Hello, I am looking for a stainless strain screw for a model 64 square butt for a friend of mine. He is getting light strikes sometimes, and it looks like someone shorten the screw in the past. I have had no luck finding any on line, except 1 on Ebay for $9. I can find them for round butt, but not square. Does anyone know a source at a decent price? Thanks

Sure. Midway has them in stock, but hold on to your hat, they're expensive....... $1.99 (batteries not included)

EDIT: This is the ROUND BUTT screw, not the square butt screw the OP requested

an old trick if you needed extra length was to take a spent small
primer out of a shell case, remove the anvil and put it on the
strain screw.

Thanks, but it looks like that is for a round butt. I could be wrong, but I thought the screw for a square butt is a little longer?

Hey, now that may work. Worth a try if I can not find one, thanks.

I must be half asleep this morning. Sorry about the link to Midway.

I do have some extra ones in my parts bin.... I can send you one free of charge if you are unable to find one. Just PM me, or e-mail me an address. BTW, I checked at Numrich and they are out of stock.

No problem at all. I appreciate your help and your kind offer. Let me dig around a little more and see if I can find one. If not, I may take you up on your offer, thanks, again!

Should be able to get one from S&W directly.

I never thought of that, thanks!

You can make any length you want from a Grade 8, 8-32 Cap screw. I start with a 1/2" when setting up a K frame with a strutted mainspring for IDPA SSR

I am going to try tomorrow, just too busy at work today. I think I work the hours they do,lol. In the meantime, I tried the spent primer trick. It fit on the end of the strain screw nicely, I have a feeling it might just work. My friend said it may be Saturday before he can try it out though. Thanks everyone for your advice, it was a big help.

S&W does not have any, does not expect to ever have anymore. I completely understand, it is considered a obsolete part. My used primer may work, and I may order from ebay.

???? I don't understand "S&W doesn't have and and doesn't expect to ever have anymore". They are still currently manufacturing SS revolvers.

Both me, and my parts bin are now officially "Obsolete".......seems kind of sad. There are a lot of stainless square butt frames out there.

Strange.....I can't even give these things away!

I am not positive, but they may not make any square butt revolvers anymore. The screw for the round butt is different length. You can find plenty of that size.the
