• Reduced maintenance requirements through durable zinc-plated steel construction minimizes replacement frequency

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 that significantly extends component life in humid, outdoor, or chemically exposed environments, addressing common failure points in industrial assemblies. Manufactured to ASME B18.21.1 specifications, these washers provide reliable load distribution for No. 12 screw applications in machinery, electrical enclosures, and structural frameworks. The precisely controlled inner diameter (0.234") and outer diameter (0.438") prevent misalignment issues while the consistent thickness range (0.036-0.045") ensures uniform pressure distribution, eliminating point loading that can compromise joint integrity in mechanical fastening systems.

Specification Summary & Compliance

This flat washer features inch system dimensions with 0.234" inner diameter, 0.438" outer diameter, and 0.036-0.045" thickness range, specifically engineered for No. 12 screw applications. The product conforms to ASME B18.21.1 standard specifications for dimensional accuracy and performance requirements. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility and unrestricted use in regulated markets. The zinc-plated steel construction provides consistent mechanical properties without hardness rating requirements for general industrial applications.
