Timco BS4320B Form B Washer, Bright Zinc Plated, M6, 21.45 kg

The Timco BS4320B Form B Washer is a standardised, industrial‑grade flat washer intended for a broad range of fastening, clamping and spacing tasks. It offers a thinner profile than the Form A design while delivering an excellent bearing surface for nuts and bolt heads, helping to distribute load and protect the clamped material. The washers are manufactured from durable carbon steel, providing the strength required for general‑purpose use, and are engineered to fit standard metric bolts precisely.
