Split-Lock Mechanical Locking Fasteners come in both premium quality 8740 chrome-moly steel 180,000 psi tensile strength with black oxide finish, and rust proof stainless steel with the same unique locking capability. The locking set pin is made from 17-4 ph stainless steel, to prevent corrosion. Both the chrome-moly and stainless steel fasteners have internal and external threads that have been rolled for added strength with a class 2A thread fit. Vibration, heat or torque dependence will not affect its locking ability. Split-Lock Fasteners can be used over and over with the same locking effect.
