Need help finding screws

[Regular Joe]

I have a GM drop in barrel for a T/C that I need to shim to get it to fit in my stock. The screws that hold the lug on the barrel are too short after the shims. They only have maybe two threads holding the lug on. Does anyone know where I can find some screws? I don't know the tread pitch. I need them about 3/8 in long. The hole is tapped far enough in. Thanks! Joe

I don't know what thread they are either, but everything on a TC should be standard thread. They are probably #8 screws. Any hardware store will have them.

This is a Green Mountain barrel, it's not a TC part or a standard screw. But, I'll check the specialty drawer at Lowes.

I would really be surprised if Green Mountain used metric screws. I'm sure most are aware, but the quick and easy test is to find the nut drawer and find the size that way. I assume this a counter sunk screw, either flat or allen head. I've never been to lowes, but they should have it if they are worth anything.

You may have to go to a real old school hardware store.

If you can't take the barrel, take a screw, test it on a known size nut to be sure the thread pattern is right.

I've done that and sometimes had to get a longer screw that could be filed down--carefully.

If you have a Cardinal True Value store, they may have them. The local one carries an assortment of gun screws.

Numrich! Should have known. Fillister Head Screw, New (6-48 x 3/8") $2.75 each. Price plus shipping will hurt, but I need them.

I found some on flea bay for less. Thanks for the info, I have the same problem.

All screws are not created equal. There are a lot of inexpensive screws and bolts for sale at places like Home Depot, but in my experience they are mostly made of poor quality steel and their tolerances are not that tight. Maybe get one to find the right size, cannot believe it’s not US standard. After find a place that sells good quality. Agricultural supply stores usually have good quality. They might even let you bring the gun it to find the right one.
