Professional Applications & Engineering Value
These zinc-plated steel flat washers deliver critical engineering solutions where corrosion resistance and dimensional precision are paramount. The Rockwell B40 hardness ensures consistent performance in vibration-prone assemblies, while the ASME B18.21.1 compliance guarantees reliable fit with No. 2 screws across industrial equipment, electrical enclosures, and machinery components. The zinc plating creates a sacrificial layer that significantly extends service life in humid or chemically aggressive environments, reducing maintenance frequency and replacement costs. Their inch-system dimensions make them ideal for North American manufacturing and repair applications requiring standardized flat washers with certified quality assurance.
Specification Summary & Compliance
Manufactured to ASME B18.21.1 dimensional standards with precise inch-system tolerances: 0.094" ID, 0.188" OD, and 0.022-0.028" thickness range. The zinc-plated steel construction meets Rockwell B40 hardness requirements for mechanical durability. Full compliance with RoHS 3 (2015/863/EU) under exemption 6(a) and REACH (EC 1907/2006) regulations (including 233 SVHCs as of 01/17/2023) ensures environmental responsibility and global market accessibility.
