Professional Applications & Engineering Value

This precision-engineered spherical washer addresses critical alignment challenges in industrial assemblies where surface irregularities can compromise joint integrity. The 18-8 stainless steel construction provides exceptional corrosion resistance for demanding environments including marine, chemical processing, and outdoor applications. With its 2° correction angle capability, this washer effectively compensates for angular misalignment in structural connections, bolted joints, and machinery mounts. The spherical design ensures uniform load distribution across the bearing surface, preventing localized stress concentrations that can lead to fastener failure. Particularly valuable in applications requiring precise alignment of 5/8 inch fasteners, this component maintains joint integrity while accommodating minor surface variations that commonly occur in welded structures, heavy equipment, and construction applications.

Specification Summary & Compliance

This spherical washer features precise dimensional specifications including 0.656" inner diameter, 1.375" outer diameter, and thickness ranging from 0.298" to 0.328". Manufactured from 18-8 stainless steel with Rockwell B80 hardness, it provides reliable performance for 5/8" fastener applications. The product maintains RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) compliance with current SVHC requirements as of January 17, 2022. Designed for inch system applications, this washer delivers consistent performance with its spherical radius of 1.75" for both male and female configurations, ensuring proper alignment correction in industrial fastening systems.
