Timco BS4320B Form B Washer, Bright Zinc Plated, M8, 19.1 kg

The Timco BS4320B Form B Washer is an industrial‑grade flat washer designed for a wide range of fastening, clamping and spacing duties.

Key Applications

• Provides a stable bearing surface beneath nuts and bolt heads.
• Distributes clamping force over a larger area to protect softer substrates.
