Abstract
The utility model discloses a full-thread pentagonal bolt which comprises a bolt head (1) and a screw rod (2), wherein the bolt head (1) and the screw rod (2) are connected into a whole, the bolt head (1) is a protruding pentagon, the screw rod (2) has full thread, a through hole (3) runs through the centers of the bolt head (1) and the screw rod (2) along the axial direction, the bolt head (1) is provided with a pentagonal counter bore (4), and the pentagonal counter bore (4) is communicated with the through hole (3). The full-thread pentagonal bolt is hollow instead of solid, and during manufacturing and processing, material can be saved and cost can be reduced. In addition, the bolt head (1) not only has the specification of external pentagon in the prior art, but also has the specification of internal pentagon.
Description
Technical field
The utility model relates to a kind of bolt, particularly a kind of Full Thread FT five corner bolts.
Background technique
Screw bolt generally is made up of bolt head, screw rod, and screw portion is a Full Thread FT.Full Thread FT five corner bolts on the market all are solid, and promptly the screw rod of five jiaos of screw threads of Full Thread FT and bolt head all are solid, and the use material is more, manufacture cost is higher.And the outer five angle gauge lattice of the general employing of the bolt head of Full Thread FT five corner bolts of prior art promptly have only a kind of specification.
The model utility content
The technical problems to be solved in the utility model is, overcomes above deficiency, provides a kind of and has two kinds of specification bolt heads, can save material, reduced Full Thread FT five corner bolts of manufacture cost.
In order to address the above problem, the technical solution of the utility model is: a kind of Full Thread FT five corner bolts, comprise bolt head and screw rod, described bolt head and screw rod are connected in one, described bolt head is the pentagon of evagination, and described screw portion is a Full Thread FT, and the center of described bolt head and screw rod is prolonged and axially is penetrated with through hole, described bolt head is provided with five jiaos of counterbores, and described five jiaos of counterbores and described through hole connect.
After adopting above technological scheme, the utility model Full Thread FT five corner bolts compared with prior art have the following advantages: the center of bolt head of the present utility model and screw rod is prolonged and axially is penetrated with through hole, that is to say that the utility model Full Thread FT five corner bolts are hollow, rather than solid.This kind design when making Full Thread FT five corner bolts, has been saved the use material, has been reduced manufacture cost.The bolt head of the utility model bolt head is provided with five jiaos of counterbores, five angle gauge lattice just, the bolt head that makes Full Thread FT five corner bolts except the pentagon specification of evagination with prior art, just outer five angle gauge lattice, also have of the present utility model in five angle gauge lattice.
