Split lock or helical spring lock washer is a type of lock washer. It is known for having a cylindrical shape with its ends that do not touch. This design allows you to fasten the coil's ends into the screw head, or directly to the fastener's surface. A split lock washer is a great alternative to external teeth washer if you don't want to scratch the screw head or the assembly surface.
