Engineered for dependable fastening in demanding environments, these heavy-duty steel washers help create stronger, longer-lasting bolted connections across construction, engineering, and industrial projects. Designed to sit cleanly under bolt heads and nuts, they spread load evenly to reduce surface damage, minimise stress on fasteners, and help prevent loosening over time—supporting better joint integrity and overall assembly reliability.

Manufactured from durable steel and offered in a choice of protective finishes (including zinc-plated, self-colour, and galvanised options), they deliver excellent resistance to wear and corrosion for both indoor and outdoor applications. Produced to recognised industry standards such as DIN and ISO, they’re a trusted choice for structural steelwork, machinery assembly, maintenance, and heavy-duty installations where consistent performance matters.
