Many thanks Dfarisheel.
I'd always wondered about the softness of brass for this purpose. Will avoid brass and go with some of the quality sets mentioned here.
One more question while we're on the screw topic or at least nearby--any gun blue-friendly breakaway products been good for anyone? We've always used PB (parts breaker) in the squirt or aerosol can but not for guns. Has anyone had good luck with other products for firearms application? I'd like to know before I need it!
