なかに収容される。(Prior Art and Problems to be Solved) West German Utility Model No. 8417373 discloses a collar nut with a bore that is screwed into a threaded stud covered with a hard coating. The bore has a generally conical cross-section and is provided with a projection extending in a direction towards the axis of the weld stud for removing the coating during the screwing operation. The coating that has come off during the screwing operation is accommodated in this nut by means of a conical section or a cutout specifically provided for this purpose.

え、特に自動工具による組み立てに有効である。(Effects of the invention) The collar nut according to the invention has the advantage that the coating peeled off by the sharp edges can be cleanly removed outward along the curved groove. By this method, it is possible to prevent particles of the peeled coating from getting between the contact surface of the nut and the object held by the stud, and it also allows the nut to be firmly screwed in. I can do it. Therefore, according to the present invention, a friction coefficient can be ensured with good reproducibility between the contact surface and the object, and reliability can be improved. Therefore, it is particularly useful for assembly using automatic tools.
第１項のカラーナツトにおいて、好ましくは、
該溝は接触平面の外側エツジにおいて開放されて
いる。これによつて、材料を容易に道の外に排掃
することができる。 In the color nut of item 1, preferably,
The groove is open at the outer edge of the contact plane. This allows material to be easily swept out of the way.

けるナツトの接触平面３の間から排掃される。(Description of Embodiments) FIG. 1 shows an example of a collar nut 1 according to the present invention having grooves of approximately uniform width. The nut 1
has a smooth central bore 2 and a circular contact surface 3. An inclined surface 4 is provided on the outer periphery of the circular contact plane 3. The circular contact plane 3 and the inclined surface 4 are provided with six curved grooves 5 of approximately uniform width. The web 7 remaining between the grooves 5 has sharp edges 6 which are intended to peel off the thick hard layer on the threaded stud during the screwing process. The material separated during the screwing process is guided outward through the groove,
The groove is then swept out between the contact surfaces 3 of the nut in the region of the open slope 4.
