Thanks for the replies, the responses given make sense. Better to replace a basically sacrificial parts than the entire cast part.
As part of my main hobby I do foundry work in aluminum, bronze and small grey iron castings; for me if a part goes south I can make a new one. I would not want to recast some of my more complex parts in case something went wrong with a threaded section so I can see the utility of a helical thread insert. Jerry http://tanks.linite.com |

I did a Google search on the part number I used, and it came back as being 10/32.
The number is 3591 3CN380 Search on that and you should find what you need. I got mine on eBay, genuine Stanley.

They do make locking heli-coils. They are red. Probably the best bet to get, to keep the rods from working loose. I always try to get some whenever I purchase a kit.

Thanks that was the info I was looking for.
Any link? What about the tools to do it? I see some modify usual tools for removing the old coils. For the install, you only need a tap wrench, or something else?

Is there a standard length for 10-32 helicoils? Some seems shorters than others. I'd rather have the biggest one. More strenght. The kit on amazon provide an install tool, not a removal tool. I can't see if the coils in my cocking piece are tangless or with broken tangs. The removal tool is different regarding the coil: |

Heli-coil lengths are rated by diameters. 1.5 diameters is usually the standard. Example for a 1/4" bolt, the 1.5 diameter would equal the insert being 3/8" long., a 2 diameters, would be 1/2" long, etc.
