- Black-oxide steel construction provides excellent corrosion resistance and durability in harsh industrial environments
- Rockwell C48 hardness rating ensures superior wear resistance and maintains structural integrity under heavy loads
- Precision-engineered thickness (0.312"-0.344") delivers consistent performance and reliable load distribution
- Compatible with 5/16" screw sizes offers versatile application across various industrial fastening systems
- Full regulatory compliance meets RoHS 3 and REACH standards for safe use in regulated industries
- Spherical design with male/female pairing enables smooth articulation and prevents binding in dynamic applications
Professional Applications & Engineering Value
These spherical washers solve critical alignment challenges in heavy machinery, construction equipment, and automotive assemblies where surface irregularities cause fastener stress. The black-oxide steel surface treatment provides corrosion protection while maintaining the Rockwell C48 hardness needed for high-load applications. The spherical mating surfaces allow ±3° angular adjustment, preventing premature wear in misaligned joints and extending component lifespan. Engineers specify these precision washers for pivot points, structural connections, and equipment requiring reliable angular correction without compromising fastener integrity.
Specification Summary & Compliance
Manufactured to inch system standards with precise dimensional control: Female ID 0.344", Male ID 0.323", and consistent 0.312"-0.344" thickness. The spherical radius of 0.063" ensures proper articulation. Compliant with RoHS 3 (2015/863/EU) under exemption 6(a)-I and REACH (EC 1907/2006) regulations, guaranteeing material safety and environmental responsibility. The Rockwell C48 hardness specification confirms consistent heat treatment and mechanical properties for industrial-grade performance.
