Professional Applications & Engineering Value

These zinc-plated steel flat washers deliver critical engineering value by addressing common industrial challenges such as corrosion-induced failure and uneven load distribution. The zinc plating provides a protective barrier against moisture and chemicals, significantly extending component lifespan in outdoor or high-humidity settings. With a 2" OD and 0.281" ID, they effectively distribute clamping forces over wider areas, preventing surface indentation and maintaining structural integrity in assemblies using 1/4" screws. Ideal for industrial machinery, construction frameworks, and equipment manufacturing, these washers ensure reliable performance while complying with stringent environmental regulations.

Specification Summary & Compliance

This flat washer features a 0.281" inner diameter, 2" outer diameter, and thickness range of 0.042-0.051" for precise fit with 1/4" screw sizes. Manufactured from zinc-plated steel in inch measurements, it adheres to standard dimensional tolerances for consistent performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance in global industrial markets.
