Professional Applications & Engineering Value

This 7/16" clipped washer is engineered to solve common industrial fastening challenges, such as component loosening due to vibration and surface damage from point loading. Manufactured from 18-8 stainless steel, it offers excellent resistance to rust and chemical corrosion, making it a top choice for applications in marine, chemical processing, and food machinery where moisture and corrosive agents are prevalent. The clipped (external tab) design locks the washer in place against the bolt head or nut, preventing spin-out during torque application and in high-vibration environments. This feature, combined with its heavy-duty thickness and Rockwell B68 hardness, ensures the washer maintains its shape and clamping force, thereby extending the service life of the entire assembly and reducing maintenance frequency.

Specification Summary & Compliance

This washer conforms to standard inch system dimensions with an Inner Diameter of 0.469", Outer Diameter of 1.5", and Thickness ranging from 0.084" to 0.097". The clipped width is specified as 1.265". It is designed for use with 7/16" screw sizes. The product is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and safe for industrial and commercial use.
