Specification:

DIN6927 Prevailing Torque Three-Point Locking Flange Hexagon Nuts are manufactured according to the DIN standard and feature an integrated flange base with a three-point locking design. The flange provides a larger bearing surface to distribute clamping pressure evenly and helps protect the connected parts from damage. The three-point deformation locking system creates prevailing torque, preventing the nut from loosening under vibration and dynamic loads without requiring additional locking elements.
