Professional Applications & Engineering Value

These Grade 5 zinc-plated steel flat washers deliver critical engineering solutions for industrial assembly challenges. The zinc plating creates a protective barrier against oxidation and chemical exposure, significantly extending component life in manufacturing equipment, structural frameworks, and outdoor installations. With their 1.75" OD and 1.062" ID, these ASME B18.21.1 compliant washers effectively distribute clamping force over wider areas, preventing surface indentation and maintaining bolt pre-load in high-vibration environments. The inch system measurements ensure perfect compatibility with standard 1" screw applications, while the heavy-duty construction withstands repeated stress cycles in mechanical systems, automotive assemblies, and construction projects where reliable fastener performance is non-negotiable.

Specification Summary & Compliance

Manufactured to ASME B18.21.1 standards with precise dimensional tolerances, these flat washers feature a 1.062" inner diameter, 1.75" outer diameter, and thickness range of 0.090-0.112" for consistent performance. The Grade 5 classification ensures mechanical reliability while the zinc-plated steel construction provides durable corrosion protection. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental safety and regulatory adherence for industrial procurement.
