Abstract
The utility model discloses a triangular-screw-head inflexible glueternal-pentangular full-thread flange screw, which includes a triangular screw head (1) and a screw rod (2), wherein an internal pentangular counter bore (3) is formed on the triangular screw head (1), a flange plate (4) is arranged between the triangular screw head (1) and the screw rod (2), the screw rod (2) adopts a full-thread section, and a through hole (5) is axially formed on the screw rod (2) and communicated with counter bore (3). The triangular-screw-head internal-pentangular full-thread flange screw does not slip during the screwing process and saves material.
Description
Technical field
The utility model relates to a kind of fastening piece, specifically is five jiaos of Full Thread FT flange screws in a kind of triangle spiral shell head.
Background technique
The triangle spiral shell head screw of prior art comprises that cross section is that leg-of-mutton spiral shell head is triangle spiral shell head and screw rod, and it is hexagonal counterbore that described spiral shell head is provided with cross section, promptly interior hexagonal counterbore, and described screw rod is a solid screw.
There is following defective in the triangle spiral shell head screw of prior art: at first, be interior hexagonal counterbore owing to what establish on the spiral shell head, in actual use, when screwing this screw with hexagon wrench, often skid easily; Secondly, because screw rod is solid, relatively take material, cost is than higher.
The model utility content
The technical problems to be solved in the utility model is, provides a kind of non-slip and save five jiaos of Full Thread FT flange screws in the triangle spiral shell head of material in screwing the process of this screw.
Technical solution of the present utility model is, a kind of interior five jiaos of Full Thread FT flange screws of triangle spiral shell head with following structure are provided, it comprises triangle spiral shell head and screw rod, described triangle spiral shell head is provided with interior five jiaos of counterbores, be provided with flange plate between described triangle spiral shell head and the screw rod, described screw rod is thread section entirely, and described screw rod is through with through hole along axis, and described through hole is communicated with counterbore.
After adopting above structure, five jiaos of Full Thread FT flange screws compared with prior art have the following advantages in the utility model triangle spiral shell head:
Because the counterbore on this spiral shell head is interior five jiaos, according to general knowledge as can be known, many more easy more the skidding of polygonal seamed edge are that circle is the easiest as the infinite many limit polygonals of seamed edge in the polygonal skids, so the screw of interior five jiaos of counterbores screws, more is difficult for skidding than interior hexagonal counterbore screw is more convenient; And because screw rod is through with through hole along axis, obviously, cored screw is than solid screw material saving more, and cost is lower.
