Professional Applications & Engineering Value

This spherical washer addresses critical alignment challenges in heavy machinery, structural steel connections, and industrial equipment where angular compensation is essential. The black-oxide steel material provides superior corrosion resistance while maintaining the Rockwell C48 hardness required for high-stress applications. Engineered with a 3° correction angle, it effectively resolves misalignment issues between bolted components, preventing premature fastener failure and reducing maintenance downtime. The precise 1.75" female ID and 3.250" female OD dimensions ensure perfect fitment with 1 5/8" screw systems, making it ideal for construction, mining equipment, and industrial machinery where vibration resistance and long-term reliability are paramount.

Specification Summary & Compliance

Manufactured to inch system standards with precise dimensional tolerances including thickness (0.673"-0.703"), female ID (1.75"), and female OD (3.250"). The spherical washer meets Rockwell C48 hardness specifications and provides 3° maximum angle correction. Compliant with RoHS 3 (2015/863/EU) under exemption 6(a)-I for lead as an alloying element in steel and REACH (EC 1907/2006) regulations, ensuring environmental responsibility while maintaining industrial performance requirements for heavy-duty applications.
