You can replace the lug screw and the nut with a standard threaded swivel stud. I think it's a 10-32 thread. I had to trim the 1/2" long stud to match the grip screw length. I believe the Hogue grip screw is a 10-24. I used a standard hex nut and filed the 2 sides to the same width as the factory nut inside the grip bracket.
