Built for demanding construction, engineering, and industrial projects, these square and square plate washers deliver secure fastening performance where strength and reliability matter most. Manufactured from high-quality steel and offered in durable protective finishes including zinc-plated (Z/P), self-colour (S/C), and hot-dip galvanised (H.D.GALV), they provide excellent corrosion resistance for long-lasting use in harsh environments.

The square profile increases bearing surface area to help distribute load evenly, reducing bolt stress, minimizing pull-through, and improving the stability of bolted joints. Ideal for structural steelwork, framework assembly, and heavy-duty machinery installations, these washers help maintain fastening integrity under high-load conditions.

Designed to meet relevant industry standards, they’re a dependable choice for trade professionals seeking consistent performance, durability, and secure connections across a wide range of metric fastening applications.
