Rail Screw


Our Peak cross bolts are CNC machined in the USA from 4140 Heat Treated CroMoly steel, and finished in corrosion resistant Black Oxide.

Each screw has a Nylok® Torq-Patch® applied to the threads. Nylok® Torq-Patch® is a self-locking nylon permanently bonded onto the threads that resists vibration loosening. Since nylon has great memory characteristics, this locking element can be reused several times.

Peak cross bolts are sold in singles and are designed and made specifically to fit precisely in our Peak Fixed iron sights.
