Serrated Flange Lock Nut, Plated

Case hardened serrated flange lock nuts eliminate the need for a lock washer or washer, as the flange serves to distribute the bearing load over a greater area. The bearing surface has circular serrations that fan out so that once the serrated flange makes contact with the mating surface, the serrations cut into and displace the mating material upon tightening. All metal lock nuts are resistant to high temperatures and high chemical exposures, as they are made from one material. Dimensional specifications are governed by ASME B18.16.4. Available in zinc plated finish. Zinc plating sacrifices itself, corroding before the base material, offering added corrosion resistance.
