Striped threads

Post by Rack shack » Tue Nov 01, 2016 7:22 pm

My model 8 has some striped threads on the barrel nut part that is attached to the barrel witches is used to screw the take down swivel into. So with the forarm on the screw will not tighten down to hold it on. And ideas on repairs. The take down swivel threads are good. Not sure what the thread size this is to see if theirs a insert for it pretty small.

I'd imagine a good machinist could line you out on this. Any other thoughts y'all?

Well everybody would love to have a good machinist on hand.If not an alternative might be a strip of thin soft metal inserted to give the screw something to grab. If that doesn`t work you might try my go to fix it "JB Weld". Probably have to drill out the stripped threads some to give enough room. JB in the hole being sure to degrease well. Then with release agent (light oil on the threads) push screw into the hole and allow the JB to cure. Be sure to support the screw keeping it straight during the cure. Next day or the next gently back the screw out from the newly formed threads. Have made some repairs with it and really been surprised with how well it holds up.

A. Try your local tech school machine shop. B sure to take only the parts to the building. Nothing assembled.
B. Try threaded inserts:

C. worst case the hole could be MIG welded, then drilled & retapped.

Notice this is a riveted part; Remington loved to do this on select pieces to make things difficult. Good luck with the repair, it could cost more than a replacement.

Thanks for the replys. I'm hoping I can find a insert. What I'm thinking of maybe trying. It's only the first couple of threads that are striped. With the forarm on and the take down swivel in it only uses those first few threads. If I can extend the length of the take down screw to thread it down deeper I should be ok. Not sure if the would be a good idea or not hate to cut it if it don't hold
