Trying to find 1/2-24 socket head screws for action and can't.

[rooneyrc]

I'm trying to replace Browning Abolt-2 slotted screws with a torn or hex head socket screw. Browning says the thread pitch is 1/2"-24. I can find screws with this dimension anywhere. Any help would be appreciated. I thought about seeing if a machine shop could make me some but assume that would cost more than it's worth. Thanks

That is your muzzle thread, bud. Look for your action screw thread.

Believe they're going to metric - M6 x .75? Definitely not 1/2" action screws.

Once you ID the proper size, check McMaster Carr.

I’ve also used mettec for titanium action screws.

Have an Ace hardware locally? They usually have all kinds of crazy bolts and screws.

1/2” action screws, fuck that’s beefy.

How does every guy not have several of these lying around?

Easy.
I have calipers, micrometers, and thread gauges.

I talked to another person at Browning and got this answer. 10-24 rear and for pre 1998 Abolts/Abolt-II's the front was 1/4" x 20 and for post 1998 Abolts/Abolt-II's was 1/4" x 28. However when I tried screws this size on a 2007 Abolt-2 the 10-24 didn't work. It was like talking to the DMV dealing with Browning.

Go to Fastenal. Bring your action with you, but leave it in your truck.

LEAVE THE ACTION IN YOUR TRUCK.

Go in the store, tell them you need to use the thread gauges on something big and it’s in your truck.

Go out to your truck, figure out the thread size, go back in store and buy your bolts.

I'm late to the party, but I just swapped mine out on my A-Bolt II. The front was 1/4-20 x 1.125 and the rear was not 10-24. Nothing at the hardware store fit it but the threads mate up to 1/4-28. The best I could tell that one was 10-28. Since those are basically non-existent, I just tapped the rear 10-24 and moved on with life. The rear was 0.750" long.

This is a horrible idea.

Why would you tap it to something different when doing so is going to compromise the integrity of what little thread you had?
