Professional Applications & Engineering Value
This black-oxide steel slotted washer delivers critical engineering solutions where corrosion resistance and precise fastening are paramount. The inch-system washers with controlled 0.563" OD and 0.036-0.045" thickness provide consistent spacing and load distribution, preventing joint loosening in vibrating machinery. The 13/64" slot width accommodates standard installation tools while maintaining structural integrity. Particularly valuable in industrial washers applications, the Rockwell B40 hardness ensures the washer maintains its shape under sustained pressure, while the black-oxide finish resists environmental degradation in manufacturing, automotive, and electrical enclosures where No. 10 screw fastening systems require reliable performance.
Specification Summary & Compliance
Manufactured to precise inch measurement standards with 0.563" outer diameter and 0.036-0.045" thickness tolerance. Features 13/64" slot width and 3/8" slot depth compatible with standard installation tools. Constructed from black-oxide steel with Rockwell B40 hardness rating. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in global industrial applications.
