Washers for Bolts & Timber Fixings

Shop washers at Clarke Fencing to complete compatible bolted and screwed connections. Our range includes zinc-plated penny washers, mudguard washers and Form A washers in selected sizes.

A washer provides a bearing surface beneath a nut or fixing head and helps distribute the clamping load. This is useful where the fixing would otherwise bear directly on a smaller area of timber or another material.

Choosing a Washer

Compare the washer’s internal diameter, outside diameter and thickness. The hole must accommodate the fixing, while the outer dimensions must suit the available space and required bearing area.

Penny and mudguard washers provide a broad bearing surface relative to their hole size. Form A washers offer another flat-washer option for connections that specify that form and size.

Match the washer’s material and finish to the fastening system and installation environment. Browse our bolts and nuts or coach screws to select compatible components.

Washer FAQs

What size washer do I need?

Choose a washer with a suitable hole size for the fixing. Also check its outside diameter and thickness against the connection requirements.

What are penny washers used for?

Their wider face spreads the load over a larger area than a smaller washer, making them useful where the connection calls for a broader bearing surface.

Will a flat washer stop a nut coming loose?

A flat washer primarily provides a bearing surface and distributes load. Connections requiring resistance to loosening need the appropriate locking arrangement specified for the application.
