• Precise inch dimensions (0.188" Female ID) ensure reliable compatibility with No. 8 screws for accurate assembly.
• Compatible with replacement male washers for easy integration into existing spherical washer systems and maintenance workflows.
• Complies with RoHS 3 and REACH regulations, ensuring environmental safety and meeting global supply chain requirements.
• Durable steel construction offers long-term reliability in demanding applications like machinery and structural assemblies.

Professional Applications & Engineering Value

This black-oxide steel spherical washer is engineered to solve common alignment issues in industrial settings, where uneven surfaces can lead to fastener failure or assembly inaccuracies. With a maximum correction angle of 3°, it effectively compensates for angular misalignments, distributing load evenly and reducing stress concentrations. The Rockwell C48 hardness ensures it withstands repetitive use and high-pressure conditions, while the corrosion-resistant black-oxide finish protects against rust in humid or outdoor environments. Ideal for applications in machinery, automotive systems, and structural frameworks, this washer enhances assembly precision and longevity, supporting efficient B2B procurement for replacement parts and industrial washers that demand reliability.

Specification Summary & Compliance

This washer features precise inch measurements, including a Female ID of 0.188" and thickness ranging from 0.188" to 0.218", designed for use with No. 8 screw sizes. It adheres to standard dimensional tolerances for inch washers and is manufactured to ensure consistent performance. Compliance includes RoHS 3 (2015/863/EU) with exemption 6(a)-I for lead as an alloying element in steel, and REACH (EC 1907/2006) conformity, affirming its suitability for regulated industrial markets.
