Description

Medium Split Lock Washer in Steel Black Zinc finish, sized for 5/16" fasteners. This washer combines durability with a protective black zinc coating to resist corrosion in tough environments.

Designed to prevent loosening due to vibration, a split lock washer creates a spring effect that bites into the bolt head and substrate, maintaining clamping force and reducing the risk of fastener failure in automotive, machinery, and general hardware applications.

  • Material: High-strength steel with a durable black zinc finish for corrosion resistance.
  • Size: Fits 5/16" fasteners for secure seating.
  • Function: Provides a spring action to resist loosening under vibration.
  • Finish: Black zinc adds corrosion resistance and a clean, professional appearance.
  • Applications: Ideal for automotive, machinery, equipment, and home hardware.

For best results, place the washer between the nut and the contact surface, ensuring it is properly seated and not deformed. Pair with compatible fasteners for optimal performance.
