Factory screw stuck

[Flash]

ATRS rings and rail arrived yesterday.

Rem 700 drilled and tapped for scope mount. Three of the tiny little slotted screws came out easily. Front one refuses to budge.

It’s as if that screw was installed by an anti-gunner mole in the factory, using epoxy and an air gun.

Or maybe it's not a screw at all; only an etching where the hole's supposed to be.

Tried the rubber band and cardboard techniques. Let it sit with Release-all overnight. Still won’t budge.

Got any ideas?
Thanx

heat it a little then try it

Stick the correct size hollow ground bit/screwdriver into the screw...heat the bit/screwdriver with a torch (not the screw). Apply just a small amount of pressure and continue to heat the bit until the screw begins to move. Do not over heat...

Impact driver.

If gentle heat doesn't work you could drill a smaller hole in the screw and use an easy out.

At the same time you are applying torque to the screw driver tap downwards on the end of the screwdriver with a small hammer ... sometimes that tapping pressure will loosen a tight thread.

Tried the tapping method a few times to no avail.

Not sure easy outs that small even exist.

I understand heating when unsticking a jar lid. But that will expand the screw, which if it expands will be more difficult to extract, no?

Guess I'll try it with a soldering iron.

I'll try it with a soldering iron.

Soldering iron didn't work.
