Professional Applications & Engineering Value
These 18-8 stainless steel flat washers are engineered to address common industrial challenges such as galvanic corrosion, vibration-induced loosening, and surface damage. The corrosion-resistant alloy provides reliable performance in marine, chemical processing, and outdoor applications, preventing fastener failure. With precise inch-system dimensions (0.375" ID x 0.75" OD) and a controlled thickness range, they ensure uniform clamping force and protect surfaces from abrasion when used with No. 20 screws. This makes them indispensable in assembly lines, automotive manufacturing, and structural frameworks where durability and environmental compliance are critical.
Specification Summary & Compliance
This flat washer adheres to standard inch measurement tolerances, with an inner diameter of 0.375", outer diameter of 0.75", and thickness between 0.043-0.057". It is manufactured from 18-8 stainless steel with a hardness of Rockwell B68, ensuring mechanical reliability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for use in environmentally conscious and regulated industrial sectors.
