• Superior corrosion resistance from zinc-plated steel construction, extending service life in harsh industrial environments.
• High-strength performance with Grade 8 classification and Rockwell C38 hardness, ensuring reliability under extreme mechanical stress.
• Precise SAE inch system compatibility for seamless integration with 7/16" fasteners, minimizing assembly errors.
• Consistent dimensional accuracy with thickness ranging 0.051-0.080", providing uniform clamping force and vibration resistance.
• Full regulatory compliance with RoHS 3 and REACH standards, meeting global environmental and safety requirements for industrial procurement.

Professional Applications & Engineering Value

This Grade 8 flat washer delivers critical engineering solutions where high tensile strength and corrosion protection are paramount. The zinc-plated steel material combined with SAE inch dimensions ensures reliable performance in heavy machinery, automotive assemblies, and structural frameworks. Its 0.469" ID perfectly mates with 7/16" bolts, eliminating play and maintaining joint integrity under dynamic loads. The Rockwell C38 hardness prevents deformation under high torque, while the zinc coating fights rust in humid or chemically aggressive settings. Engineers specify this flat washer for applications demanding consistent preload, vibration damping, and long-term durability without frequent maintenance.

Specification Summary & Compliance
