Washers & Spacers.

Washers & Spacers

What are Washers & Spacers?

Washers can be used for a number of industrial applications. Basic Washers such as Flat Washers can be used for spacing, protection, or for aesthetic purposes. A wide range of specialist Washers are also available:

Shim Washers.

Shim Washers are manufactured in ultra-precise thicknesses, and are designed for highly accurate spacing and very precise height adjustments.

Locking Washers.

Internal Locking Washers are the most common component in this range, and are designed with a circumference of serrated teeth, which lock in place after installation, preventing loosening under vibration. External Locking Washers are also available, as well as Fine Toothed Internal Washers and Fine Toothed External Washers.

Sealing Washers.

Sealing Washers are curved washers which feature a large EPDM rubber seal on their underside. Sealing Washers have a number of uses, but are generally used to create airtight or watertight seals, and are commonly used in roofing applications. 

Captive Washers.

Accu offers a full standard range of Captive Washers. Captive Washers are specially designed for use with Accu's wide range of Captive Screws. A captive fastening locks in place after installation, creating a fastening which can be taken out of a hole, but not fully removed from an installation.


Many of Accu’s Washers can be manufactured from our full range of engineering materials. In addition to corrosion-resistant Stainless Steels, Aluminum, Brass, Phosphor Bronze and the engineering plastic PEEK are available.
