Abstract

The utility model discloses a full thread hexagon bolt. The full thread hexagon bolt comprises a first external hexagonal head portion (1) and a screw (3). The full thread hexagon bolt is characterized in that a second external hexagonal head portion (4) is arranged at the outer end of the first external hexagonal head portion (1), the outer diameter of the second external hexagonal head portion (4) is smaller than that of the first external hexagonal head portion, and a radial through hole (4.1) is formed in the head portion of the second external hexagonal head portion (4). The full thread hexagon bolt applies to wrenches well.

Description

A kind of Full Thread FT hex head bolt
Technical field
The utility model relates to fastening piece, specifically is a kind of Full Thread FT hex head bolt.
Background technique
Present Full Thread FT hex head bolt comprises bolt head and screw rod, the bolt of this routine is actual to exist following shortcoming when using: only be suitable for a kind of specification spanner because the outer-hexagonal size of bolt head is general, when turning, can only adopt a kind of spanner of specification, poor for applicability.
The model utility content
The technical problems to be solved in the utility model is to provide a kind of spanner applicability good Full Thread FT hex head bolt.
The technical solution of the utility model is, a kind of Full Thread FT hex head bolt with following structure is provided, and comprises first outer-hexagonal head and the screw rod; The outer end of the described first outer-hexagonal head also is provided with the second outer-hexagonal head, and the second outer-hexagonal head outer diameter is less than the first outer-hexagonal head, and the head of the described second outer-hexagonal head is provided with radial direction through hole.
The described second outer-hexagonal head pastes mutually with the first outer-hexagonal head.
The center of the center of the described first outer-hexagonal head and the second outer-hexagonal head is on same straight line.
After adopting said structure, the utility model compared with prior art, have the following advantages: because the outer end of the described first outer-hexagonal head also is provided with the second outer-hexagonal head, and the second outer-hexagonal head outer diameter is less than the first outer-hexagonal head, when pulling, be suitable for the spanner of two kinds of specifications, applicability is good.Because the head of the described second outer-hexagonal head is provided with radial direction through hole, and the strip instrument can pass radial direction through hole wrenching bolt again, applicability is good again.
Description of drawings
Accompanying drawing 1 is the structural representation of a kind of Full Thread FT hex head bolt of the present utility model.
Accompanying drawing 2 is schematic side view of the present utility model.
Shown in the figure, 1, the first outer-hexagonal head, 3, screw rod, 4, the second outer-hexagonal head, 4.1, radial direction through hole.
Embodiment
