Square Plate Washers – Zinc
Zinc square plate washers provide a large clamping surface to spread the load of bolts and fixings in timber and construction applications.
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.
