Split Lock Washers

  • Black-oxide steel washers are mildly corrosion resistant in dry environments.
  • 316 stainless steel washers have excellent resistance to chemicals and salt water. They may be mildly magnetic.
  • 18-8 stainless steel washers have good chemical resistance and may be mildly magnetic.
  • Zinc- and zinc yellow-chromate plated steel washers are corrosion resistant in wet environments.
  • Hot-dipped galvanized steel washers are 10 times as corrosion resistant as zinc- and zinc yellow-chromate plated washers.

As the screw is tightened, these washers flatten to add tension to the joint and prevent loosening from small amounts of vibration.
