When standard washers flatten out and fail under pressure, Heavy-Duty DIN 6796 Disc Springs keep your critical bolted connections locked down tight. Engineered specifically for high-strength bolted joints, these conical washers act as powerful disc springs to counteract the devastating effects of bolt stretch, relaxation, and thermal expansion.

Why Leading Engineers Specify DIN 6796:

• Unmatched Preload Retention: Delivers high spring force to maintain constant tension, effectively preventing loosening caused by heavy vibration or dynamic loads.
• Heavy-Duty Construction: Manufactured from premium carbon spring steel and stainless steel, built to withstand extreme mechanical stress.
• Thermal Shock Resistant: Ideal for high-temperature environments where metals expand and contract, ensuring your joints remain secure.
• Optimized for High-Tensile Bolts: Perfect for use with property class 8.8 and 10.9 bolted connections.

Perfect For: Heavy machinery, automotive assemblies, structural steelwork, electrical power distribution, and high-vibration industrial equipment.
