Washers

Our Range of Washers

Our washer range includes several types designed for different fixing applications. From standard flat washers used in general assembly to heavy-duty washers designed for structural connections, each washer type helps spread load and support the fixing.

The range includes Form A, Form B and Form C washers, penny repair washers for large load spreading, spring washers for preventing loosening and square plate washers for structural fixing applications.

Washer Finishes and Corrosion Protection

Washers are available in different finishes depending on the environment where they will be used. Choosing the correct finish helps protect the fixing from corrosion and improves durability.

Finish	Corrosion Resistance	Typical Applications
Zinc Plated	Light corrosion protection	Clean, dry indoor environments
Hot Dipped Galvanised	High corrosion resistance	Outdoor and structural applications
Stainless Steel	Excellent corrosion resistance	Outdoor, marine or corrosive environments

Types of Washers

Several different washer types are used in construction and engineering applications. The most common include standard flat washers, load spreading washers and locking washers.

Washer Type	Typical Use
Form A Washers	General purpose flat washers used with bolts and screws to spread load and protect surfaces.
Form B Washers	Flat washers with a larger outer diameter for increased load distribution.
Form C Washers	Extra wide washers designed to spread clamping force over a larger surface area.
Penny Repair Washers	Large diameter washers used to repair oversized holes and support thin materials.
Spring Washers	Split washers designed to help prevent nuts and bolts loosening due to vibration.
Square Plate Washers	Heavy-duty washers that spread load across structural timber and steel fixings.

Choosing the Right Washer

The correct washer depends on the fixing application. Standard flat washers are suitable for general fixing, while penny washers and square plate washers provide additional load distribution. Spring washers are commonly used where preventing loosening due to vibration is important.

What Are Washers Used For?

Washers are small metal components placed between a bolt or screw head and the surface being fixed. Their main purpose is to distribute the clamping force of the fixing, helping prevent damage to the material and improving the security of the joint.

Different types of washers are designed for different applications. Some washers spread load across a wider area, while others help prevent nuts and bolts from loosening due to vibration.
