These 5/16 in. split lock washers are designed for maintenance, assembly, and fastening work where threaded fasteners may rotate or lose friction. They help provide resistance to vibration-related loosening in general-purpose, marine, and corrosive-environment applications.

Forged from 18-8 stainless steel, each washer has a trapezoidal cross section that deflects under load. The washers may be used alone or with a stainless steel flat washer and are covered by ASME B18.21.1. This pack contains 100 split lock washers sized for 5/16 in. fasteners.


Key Features:

  • 18-8 stainless steel: Provides corrosion and chemical resistance for use in demanding environments.
  • Trapezoidal split design: Deflects under load to help resist fastener loosening from vibration.
  • 5/16 in. size: Matches compatible 5/16 in. threaded fasteners.
  • 100-piece pack: Supplies multiple washers for assembly and maintenance tasks.
  • Flat washer compatible: Can be installed with or without a stainless steel flat washer.

Choose these 5/16 in. stainless steel split lock washers when your fastening work calls for vibration-loosening resistance and compatibility with stainless steel flat washers.
