In order to realize the above-mentioned purpose, the utility model provides an outer hexagon bolt of adaptation unevenness installation face, including outer hexagon bolt head, screw rod section, polished rod section, spacing bulge loop, the fastening lantern ring, screw rod section top is provided with the polished rod section, the polished rod section radially is provided with spacing bulge loop with the junction of screw rod section, the lateral surface of spacing bulge loop is the protruding arc surface, the outside cover of spacing bulge loop is equipped with the fastening lantern ring, the medial surface of the fastening lantern ring is the concave arc surface, concave arc surface and protruding arc surface form a complete set interlock of each other, outer hexagon bolt head sets up the top at the polished rod section.
Preferably, the outer hexagonal bolt head, the screw rod section, the polished rod section and the limiting convex ring are of an integrated structure.
Preferably, the axial lines of the outer hexagonal bolt head, the screw rod section, the polished rod section and the limiting convex ring are positioned on the same straight line.
Preferably, the concave arc surface and the convex arc surface are both smooth arc surfaces, and the inner diameter of the concave arc surface is the same as the outer diameter of the convex arc surface.
Preferably, the thickness of the limiting convex ring is two thirds of that of the fastening collar.
Preferably, the bottom end of the screw section is provided with a conical lead-in section with threads.
Preferably, the screw section and the polish rod section have the same diameter, and the opening diameter of the fastening collar is larger than that of the screw section.
Preferably, the bottom of the fastening lantern ring is uniformly provided with a plurality of anti-skid protrusions.
The utility model has the advantages that: the utility model discloses a combine outer hexagon bolt head, screw rod section, polished rod section, spacing bulge loop, adapter sleeve ring to be in the same place, through experimental optimization, when can making bolt and screw hole cooperation installation, the fastening installation face of bolt fastening position self-adaptation unevenness need not to process the inclined hole in addition and cooperates, installation convenient operation, and application scope is wide, does benefit to popularization and application.
