This high-performance thru-hardened washer is engineered for demanding applications where secure, high-strength bolted connections are essential. Manufactured from quality through-hardened steel, it delivers excellent load distribution and long-lasting durability, helping to minimise the risk of loosening under vibration, dynamic loads, or extreme pressures. The precision manufacturing process ensures tight tolerances and a consistent, reliable fit, making it ideal for both professional and industrial use. Its robust construction supports structural integrity in critical joints, providing a dependable fastening solution in even the most challenging environments.

Featuring a corrosion-resistant surface treatment such as zinc-plated (Z/P), sherardized, self-colour (S/C), or galvanised (GALV), this washer is well suited to construction, steel fabrication, infrastructure projects, mechanical assemblies, and heavy engineering. Designed to meet key industry standards, including DIN 6916, EN14399-6, and ISO 7090, it offers full compatibility with high-strength structural fasteners and HSFG bolt assemblies. The combination of thru-hardening, protective coating options, and compliance with recognised specifications ensures optimal performance, safety, and longevity in service. Whether used in large-scale structural frameworks or everyday industrial installations, this washer provides a secure, stable, and efficient reinforcement to bolted joints, making it a trusted choice for engineers, fabricators, and maintenance professionals seeking reliable fastening components.
