FIELD: transport. ^ SUBSTANCE: invention relates to machine building and may be used to facilitate assembling, mounting and locking automotive components of cars and trucks. Proposed holder comprises thread, cylindrical flange, hexagon and guide section. Guide chamfered rod section is made ahead of thread. Note here that rod part diameter equal or is smaller than thread ID. Tapered section is made between hexagon and cylindrical flange to converge toward said hexagon. Diameter of hexagon circumscribed circle exceeds that of thread, while guide section, ahead of hexagon, is formed by two conjugate radii. ^ EFFECT: ease of fabrication and mounting, improved operating performances. ^ 1 dwg |
