Square Washers

Square washers are flat washers with four straight sides. They spread the load over a wide area and are widely used with cup square bolts and coach screws in timber, and over slotted or oversize holes.

Our range runs from M6 to M30, zinc plated, bare or hot dip galvanised.

Choose hot dip galvanised for outdoor timber work. See Mild Steel Cup Square Bolts.
