SPECIFICATIONS
An all-metal, one-piece, hex-shaped lock nut with a round collar at its back end. The collar is segmented with opposed slots cut into it above each corner of the nut. When the screw or bolt reaches the collar, the slotted portion expands which creates the prevailing torque locking action. The thin height light Hex flexible lock nut is used when an insufficient number of projecting threads are present to use a full height nut, or when a lighter weight nut is required. The light Hex variety has a lesser across the flats dimension resulting in a lighter weight part with the same strength as a heavy Hex variety.
