Timco Form C Washer BS 4320 Bright Zinc Plated M12 18200 g

The Timco Form C Washer BS 4320 is a standard industrial fastener component that complies with the British Standard BS 4320 specification. It is designed to provide a wider outer diameter than Form A or B washers, increasing the effective clamping area under a bolt or nut and helping to distribute load more evenly, thereby reducing surface pressure on softer materials.

Material & Finish

Each washer is forged from robust carbon steel and then plated with a trivalent chromium zinc (Cr³) coating. This bright zinc‑plated finish delivers excellent corrosion resistance and a clean, attractive appearance suitable for applications where durability and aesthetics are required.

Key Benefit

The larger outer diameter improves load distribution, offering a more secure and stable fastening connection, which is especially valuable in demanding industrial assemblies.

Packaging

Washers are supplied in bulk cartons, providing sufficient quantity for large‑scale projects or for maintaining ready stock in workshops and factory environments.
