Key Features & Benefits at a Glance
- 5° maximum angle correction compensates for misalignment, reducing stress on fasteners and extending assembly life
- Black-oxide steel construction provides excellent corrosion resistance and durability in demanding industrial environments
- Rockwell C25 hardness ensures superior wear resistance and maintains structural integrity under high loads
- Precision inch dimensions (0.625" OD, 0.281" ID) guarantee perfect fit with 1/4" screws for reliable installations
- Spherical bearing design allows smooth articulation, preventing binding and ensuring even load distribution
- Compatible with replacement male washers for versatile system integration and maintenance flexibility
- Heavy-duty thickness (0.173"-0.203") provides robust support for high-stress applications
Professional Applications & Engineering Value
These spherical washers solve critical alignment challenges in industrial applications where surface irregularities cause fastener stress. The black-oxide steel material with Rockwell C25 hardness withstands harsh conditions while the spherical radius design (0.75") enables ±5° angular correction - eliminating the need for precise machining of contact surfaces. This precision washer design is particularly valuable in heavy machinery, structural steel connections, and automotive assemblies where misalignment compensation directly impacts assembly reliability and reduces maintenance costs. The 0.625" OD and 0.281" ID dimensions ensure compatibility with standard 1/4" screw systems while providing maximum bearing surface.
Specification Summary & Compliance
Manufactured to inch system specifications with precise dimensional control: Female/Male ID 0.281", OD 0.625", thickness 0.173"-0.203", and 0.75" radius. These spherical washers meet industry standards for alignment components and maintain Rockwell C25 hardness throughout. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility and global market acceptance for industrial applications.
