• Precise dimensional compatibility with 9/16" screws ensures secure fastening and prevents assembly issues
• Optimized load distribution with 1.156" OD design minimizes surface pressure and prevents material damage
• Reliable performance compliance with ASME B18.21.1 standards guarantees consistent quality and interchangeability
• Environmental regulation adherence with RoHS 3 and REACH compliance for global supply chain compatibility
• Versatile thickness range (0.074-0.121") accommodates various compression requirements and vibration conditions
• Enhanced electrical conductivity of zinc-plated steel provides grounding capability in electrical assemblies

Professional Applications & Engineering Value

This SAE flat washer delivers exceptional engineering value in industrial applications where reliable load distribution and corrosion protection are critical. The zinc-plated steel construction provides a sacrificial layer that actively prevents rust formation, making it ideal for outdoor equipment, automotive assemblies, and machinery exposed to moisture. The precise 0.594" ID ensures perfect alignment with 9/16" screws, eliminating play and maintaining bolt tension under dynamic loads. The generous 1.156" OD creates an optimal bearing surface that prevents embedment in softer materials and distributes clamping forces evenly. These flat washers solve common assembly challenges including surface marring, bolt loosening from vibration, and galvanic corrosion in mixed-material applications.
