Derby cover screw

[1bdi]

I just replaced my compensator with the SE up grade.
Went smooth as cheese thanks to the tips and advice of this site!!!
Had to grind the inner primary case to get things out as was told I would.

My problem now is one of the derby screws won't let go.I've twisted a torx bit trying to get it out.
Any thoughts?

Drill the head off it should twist out with your fingers then

I replaced mine with allen screws and make sure that you put anti sieze on them when they go back on....

This should do it.:s

My suggestion would be to : With a impact driver or allen key in a socket, tap on ratchet extension to break free. Then try a tight fitting allen key to loosen.
Hope this helps.

Well...
I tried giving it a sharp tap with a small hammer....nuthin!
I put a little heat on it...nuthin!
So I drilled it out and the remaining bit twisted out with my fingers.
Go figure?
Like y2kflhr said, I'm going with allen screws!!

Thanks for the help

And antisieze:s

You only need to torque them to 80 in lbs. Spec is 86 to 108 in lbs., and that is way too tight.

And antisieze:s

Changing them to stainless allen screws is a very good idea, also using antiseize compound or sealer is a very good idea...two disimilar metals and moisture will induce corrosion in short order.:57:
