Professional Applications & Engineering Value
These zinc-plated steel flat washers deliver critical engineering solutions where corrosion resistance and load distribution are paramount. The Grade 5 material strength ensures reliable performance in heavy-duty industrial applications, including machinery assembly, structural steel connections, and automotive frameworks. The precise 0.531" ID x 1.75" OD dimensions, combined with controlled thickness, prevent bolt head embedding and distribute clamping force evenly across surfaces—solving common issues of material deformation and fastener loosening under dynamic loads. Engineered for 1/2" screws in inch-system applications, these washers maintain joint integrity in high-vibration environments, making them ideal for construction, manufacturing, and maintenance operations requiring durable, compliant fastener solutions.
Specification Summary & Compliance
Manufactured to ASME B18.21.1 specifications, these flat washers ensure precise dimensional tolerances for reliable performance with 1/2" screws. The zinc-plated steel construction provides consistent thickness control (0.090-0.112") and surface protection. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms environmental safety and suitability for global industrial supply chains.
