Designed for demanding construction, engineering, and industrial applications, these heavy-duty square washers provide a strong, stable foundation for bolted joints where reliability matters. Manufactured from high-quality steel and available in protective finishes including zinc-plated (Z/P), self-colour (S/C), and hot-dip galvanised (H.D.GALV), they deliver excellent durability and corrosion resistance for indoor and outdoor use.

The square profile offers increased bearing surface to help distribute load evenly, reducing the risk of pull-through and minimising stress on bolts and connected materials. This improves joint stability and fastening integrity, making them a dependable choice for structural steelwork, framework assembly, heavy-duty machinery, and general fabrication.

Built to meet relevant industry standards, these square steel washers are ideal for high-load environments where long-lasting performance is essential—helping you achieve secure, professional fastening results across a wide range of projects.
