Square Plate Washers – Hot Dipped Galvanised

About Hot Dipped Galvanised Square Plate Washers

Hot dipped galvanised square plate washers are designed to provide a large surface area that helps spread the clamping load of a bolt or fixing. Their square shape offers greater load distribution than standard round washers, making them suitable for structural and heavy-duty applications.

These washers are commonly used in timber construction, structural bolting and steelwork where additional support is required under the bolt head or nut.

Typical Applications

• Structural timber connections
• Steel and timber construction
• Spreading the load of large bolts
• Heavy duty fixing assemblies

Hot Dipped Galvanised Finish

Hot dipped galvanising provides a thick protective zinc coating that helps protect the washer from corrosion. This makes galvanised square plate washers suitable for outdoor environments and structural applications where durability is important.

Available Sizes

Square plate washers are available in sizes designed to suit common structural bolt diameters.

What Is The Difference Between Hot Dipped and Galvanised Washers?

Hot dipped galvanised washers are coated by immersing the steel in molten zinc, creating a thicker protective coating. This process provides improved corrosion resistance compared with standard zinc plated washers, making them suitable for outdoor and structural applications.
