Rubber Washers

Below is our standard range of Rubber Washers.

A Washer distributes the pressure of the nut evenly over the surface to prevent damage to the surface or to ensure the nut presses against a smooth surface to reduce the chance it will gradually loosen. We keep a selection of moulded and punched rubber washers in stock.

  • Same day despatch on stock items.
  • 5 - 7 working days average lead time for made to order standard parts.
  • Minimum order value of £30 (plus carriage and VAT - subject to stock)
  • Some parts may be subject to minimum order quantities should they not be in stock.
