Thread size of Rem 783 guard Screws??

[hoz53]

Does anyone know the thread size of Rem 783 guard screws? The one I checked looked to be 32tpi and .241 Dia. I'm betting metric. Thanks

I just woke up , but I have it somewhere. I don't remember it being metric . I think it's 1/4 x32 as that's the die I bought and it's still sitting next to me ! Wow that was easy , now for my coffee .
I first tried some winchester screws and Springfield screws .
The receiver and bolt , trigger are the same as the Marlin xl-Xb-7

Manufacturers can use any screw size they want . It was common in early 1900 s to use whit worth , a British std of the last century , like our SAE .
Winchester use the 1/4 x32 , some have used 1/4 x 27 but I can't remember which one . The book of bolt rifles by DeHass has the receiver screw specs . Still enjoying coffee .

Ok found the book . Here are just a few 1/4x 22,26,27,28,25,30,
Then you have a few 15/64 x26,34,28
And I was WRONG on the 1903 Springfield , that is1/4 x25

It's no use trying to understand why Remington would not standardize their screws but it is entirely in keeping with their spastic mentality when it comes to products.

Yeah that's what I thought. Hopefully remington doesn't get as bad as savage in this regard.

Thanks Ggmac-- I will figure out if these are 1/4-32-- I'm adapting a 783 to a savage stock so I need some stock makers type screws. I think I will see if I can make some on the lathe just to see if I can do it.

Get that thread pitch gage out.

I use 3/8x4" std bolts , turn or cut the hex off turn threaded section , usually just an 1 1/2 " down to .250 , now flip the piece around so the 3/8" solid shaftis in the lathe and start cutting . The 3/8" shank gives a larger area for insetting pillars and is less liable to flex if it's out of the head a bit .

Yeah it's right up there with the chuck key. Used it to check the guard screw to start with. After looking it seems 1/4-32 taps and dies are easy to find - not so with nuts and bolts.

That's a good idea thanks

Probably because 1/4-32 is classified as NFS (National Fine Special). If we're gonna' work on firearms, the hardware/industrial supply isn't the place to be looking for bolts/screws.

Ok thanks I'll look in Brownells.
