Professional Applications & Engineering Value
This USS flat washer in 18-8 stainless steel delivers critical engineering value by solving common industrial fastening challenges. Its corrosion-resistant properties make it ideal for outdoor machinery, chemical processing equipment, and marine applications where moisture and corrosive agents degrade ordinary washers. The precise 0.625" ID ensures a snug fit on 9/16" screws, eliminating play that can lead to vibration-induced failures. With a 1.5" OD, it effectively distributes clamping force over a wider area, protecting soft surfaces and maintaining bolt preload in heavy-duty assemblies. Engineers specify this washer to extend equipment lifespan and reduce maintenance frequency in demanding operational environments.
Specification Summary & Compliance
This washer conforms to USS flat washer standards in the inch measurement system, with precise dimensions: 0.625" ID, 1.5" OD, and thickness ranging 0.086-0.132". Material hardness is certified at Rockwell B68 for consistent mechanical performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, including the latest SVHC updates, ensuring environmental safety and unrestricted industrial use.
