Professional Applications & Engineering Value

This 316 stainless steel split lock washer delivers critical vibration resistance in demanding industrial settings where fastener loosening can compromise system integrity. The split lock washer design creates continuous spring tension against both the bearing surface and fastener, effectively preventing rotation and backing-out in high-vibration environments. Manufactured from 316 stainless steel, this washer provides superior corrosion resistance against chemicals, saltwater, and industrial atmospheres, making it ideal for marine applications, chemical processing equipment, and outdoor infrastructure. The ASME B18.21.1 standard compliance ensures dimensional precision and performance reliability, while the substantial 0.375" thickness and Rockwell C35 hardness provide the mechanical strength needed for heavy machinery, structural assemblies, and transportation equipment where vibration resistant washers are essential for operational safety.
