Professional Applications & Engineering Value

These zinc-plated steel flat washers deliver critical engineering solutions by preventing fastener loosening and surface damage in industrial assemblies. The precision-grade dimensions (0.594" ID x 1.125" OD) ensure perfect alignment with 9/16" screws, distributing clamp load evenly to prevent joint failure. The zinc plating creates a sacrificial barrier against oxidation, making these flat washers ideal for applications exposed to moisture, chemicals, or outdoor conditions. Manufacturing facilities, construction projects, and equipment maintenance operations benefit from the ASME B18.21.1 certification, which guarantees consistent performance across batch productions and replacement scenarios.

Specification Summary & Compliance

Manufactured to ASME B18.21.1 dimensional standards with inch system measurements: 0.594" inner diameter, 1.125" outer diameter, and 0.056-0.071" thickness range. Full compliance with RoHS 3 (2015/863/EU) under exemption 6(a) for lead as steel alloying element and REACH (EC 1907/2006) regulations (233 SVHC as of 01/17/2023). Designed specifically for use with 9/16" screws in mechanical fastening applications requiring reliable load distribution and surface protection.
