Square Plate Washers
Square plate washers spread bolt load across a much larger area than round washers, and are widely used in timber engineering and structural fixings. We supply plate washers in a range of sizes.
Also known as: square plate washers, square washers, timber construction washers.

The square plate spreads load far beyond a round washer's footprint, suiting timber and thin sheet.
What is a plate washer used for?
Plate washers are large square washers that spread the clamping load of a bolt over soft or weak material - classically timber construction, where a standard round washer would crush into the surface.
What sizes are plate washers available in?
Plate washers are sized by bolt diameter with the plate dimensions and thickness to suit. Send us your requirement and we can identify the appropriate washer.
