Professional Applications & Engineering Value
This spherical washer is engineered to solve common alignment issues in industrial assemblies, such as misaligned bolted connections that lead to premature wear and failure. Made from black-oxide steel, it offers enhanced corrosion protection, making it ideal for outdoor machinery, automotive systems, and heavy equipment exposed to moisture. The 3° correction angle accommodates angular deviations, ensuring uniform load distribution and reducing the risk of loosening. With a Rockwell C48 hardness, it withstands repetitive stresses in high-vibration applications, providing long-term reliability. Its precise dimensions, including a 0.219" female ID, ensure compatibility with No. 10 screws, streamlining installation in industrial washers and alignment-critical setups.
Specification Summary & Compliance
This washer features a female ID of 0.219", female OD of 0.438", and thickness between 0.219"-0.249", adhering to standard inch system tolerances for precise fit. It complies with RoHS 3 (2015/863/EU) under exemption 6(a)-I for lead in steel and REACH (EC 1907/2006) as of 01/17/2023, ensuring environmental and safety standards are met for industrial use.
