Square Washer

Square Washers provide a larger bearing area than standard round flat washers, making them ideal for connections in timber construction where load distribution and pull-through resistance are particularly important. Available in galvanised and zinc plated finishes, they are commonly used in structural post, beam and framing connections.

Overview

• Square washer range
• Available in galvanised and zinc plated finishes
• Larger bearing surface than standard round flat washers
• Compatible with standard metric bolts, including M12 and other common sizes
• Dimensions noted as bolt size — plate side length — thickness (e.g. M12 – 50x3mm)
• Sold in packs — not as individual pieces

Key Features & Benefits

• Square profile provides greater bearing area to distribute load effectively across timber grain
• Significantly reduces pull-through risk at structural connections, particularly in timber
• Galvanised finish provides corrosion resistance suitable for external applications
• Zinc plated option for internal and protected environments
• Works well with bolts where a larger bearing surface is needed than round washers can provide
• Pack format provides practical supply quantities for builders and contractors

Applications

• Post support and post connection bolt assemblies
• Structural timber-to-timber bolted joints
• Joist hanger and bracket connections in framing
• Decking subframe and outdoor structural connections
• General construction connections where pull-through prevention is important
