Frequently asked questions
Which threads are included?
6-40 (1/4, 3/8, 1/2in), 6-48 (1/4, 3/8, 9/16in) and 8-40 (1/4, 3/8, 1/2in) in two head styles.
Why Torx instead of slotted?
Six-lobe heads take more torque without the driver slipping and marring the screw or the scope mount.
Does it include drivers?
No. You will need T-10 and T-15 bits; the kit supplies the screws, gauge and tweezers.
