Professional Applications & Engineering Value

These USS flat washers deliver exceptional engineering value through their black corrosion-resistant coated steel construction, specifically engineered to combat rust and degradation in demanding industrial environments. The precise dimensional specifications - including the 1.75" OD and 0.688" ID - ensure perfect compatibility with 5/8" screw applications, preventing loosening and maintaining bolt tension under vibration and dynamic loads. The flat washer design effectively distributes clamping force across a wider surface area, protecting sensitive materials from damage while preventing fastener embedment. Ideal for construction, heavy machinery, and outdoor equipment applications, these industrial washers provide reliable performance where corrosion resistance and dimensional accuracy are critical to assembly integrity and longevity.

Specification Summary & Compliance

Manufactured to exacting ASME B18.21.1 standards, these USS flat washers guarantee dimensional precision and interchangeability within the inch system of measurement. The product features an inner diameter of 0.688", outer diameter of 1.75", and thickness ranging from 0.108" to 0.160" specifically engineered for 5/8" screw sizes. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility and workplace safety, making these washers suitable for global industrial applications requiring strict regulatory adherence.
