Specification:
DIN980V Prevailing Torque Three-Point Locking Hexagon Nuts are a type of all-metal self-locking nut manufactured according to DIN standards. Unlike nylon insert lock nuts, these nuts achieve reliable locking performance through three-point metal deformation on the bearing face, creating prevailing torque and preventing loosening caused by vibration or dynamic loads. The hexagonal design allows easy installation with standard tools, while the all-metal construction provides excellent temperature resistance and durability in demanding environments.
