About This Product

These serrated flange bolts feature hex heads and include a flanged washer face that possesses serrations on the side that makes contact with the bearing surface. They are intended for use in situations where vibration occurs, as the teeth engage with the surface, requiring greater force to loosen the screw compared to tightening it. In certain applications, the integrated washer removes the necessity for a lock washer or lock nut.
