Professional Applications & Engineering Value
Engineered for high-corrosion resistance, these 316 stainless steel flat washers address critical failure points in industrial settings, such as marine, chemical processing, and outdoor infrastructure. The inch-system design with precise inner and outer diameters ensures optimal load spreading, reducing stress concentration on connected surfaces. This flat washer type, combined with Rockwell B68 hardness, resists deformation under heavy loads and vibrations, extending the lifespan of assemblies using No. 8 screw sizes. By integrating RoHS 3 and REACH compliance, these washers meet stringent environmental regulations, making them a reliable choice for industrial applications requiring durability and safety.
Specification Summary & Compliance
This flat washer adheres to inch-system dimensional standards with an ID of 0.188", OD of 0.438", and thickness range of 0.050-0.080" for precise fit. It is manufactured to meet Rockwell B68 hardness specifications, ensuring consistent mechanical performance. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards, confirming the absence of restricted substances for industrial safety and environmental protection.
