How to fix Sling Stud that keeps unscrewing (not stripped) on a Synthetic Stock?

[Aim1]

So, I have 2 new guns, a Savage 220 Bolt Action Shotgun and a Thompson Center Encore Pro XT .50 Cal Muzzleloader that both have synthetic stocks. Whenever I am carrying them the sling studs rotate. They are not stripped out.

When I searched online for solutions it was for rifles that had stripped studs and almost all of the results were for wood stocked rifles.


How do I fix these sling studs that keep unscrewing (not stripped) on synthetic stocked rifles?

Blue loctite.

 

[sabbfan]

A little epoxy should do the trick

 

[bdickens]

Loctite

Or just a bit of J B Weld.

What rskent said ^^^

JB Weld two part epoxy will fix it. I had the same problem with a Choat stock years ago. I used JB Weld and the problem was solved.
BUT! You will not be able to easily remove the stud afterwards.

What's better, Blue Loctite or JB Weld?

 

[Neo-Luddite]

Before any/either you could wrap the threads with teflon tape also. That might do the trick. Epoxy (ie. JB Weld, etc.) would make a repair that might not be removable without damage. Locktite would be my second choice after taping the threads.

Blue loctite is removable with hand tools, red is not without the assistance of heat.

Not sure locktite would hold when sling twists???? JB will hold, but as stated, you might never get it out again. Teflon tape is slick; used to seal pipe joints and make it easier to break the joint at later date.

By synthetic I assume some sort of polymer, plastic or carbon?
If so , will Loctite be effective? I think of it as more of a metal bonding agent.

Epoxy with no reinforcement, such as glass fiber or carbon fiber, is fairly brittle. I would use a very small trace amount of a epoxy. You should be able to break that bond later if necessary.

 

[dagger dog]

Super glue gel, put it on the screws and run them in.

I have never tried Loctite on plastic. I am guessing it will not work well. If you try it and it doesn’t you should be able to clean up the hole with alcohol then try tape then try JB Weld. Me? I would go straight to JB Weld unless you think that someday you’ll want to remove that sling stud.

My 2 cents

 

[Insignificant bill]

I vote Teflon tape

 

[22250Rem]

I was going to vote blue loctite until I got to the teflon tape suggestion. Never thought of that and I bet it might even be better than blue loctite.

 

[ancientnoob]

Teflon tape you don’t need anything else unless it is stripped out.

 

[stillquietvoice]

Uncle Mike's makes a push button stud with insert that you could epoxy in.

Same teflon tape as used in plumbing?

Same teflon tape as used in plumbing?

Yes. You could also try a couple layers of plastic grocery bag, if you have some laying around and want to try something right away.

 

[bdickens]

I have to correct myself. Loctite thread locker causes plastics to deteriorate and could possibly destroy your stock.

The Loctite company does make stuff for bonding plastics.

I might look into installing a threaded metal bushing into the stock & loctiting the sling swivel stud into that.

 

[MI2600]

I would vote for the tape as an easy fix. Then, go to others.
One question: Are the threads in the stock plastic?

I am also trying to picture in my mind how the swivel turns enough to become loose.

 

[FROGO207]

Before we all go a bit off, a question. When it unscrews all the way out do you see a metal or brass bushing with threads in the hole or do the threads look like a wood screw so that they grip on the plastic. That will guide an answer that will surely work. You could use threadlocker or similar if it threads into a bushing. Otherwise gluing to a plastic part might take some research to find what glues (and stays bonded) to stock plastic.

Teflon tape you don’t need anything else unless it is stripped out.

Over & over for the win IMHO.

Was the answer b4 loctite. Yes I M that old hehe
If it still wants to work out loose, take the thin portion of a flat toothpick, put it in the stud hole 1st, then put the stud back in. A round toothpick will most likely be too thick, as would the large end of a flat toothpick

Let us know how/what you did to fix, good luck!

 

[Steve S.]

Like others, I am trying to picture what use motion is turning the stud; unscrewing requires mechanical action. What action or use pattern takes place on a stock stud that causes it to back out?

 

[hps1]

I'm assuming threads in plastic stock have worn (if stud screws directly into the stock...no bushing) and teflon is being suggested to fill the gap between stud and female threads. If so, teflon will do that job, but teflon tape was originally used as a sealer and lubricant for threaded pipe joints and used for quality of preventing seizure of said joint in event it must be broken at a later date. Since pipe threads are tapered, teflon perfect for that application.

I would think for this application, the plastic grocery bag would be superior to actual teflon tape as that plastic would not have the lubrication qualities of teflon. The toothpick works great in wood, so would probably be good in plastic if depth of threads in the plastic stock is sufficient. Another easy "wedge" type solution would be to wrap the stud threads with sewing thread which would also tighten the joint, not be slick, and if it did not produce desired results would not leave a residue which would interfere with the various epoxy solutions.

Lots of good ideas have been suggested, let us know what works for you.
