Professional Applications & Engineering Value
These 1/4" flat washers made from 18-8 stainless steel address common industrial challenges like corrosion-induced failure and inconsistent load bearing. The flat washer design evenly distributes clamping force, preventing surface indentation and bolt loosening in vibrating equipment. With a Rockwell B83 hardness, they maintain integrity in high-torque applications, while the precise 0.281" ID and 0.625" OD ensure compatibility with standard 1/4" screws. Ideal for industrial washers in marine, chemical, and outdoor settings, their corrosion-resistant properties reduce maintenance costs and downtime, delivering long-term engineering value.
Specification Summary & Compliance
This flat washer adheres to inch system measurements with an inner diameter of 0.281", outer diameter of 0.625", and thickness ranging from 0.168" to 0.193", designed for screw size 1/4". Manufactured from 18-8 stainless steel with a hardness of Rockwell B83, it meets industry standards for dimensional accuracy. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance in professional applications.
