These high-strength load indicating washers are designed for maximum security in critical fastening applications where accurate bolt tension and long-term reliability matter. Manufactured from top-grade stainless steel (ST/ST) or protected with Delta Protekt zinc coatings, they offer excellent corrosion resistance and durability for demanding indoor and outdoor environments.

Featuring a wedge lock mechanism, they deliver superior resistance to loosening caused by vibration and dynamic loads—helping maintain clamp force in structural and heavy-duty assemblies. The integrated load-indicating function provides real-time feedback on bolt tension during installation, supporting precise tightening, improved safety, and consistent performance across bolted joints.

Built to meet recognised industry standards including DIN 6797/98 and EN14399-9, these washers are well-suited to industrial, construction, and engineering projects where compliant, precision fastening is essential. Ideal for use with high-strength fastener systems, they help reduce maintenance, increase joint integrity, and support dependable installation outcomes.
