Professional Applications & Engineering Value

This 3/8" spherical washer addresses critical alignment challenges in industrial machinery, structural steel connections, and heavy equipment where surface irregularities can compromise joint integrity. The 18-8 stainless steel composition provides inherent corrosion resistance for applications exposed to moisture, chemicals, or outdoor elements. The spherical design allows the washer to pivot up to 3°, distributing load evenly across uneven surfaces and preventing localized stress that could lead to fastener loosening or material fatigue. With Rockwell B80 hardness, these washers maintain their structural integrity under repeated loading cycles, making them suitable for precision alignment in construction, automotive, and manufacturing applications where vibration resistance and long-term reliability are paramount.

Specification Summary & Compliance

Manufactured to precise dimensional specifications including Female ID: 0.406", Male ID: 0.386", and thickness range: 0.407"-0.438". The spherical washer meets industry standards for inch system fasteners and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations. Designed specifically for use with 3/8" screws, this washer provides reliable performance in applications requiring angular correction while maintaining environmental and safety standards.
