Square Washer – M12 – Round Hole – 40 x 3.0mm – BZP – Pack of 100
The M12 Square Washer with Round Hole – 40 x 3.0mm is designed to provide a larger bearing surface beneath compatible nuts and fasteners. Its square profile helps distribute tightening loads across a wider area, making it particularly useful where additional load distribution is required.
Measuring 40 x 40mm with a 3.0mm thickness, the washer is suitable for use with compatible M12 fasteners. The increased surface area can help spread clamping forces across the installation material, making square washers particularly useful for timber and construction applications.
A Bright Zinc Plated (BZP) finish provides corrosion resistance and a clean protective finish. This makes the washer a practical fastening component for professional construction, installation and general engineering work.
