Description
13990072 – Wright Flat Washer, Hardened Steel (Genuine Wright OEM Part)
The Wright 13990072 is a genuine OEM flat washer manufactured from hardened steel, designed for high-load fastening applications on compatible Wright lawn and turf equipment. Hardened flat washers are used where increased strength, wear resistance, and consistent load distribution are required—especially in critical structural, drivetrain, and high-torque assemblies.
Manufactured to Wright original equipment specifications, this washer is heat-treated to resist deformation, embedding, and wear under heavy clamping force. Using a genuine Wright hardened washer ensures correct hardness, precise fitment, and long-term fastening reliability in demanding commercial mowing environments.
