The SAE Flat Washer delivers the reliable performance mechanics and auto body shops demand for critical fastening applications. Constructed from 1050 annealed HRPO and hardened to Rc 38/45, this automotive washer resists dishing, bellying, and cracking under heavy loads while distributing pressure evenly across soft materials. The zinc-plated finish with yellow chromate coating provides superior corrosion resistance, ensuring long-lasting durability in harsh automotive environments. With SAE-specified dimensions for a precise fit on standard fasteners, this washer prevents pull-through failures and surface damage while maintaining tight connections that won't loosen under vibration.
