I know a lot of you collect more than just Smith & Wessons so I thought I’d ask here if anyone has a Stevens Pocket Rifle with its stock. This one belongs to a friend who lost the stock thumb screw in a move and left it with me to see if I could find a replacement screw that would work. The chances of finding an original are remote but I had hoped it would be a standard size thread or, failing that, figure out the size and pitch and get a screw made. It seems to be a Number 10 screw but it is not a 10-32 or 10-24 TPI.

BTW, this Stevens has an 18 inch barrel and is .32 centerfire.

Did you try counting the threads? Use a dental pic, count the threads measure the amount you moved then multiply to get to an even inch. At least you’ll know what you are looking for. Good luck.


There are 10-16 screws around.

There are lot of screw pitch gauges on Ebay for around $12. They are handy for lots of stuff. Get one.That and a caliper will tell you what you need to know

I usually use a magnifying glass and a pair of calipers... set the calipers to an even number of threads and do the math. Usually get pretty close.

Back when I was working we had black plastic round heads that would fit over a socket head cap screw so it could be like the lost thumbscrew they were tight and had to be pressed on to the shcs, you may have to re-tap to a coarse 10-24. This will work if your friend wanted to try it. Jeff

At some hardware stores they have indexes of "Gun Screws" and oddball screws. Get a screw that fits the gun! not fit the gun to the screw! That destroys value at any condition level!

Check Gun Parts Corp of America for the exploded view drawing, and maybe even a part or two!

It might be 3/16"-36
That's about a #10 machine screw size and one that some of the older guns used on sights and accessorys.

If you have an older Winchester lever action rifle (1892, '94, '73,,) that is drilled and tapped on the upper tang for a tang sight and has plug screw(s) in the factory holes,,or perhaps a tang sight on it and orig spec forward position tapped hole w/ screw...
Those are 3/16-36 thread hole, plug screw and/or sight base screw.

If you have one handy you can try it in the Stevens to see if it fits.

Beautiful condition Stevens, looks like a New-Model Pocket Medium Frame 2nd.

I'd do everything possible to find an orig or make a repro and finish it to match.

Apparently Stevens had oddball threads. A friend brought me an old Stevens .22 that needed some parts, including a screw. My micrometer told me no modern screw was the same diameter so I turned a soft wood dowel to fit, screwed it in & when removed it was a thread count I'd never heard of. I had to turn a steel rod to diameter & thread it. I must have spent the better part of an hour making 1 screw... the rest of the parts were "fun" challenges too.

Do you have a thread gauge?

9mm Mac-10 Machinegun silencer threads are 5/8-11 1/2ish threads probably a Walther standard thread since a lot of accessories interchange. 45ACP and 380 versions are some other threads.

Neat gun. Somebody should make a remake in .22 Magnum!

I've checked it as closely as I can with my thread pitch gauge and it seems to be 28 TPI. (It's NOT 1/4x28 - that's too big). As pointed out by others, unusual screw diameters and pitches are often found in firearms - especially old ones.

From Flayderman's book I've identified the rifle as a Stevens Hunter's Pet No. 34 Pocket Rifle. It does have the 1-1/4" frame. It seems that Stevens made a bunch of variations of the "Pocket Rifle".

It's possible to drill and tap it with a larger fastener buy I would only do that as a last resort. I'm sure the owner would like to keep it as original as possible and not "monkeyed with" except for making a new screw.

Thanks everyone for your insights.

There are 10 28 screws available. I’ll check tomorrow to see if I have a die.

I just got home from work and checked my box. Sorry no die.

We have a winner! The photo you attached mentioned "brass bibb screw". I had a jar of valve stem repair parts, washers and screws that a plumber had given me that I had thrown in with some brass machine screws. One fits!

Problem solved.

Thanks to all for your suggestions.

I love a happy ending!
