Abstract

PURPOSE: To prevent the nut from turning together with the bolt when it is fastened by containing an arbitrary-shaped member made of hard material with a part of it protruding out of the seat surface in a recess arranged on the seat surface of the bolt. CONSTITUTION: A recess 2 arranged on the seat surface 1 of the bolt contains a hard member 3. The hard member 3 has a HRC of e.g. over 60, and a part of it protrudes out of the seat surface 1. When a nut is inserted from the opposite side of the seat surface 1 and fastened by a spanner or the like, all the axial fastening load generated by the turning of the nut is applied to the extremity of the protrusion, which contacts the counterpart seat surface in a point contact way and bites into it at last. Therefore it is possible to prevent the nut from turning together with the bolt when it is fastened.
