Abstract
The utility model discloses an outer hexagonal screw comprising a screw rod part and an outer hexagonal head part. The outer hexagonal screw is characterized in that the end face of the outer hexagonal head part is provided with an inner hexagonal groove, and the end face of the screw rod part is also provided with an inner hexagonal groove. The outer hexagonal screw can be screwed tightly by an outer hexagonal wrench and an inner hexagonal wrench, is strong in practicality, can effectively solve the problem of self rotation of the outer hexagonal screw during installation and detachment processes, and enables the installation and detachment processes to be simple and labor-saving.
Description
[technical field]
The utility model relates to a kind of fastening piece, is specifically related to a kind of outer-hexagonal bolts.
[background technique]
Outer-hexagonal bolts is a kind of common connection fastening piece, must be indispensable in industrial production and Assembling Production.Outer-hexagonal bolts can only be wrenched and unclamp with outer hexagonal spanner, tool using is single, and outer-hexagonal bolts and nut screw or when unclamping, if having screw thread damages, the situations such as screw thread gets rusty, when rotating screw or nut, screw and nut rotates together possibly and produces rotation, if can not carry out respectively independently pulling this moment to screw and nut, make between the screw and nut and produce relative rotation, wanting to be wrenched or unclamping connecting between screw and the nut is exactly a very difficult thing, the installation and removal process is become to waste time and energy, even can't carry out.
[summary of the invention]
For the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of available outer hexagonal spanner and inner hexagon spanner to be wrenched, practical, and can effectively solve rotation problem in installation, the unloading process, make installation, the unloading process simple labour-saving outer-hexagonal bolts that becomes.
The utility model takes following technological scheme to finish:
A kind of outer-hexagonal bolts comprises screw portion and outer-hexagonal head part, and it is characterized in that: the end face of described outer-hexagonal head part is provided with interior hexagonal groove, and the end face of described screw portion also is provided with interior hexagonal groove.
The outer-hexagonal bolts of technique scheme, at first the outer-hexagonal head is provided with interior hexagonal groove simultaneously, thus can use outer hexagonal spanner and inner hexagon spanner to be wrenched, practical; Secondly, if in installation, unloading process, the rotation problem occurs, and screw outer-hexagonal head can not be pulled operation with outer hexagonal spanner, that can pull operation by the interior hexagonal groove that the screw portion end face is provided with to screw with inner hexagon spanner, make between the screw and nut and produce relative rotation, so, the rotation problem between screw and nut just can obtain very simple and effective processing, makes installation, unloading process become simply laborsaving.
[description of drawings]
The utility model has following accompanying drawing:
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the directional diagram of overlooking of Fig. 1.
[embodiment]
As shown in the figure, outer-hexagonal bolts of the present utility model comprises screw portion 2 and outer-hexagonal head part 1, and the end face of described outer-hexagonal head part 1 is provided with interior hexagonal groove 3, the end face of described screw portion 2 also is provided with interior hexagonal groove 4, and namely two of outer-hexagonal bolts all is provided with interior hexagonal groove.
Outer-hexagonal bolts of the present utility model can use outer hexagonal spanner and inner hexagon spanner to be wrenched, and is practical, and can effectively solve the rotation problem in installation, the unloading process, makes installation, unloading process become simply laborsaving.
