Professional Applications & Engineering Value

This 18-8 stainless steel clipped washer is engineered to address common industrial fastening challenges, such as vibration loosening and corrosion-induced failure. Its clipped design provides a positive locking mechanism that prevents the washer from spinning during torque application, ensuring consistent clamping force in machinery, automotive, and electrical enclosures. The corrosion-resistant properties of 18-8 stainless steel make it suitable for demanding environments, including marine, chemical processing, and food-grade equipment, where moisture and chemicals are prevalent. By combining precise dimensions (0.281" ID for 1/4" screws) with high hardness (Rockwell B68), this washer delivers reliable performance in industrial applications, reducing maintenance needs and enhancing the longevity of assembled components.

Specification Summary & Compliance

This clipped washer adheres to inch system measurements with an inner diameter of 0.281", outer diameter of 0.75", thickness range of 0.056-0.071", and clipped width of 0.609", designed specifically for 1/4" screw sizes. Manufactured from 18-8 stainless steel with a Rockwell B68 hardness rating, it ensures dimensional precision and mechanical strength. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its safety and environmental standards for global industrial use.
