View Full Version : Stripped sight screw head

March 5, 2012, 07:52 PM
How would y'all fix a stripped sight screw head? I tried to take my filler screws out the other day, and one was so stuck in that the head stripped.

I would try a left hand drill bit before anything else, if you can find one the right size. Alot of times it'll back 'em right out.

Problem is, I tried that, but it was too small it couldn't get a good grip. So I drilled it out. How do I rethread it to a little bigger size?

Since you already drilled the filler screw see if you can find a small easy out,I have a set of micro easy outs from sears.

He is past the easy out stage.

Yeah, I tried a small easy out, but the screw was so soft, it couldn't get a grip. Now I don't know what to do.

Did you drill it to the screw's minor diameter? or major diameter?

What do you mean?

If the thread was 6-48, you can get "oversized" 6-48 taps and screws from Brownells. No need to drill it to tap it larger.

If you drilled it out too large, you can convert to 8-40 by using a #28 drill and 8-40 plug and bottom taps.

(If a hole is shallow, I often cut one flute in a screw with a Moto-Tool cutting disk to act as a tap and get an extra turn or two.)
