Description
Technical field
The present invention relates to nonstandard screw field, more particularly to a kind of cross recessed pan head tapping screw.
Background technology
Tapping screw, the entitled Self-tapping Screw of English be in the prebored hole of metal or nonmetallic materials from
Row, which attacks the one kind for drilling out negative thread joined together, threaded fasteners.Tapping screw is used for thin metallic plate（Steel plate, saw plate etc.）It
Between connection.During connection, thread Pilot hole is first made to connected piece, then tapping screw is screwed into the thread Pilot hole of connected piece
In.
Tapping screw head shape has a round end, tack, countersunk raised head and countersunk head etc., and material is generally with based on 1022 medium carbon steel.
Because intensity and hardness are inadequate, in assembling process spontaneous disruption or sliding dental phenomenon can occur for existing tapping screw.
The content of the invention
The present invention solves the technical problem of a kind of cross recessed pan head tapping screw is provided, can solve existing self tapping spiral shell
Drawbacks described above existing for nail.
In order to solve the above technical problems, one aspect of the present invention is：A kind of cross recess coiled hair self tapping is provided
Screw, including：The body of screw, the coiled hair positioned at described body of screw one end, cross groove is offered in the middle part of the coiled hair, it is described
It is integrally machined the pin thread being distributed in the shape of a spiral on the body of screw, the cross section of the pin thread is into triangle, the body of screw
It is to use made of Aldecor, and plating has corrosion-resistant zinc in the outer surface of the Aldecor body of screw
Alloy-layer.
In a preferred embodiment of the present invention, the chemical element and its quality percentage that the Aldecor includes
Than for：Carbon 0.1%-0.2%, manganese 0.5%-0.8%, titanium 0.15%-0.2%, aluminium 0.8%-1.2%, nickel 0.6%-0.9%, remaining be iron and
Inevitable impurity.
In a preferred embodiment of the present invention, inevitably impurity content≤0.01%.
In a preferred embodiment of the present invention, the junction of the coiled hair and the body of screw is provided with packing ring.
The beneficial effects of the invention are as follows：The body of screw of the present invention is used made of Aldecor, and in the height
The outer surface plating of the strength low alloy steel body of screw has corrosion-resistant zinc alloy layer, makes it have good intensity and corrosion resistance
Can, be not in fracture or sliding dental phenomenon in assembling process.
