Professional Applications & Engineering Value
These zinc-plated steel flat washers deliver critical engineering solutions for industrial assembly and maintenance operations. The corrosion-resistant zinc plating protects against environmental degradation in outdoor equipment, manufacturing facilities, and marine-adjacent applications. With precise 0.656" ID x 1.75" OD dimensions specifically engineered for 5/8" screws, these washers prevent bolt loosening from vibration while distributing clamp load evenly across surfaces. The ASME B18.21.1 compliance ensures consistent performance in structural connections, machinery assembly, and heavy equipment maintenance where reliable load distribution is essential for operational safety and equipment longevity.
Specification Summary & Compliance
Manufactured to ASME B18.21.1 specifications with dimensional accuracy of 0.656" inner diameter, 1.75" outer diameter, and thickness range of 0.090-0.112". Constructed from zinc-plated steel for optimal performance. Fully compliant with RoHS 3 (2015/863/EU) with exemption 6(a) for lead as an alloying element in steel and REACH (EC 1907/2006) regulations (01/17/2023, 233 SVHC) for environmental safety and industrial use.
