.
The insert is 3/8 threaded OD and 5/16 threaded ID.
These are used heavily in the manufacturing industry. They come in all sizes.
