Washers are generally used for sealing, spacing and distributing the weight of a threaded fastener. Washers can be manufactured to a high degree of accuracy in almost all non-metallic materials. For a comprehensive list of materials we manufacture our range of washers from, please click on the link below.

Also sometimes referred to as spacers, packers or buffers, washers provide numerous fastening solutions to various industrial sectors. Traditionally used within the plumbing industry, washers have since been used not only to solve leakage problems by creating a seal, but more commonly in preventing abrasion and corrosion in construction, lighting, electrical and architectural industries. Buffers are becoming increasingly more popular with aiding in shock absorption and anti vibration applications; whilst spacers and packers are being used in between glass and metal to help prevent chaffing and spread weight distribution evenly.

RH Nuttall Limited has over six thousand individual tool sizes available. New tooling can also be made on request.

Not only do RH Nuttall Limited produce numerous standard sizes of washer, but also manufacture a vast array of unique washers with splines, shaped or notched insides, and/or outsides.

Material thicknesses generally range from 0.2mm up to 12mm. Washers can also be supplied to suit standard M5, M10, M12, M20 bolts or screws. Standard ranges of BSP washers are also readily available. We frequently run one off requirements in conjunction with multi thousand production runs. Furthermore, with our low minimum charge and large material range, coupled with our credit/debit card facility, your washer requirements can normally be supplied both immediately and cost effectively. At RH Nuttall Limited we pride ourselves on an efficient service.

Many of our commonly used materials can be stained for aesthetic or identification purposes. Furthermore, fibre washers can be waxed and non asbestos materials such as Klingersil or Novus can have graphite powder applied.

Materials can be self adhesive backed with a variety of different acrylic tapes, or even laminated to form composites if required.

Certain washers, depending on the base material, can be provided as ‘kiss-cut’ parts. These are adhesive backed washers that are produced on a roll of release paper with the external scrap removed, leaving the washer to be easily peeled away with the adhesive backing still attached to the washer. As removing the paper from adhesive backed parts can cause problems on the assembly line, ask us today to kiss-cut your parts instead. The action of separating the part from its backing is several times faster than the conventional method.
