Professional Applications & Engineering Value
These 18-8 stainless steel flat washers deliver critical performance in demanding applications where corrosion resistance and dimensional precision are paramount. The inch system dimensions (0.328" ID x 0.625" OD) ensure perfect fit with 5/16" fasteners, preventing bolt loosening and distributing clamp load effectively across joined surfaces. Engineers specify these flat washers for machinery assembly, electrical enclosures, marine hardware, and food processing equipment where moisture, chemicals, or temperature variations would degrade ordinary washers. The consistent 0.056-0.070" thickness maintains reliable spacing in stacked components while providing essential vibration resistance in dynamic systems.
Specification Summary & Compliance
This flat washer features precise inch-system dimensions: 0.328" inner diameter, 0.625" outer diameter, and 0.056-0.070" thickness range for consistent performance. Manufactured from 18-8 stainless steel for optimal corrosion resistance and mechanical properties. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring restriction of hazardous substances for global industrial applications.
