FIELD: machine building.
SUBSTANCE: this invention relates to grounding nut, in which conductivity state between said nut and bolt can be achieved. Grounding nut, having threaded hole, interacting with bolt, on which screw thread is made with pitch P, wherein for all thread turns, made in threaded hole, thread pitch Pn exceeds bolt thread pitch P, and thread profile angle θ is more than 60 degrees, and on part of threaded hole cutout is made in axial direction, passing in axial direction, wherein screw thread end surface, facing to said cutout is made in form of cutting edge.
EFFECT: this allows to enable conductivity by removing coating film from bolt.
