DIN6796 Conical Spring Washers for Bolted Connections
DIN6796 conical spring washers for bolted connections are critical components used in mechanical joints where bolts are subjected to dynamic loads or vibration. Engineered to maintain clamping pressure and prevent loosening, these washers help extend the life and reliability of bolted assemblies. The DIN 6796 standard governs the dimensions and mechanical properties of these high-performance washers, ensuring consistency and reliability across industrial applications.
At Flybear Fastener, we manufacture premium DIN6796 conical spring washers from high-grade stainless steel with precision-engineered performance for heavy-duty and demanding environments.
Product Overview
Conical spring washers, also known as Belleville washers, are conical-shaped discs that exert a high spring force when compressed. They are designed to support bolt tension retention and mitigate the effects of vibration, thermal expansion, and dynamic load. Our washers are rigorously tested and produced with advanced machinery to guarantee optimal performance aligned with international standards.
These washers are especially effective in assemblies that undergo rapid load reversal, frequent thermal cycles, or significant vibration, making them a staple in both industrial and automotive fastener solutions.
