SAE Flat Washer Thru-Hardened Steel 5/16"
(Pack of
100)
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.
