Jewell trigger screws

[redbullitt]

Have a rem700 here with a jewell trigger installed.

Appears to be missing the screw on the pull weight adjustment! Bad luck since I guess jewell is dead now?

Does anyone know what size/threading it is? Hope to get a replacement in there so I can shoot it or at least not lose the little spring lol...

I’m going to segway off this, I sold the rifle to him and when it shipped the trigger worked. Guess it got jostled out in shipping or at the ffl, idk.
I’m swapping out triggers with him so I’ve inherited this issue jewell now.

It’s screw 3 here, pull weight adjustment, that’s missing.

Would anyone out there be able to pull theirs and tell me what thread pitch it is? The hole is too small for my thread pitch gauges to fit inside of like I had hoped.
If I know the pitch I can buy and fashion a replacement, if not make it outright on my lathe. Never done something that small but sounds fun.
Sucks jewell itself isn’t around any longer.

Is screw number 1 the same size? If so you could pull it out to get a measurement.

I actually don’t have an Allen small enough here at the house, it’s smaller than 1/16” or 1.5mm, I think it’s a 1mm
I’ll have to see at the ranch shop this weekend and hope I got it there

It is the same threads between the two screws
the screw is 48 tpi
the overall length is .188
the major pitch diameter is .110

The head uses a .05” allen


Note the key way for loctite I guess, some goop is in it.

Way too small for me to cut myself. Anyone have any guesses on what spec this might be?

The lengthwise cut usually has a nylon strip to make it self locking.

I’m glad yall were coming up with 4-48 too, I was looking at the mcmaster carstainless ones

Hmmm, I guess that’s gone or just all chewed up. I’m not going to fret it too much as they come in 25 packs, I’m going to be trying to lose them now lol
