Professional Applications & Engineering Value
This USS flat washer is engineered to solve critical challenges in heavy-duty industrial applications. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, making it suitable for construction, marine, and chemical processing equipment where environmental factors degrade ordinary washers. Its large outer diameter (4.75" OD) effectively distributes high clamping forces over a wider area, preventing joint failure and surface indentation on softer materials. Paired with the precise 2.375" ID for 2 1/4" screw size fasteners, it ensures reliable performance in structural bolting, machinery assembly, and large-scale fabrication, reducing maintenance needs and enhancing the longevity of the entire fastened connection.
Specification Summary & Compliance
This washer conforms to the USS flat washer standard in the inch system with an Inside Diameter of 2.375", Outside Diameter of 4.75", and a Thickness ranging from 0.193" to 0.250". It is manufactured from 18-8 Stainless Steel and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for use in regulated markets.
