So it's okay to use a turnscrew on a pin, in steel, and it's also okay to use it on a screw, in wood?

I wouldn't want to misuse the new turn screws, don't you know. As I understand it they are to be ground to fit the screws, and pins, on a particular gun. And, unless the slots are the same on another, should not be swapped around.?


May God bless America and those who defend her.
