Square Plate Washers – Zinc

About Zinc Square Plate Washers

Zinc square plate washers are designed to provide a large surface area under a bolt head or nut, helping spread the clamping load across a wider section of material. The square shape provides greater load distribution than standard round washers.

These washers are commonly used in timber construction and general fixing applications where additional support is required under the fastening.

Typical Applications

• Timber construction fixings
• Spreading the load of bolts and threaded fixings
• Supporting structural connections
• General construction and repair work

Zinc Plated Finish

These washers are zinc plated (CR3) and passivated (3–5 microns), providing light corrosion resistance. They are suitable for clean, dry environments and general internal applications.

Available Sizes

Square plate washers are available in a range of sizes to suit common bolt diameters used in timber and structural fixing applications.
