stripped screw hole

[bcraig]

Hi, I hate to admit it as i have been tinkering with guns for 35 years but i stripped a screw hole in the bottom of barrel on a Savage mark II f 22 rifle. this screw is at bottom of barrel and holds trigger group to barrel at the back and under bottom of barrel. I have only about a thread holding the screw to the barrel. I only paid $125 for the rifle including tax and I am not going to send back to factory or pay someone else to fix my stupid mistake . I am wondering if I could put oil or a release agent on the screw and then fill the hole with something like JB weld and put screw in hole and let it set up and if this would remedy my problem ? I have heard of things that will form threads and since there will be no back and forth pressure on this screw if it would work. I dont have any drill and taps and besides I want to use the same screw as It has a shank that also serves as a type of lug that sets into the stock at the rear. Thanks ,Craig

HI,


About the only thing that I could recommend is to helicoil the hole.  Not sure if there is a size available as gun screws can be really fine.

Here is a website for info.

The JB Weld would probably work as it isn't a heavy recoiling gun. Also might look at the DEVCON products such as steel putty. I have not used their products, but several on the NEF/Handi forum say DEVCON makes product/s that have greater tensile strength than JB. FWIW

I would use SuperWeld before any of the other epoxies, it's got some impressive strength when compared to JB and Devcon.

This is a gun and it deserves a proper fix, which is not glue, which has no place on a gun.  Find the next larger size which will clean up the hole, it may be metric, whatever it is, just get a tap and proper tap size drill and fix it right.  If you glue it you will never be able to trust it as long as you have it, and after you die and some one else gets it, they will curse the idiot that glued in a screw.  Larry

Keenserts are the answer.  Been using them for over 35 years on cars, guns and all other kinds of stuff.  You drill the hole out to a specified size, thread it and screw in the Keensert thread insert.
