Professional Applications & Engineering Value
These zinc-plated steel flat washers deliver critical engineering solutions where corrosion resistance and dimensional precision are paramount. The zinc plating creates a protective barrier against moisture and chemicals, significantly extending component life in harsh industrial environments. Manufactured to ASME B18.21.1 standards, these flat washers provide reliable load distribution and surface protection for No. 2 screw applications in electrical enclosures, machinery assembly, and automotive components. The controlled thickness tolerance (0.028-0.036") ensures consistent performance while preventing joint loosening and material deformation under vibration and thermal cycling conditions.
Specification Summary & Compliance
This flat washer features precise inch dimensions with 0.094" internal diameter and 0.344" outer diameter, manufactured to ASME B18.21.1 specifications for dimensional accuracy and performance reliability. The product demonstrates full compliance with RoHS 3 (2015/863/EU) under exemption 6(a) for lead as an alloying element in steel and meets REACH (EC 1907/2006) requirements regarding Substance of Very High Concern (SVHC) as of January 17, 2023. The Rockwell B40 hardness rating ensures consistent mechanical properties across production batches.
