Professional Applications & Engineering Value

This spherical washer addresses critical alignment challenges in heavy machinery, structural steel connections, and precision equipment assembly. The 18-8 Stainless Steel material provides exceptional corrosion resistance while maintaining Rockwell B80 hardness for demanding applications. Engineered with a 3° maximum correction angle, it compensates for angular misalignments between mating surfaces that commonly occur in bolted connections. The inch system dimensions ensure compatibility with North American industrial standards, while the precisely calculated female ID of 0.5" and 1.000" OD create optimal load distribution. This heavy-duty spherical washer solution prevents premature fastener failure, reduces maintenance costs, and extends service life in construction, manufacturing, and marine environments where vibration and dynamic loads are present.

Specification Summary & Compliance

This spherical washer features precise dimensional tolerances with female ID of 0.5" ±0.005", female OD of 1.000" ±0.010", and thickness between 0.297"-0.327". Manufactured from 18-8 Stainless Steel with Rockwell B80 hardness, it's engineered for use with 7/16" fasteners. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring safe use in global industrial applications. The spherical radius of 1.5" provides optimal bearing surface contact while maintaining the specified 3° maximum correction angle for alignment applications.
