Square washers provide a much larger bearing surface than round washers and their square shape prevents rotation when placed against flat surfaces or in tight corners. JLHY's square plate washers are the load-spreading solution for timber and steel construction where maximum bearing area and stability are required.

In timber construction, square washers distribute bolt load across wood grain without concentrating stress on a small circular area — particularly important in large-section timber beams and engineered wood. Produced in carbon steel with hot-dip galvanising for outdoor and ground-contact applications.

Stainless steel A4 square washers are available for marine and coastal timber projects. Standard dimensions per EN 14348 and NBE EA-04. Custom sizes and thicknesses available for engineering requirements.
