Choosing flat washers

Use the points below as a practical starting point, then check the individual product page for the full technical information before ordering.

  • Match the washer bore to the bolt or screw diameter so the fastener seats correctly.
  • Check outside diameter and thickness where load spreading or clearance is important.
  • Use a washer material and finish suitable for the environment and mating components.
  • Replace distorted, heavily corroded or damaged washers rather than reusing them in critical joints.
