Frequently asked

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.
