DIN 980V All Metal Lock Nut

a). Prevailing torque type hexagon nuts feature a design where increased friction within the threads prevents the nut from loosening on its own. This friction is generated by the prevailing torque element integrated into the nut, which induces axial and/or radial clamping in the bolted connection.

b). DIN 980 (Type V) prevailing torque type hexagon nuts. Single-piece metal nut without an insert, in which increased friction is generated through the deliberate deformation of the prevailing toruqe element of the nut.
