This flat support washer provides a stable bearing surface under a fastener. Its 1-1/2-in diameter helps distribute load, maintain spacing, and keep components aligned so hardware stays tight and assemblies operate smoothly. What it does:

  • Distributes clamping force to prevent pull-through and gouging
  • Maintains proper spacing and alignment between mating parts
  • Helps reduce vibration, rubbing, or wobble from a loose assembly
  • Replaces a cracked, deformed, or missing support washer
What's included:
  • One support washer
Install notes:
  • Disconnect power and shut off water/gas before servicing.
  • Note the order and orientation of any washers/spacers during disassembly.
  • Inspect mating hardware and surfaces; replace any worn or damaged parts.
  • Tighten fasteners to manufacturer specifications—do not over-tighten.
