Description

Medium Split Lock Washers in Steel with Black Oxide Finish — 7/8" size. Built for strength and reliability, these washers provide secure locking in vibration-prone assemblies.

These steel split lock washers resist loosening by biting into the bolt and nut, maintaining clamping force where it matters most. The black oxide finish adds a corrosion-resistant layer and a clean, professional look for metal hardware projects.

Key Features

  • Material: Steel for dependable durability
  • Finish: Black oxide for enhanced corrosion resistance and a low-profile appearance
  • Size: 7/8" (0.875") — suitable for 7/8" bolt assemblies
  • Locking Action: Split design grips the mating surfaces to reduce loosening from vibration
  • Applications: Ideal for machinery, automotive, and general hardware assemblies

To install, place the washer on the bolt shank and tighten as you would with standard washers to maximize locking performance. Store in a dry environment to help preserve the finish and prolong performance.
