Glock front sight tool

Well, I just got my new Warrent tactical sights (plain rear night sight front) yesterday. Went digging for an old Aerotek front sight tool that I had from years ago…well, I lost it I guess and can’t find it anywhere. I think I’ve got a really small socket head that will fit the tiny little screw/bolt, but the socket flares too much to get in good. Anyone know if I can get a hand held nut driver at someplace like home depot (that will fit inside the slide OK)?

thanks for any help.

3/16 hex. You need to find or trim down the outside diameter to fit through the opening in the slide. Use the red loctite. You will still be able to remove the nut if you have to and it holds a bit better than the blue.
