Work great!
Tried to put new grips on a pistol and couldn't get the existing socket screw to catch. Worked on it for about an hour with no results. Bought these and it was on in about 2 minutes. Great product!!!

Does not fit the Taurus Judge 4510
Does not fit the Taurus Judge 4510. Screw seemed to be a good quality just did not fit.

Needed to attach grip
We ordered these for changing out the grip on our Taurus Judge revolvers for the extended grip. Two of our three revolvers required this longer fastener to attach the extended grip. Only one used the same fastener that attached the shorter grip.
