Professional Applications & Engineering Value
This 316 Stainless Steel SAE Flat Washer is engineered to solve critical challenges in corrosive and high-stress environments. The marine-grade 316 stainless steel provides exceptional resistance to saltwater, chemicals, and oxidation, preventing fastener failure in offshore and coastal installations. The integrated acrylic adhesive ensures the washer remains fixed during assembly, eliminating misalignment in automated production lines or hard-to-reach areas. With its 0.039" thickness and Rockwell B70 hardness, it maintains dimensional stability under load, making it ideal for industrial machinery, electrical enclosures, and marine equipment where vibration loosening is a concern. The combination of material excellence and adhesive technology delivers reliable performance in temperature-sensitive applications up to 200°F.
Specification Summary & Compliance
This washer conforms to SAE standards in the inch system with precise dimensions: 0.203" ID x 0.512" OD x 0.039" thickness, designed for No. 10 screw size. Material hardness is certified at Rockwell B70 for consistent mechanical performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and safe for use in regulated industries.
