Professional Applications & Engineering Value
These 316 stainless steel flat washers are engineered to address critical challenges in corrosive and demanding settings. The marine-grade 316 alloy provides exceptional resistance to saltwater, chemicals, and oxidation, preventing fastener failure in industrial and offshore applications. With precise inch-system dimensions (0.125" ID x 0.625" OD) and a uniform thickness range, they ensure even pressure distribution under No. 4 screw heads, reducing surface damage and loosening risks. This design is vital for maintaining joint integrity in vibrating machinery, plumbing systems, and marine equipment, where reliability is non-negotiable. The flat washer profile simplifies installation while enhancing the lifespan of connected components.
Specification Summary & Compliance
This washer meets standard inch-system dimensional tolerances with an inner diameter of 0.125", outer diameter of 0.625", and thickness between 0.039" and 0.052", designed specifically for No. 4 screw size applications. It is manufactured from 316 stainless steel and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, affirming its suitability for environmentally conscious and regulated industrial uses.
