Abstract
The utility model relates to a screw nail comprising a screw nail body, the thread area thereof is uniformly distributed with helical teeth, also referred to as coarse teeth. The parallel space between two coarse teeth gradually widens, which improves the nail-holding power for plastic or wooden board materials; the surface at the nail end part of the screw nail body is provided with a hexagonal screwing groove capable of withstanding heavier torsion and preventing a screwdriver from slipping; the nail head of the screw nail body is provided with a cutting groove having a cutting function and at the same time facilitating the discharge of plastic wooden chips when the screw nail is screw therein. The screw nail of the utility model adopts coarse teeth in its constitution, contains increased space between two coarse teeth, introduces a hexagonal screwing groove and opens a cutting groove at the nail head, which substantially increases the second and third nail-holding power for the plastic and wooden board materials and increases working efficiency as well; at the same time, working intensity is greatly reduced too; the instrument has a longer service lifetime while achieving a better outlook.
Description
Technical field
The utility model relates to a kind of screw.
Background technique
When we are being fixed on an object on the solid plastic wood sheet, generally always select to adopt common tapping screw.This needs following two procedures: draw the hole with parallel shank twist drill in advance, and then screw in tapping screw.If, need just to have following 2 problems with common self-drilling self-tapping screw: one, the pitch of common self-drilling self-tapping screw is too intensive, 2 times, it is zero that 3 nail-holding abilitys tend to be essentially, its two, the nail tail of common self-drilling self-tapping screw is bigger, is not easy to hidden nail tail.
The model utility content
The purpose of this utility model provides a kind of screw, to have improved work efficiency, has reduced labor intensity, has improved the working life of instrument.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of screw comprises screw body, and the threaded area of described screw body is evenly distributed with the spiral shell tooth, and the spiral shell tooth is a bastard, and the parallel distance broadening of spiral shell tooth is to improve the nail-holding ability of plastic wood sheet; The nail tail surface of described screw body is provided with hexagon and screws in groove, can bear more torsion, prevents that screw-driver from skidding; The ailhead of screw body is provided with and mills groove, mills groove and has the cutting function, helps the fashionable discharge of moulding wood chip of screw threads simultaneously.
The beneficial effects of the utility model are: improved 2 times, 3 times nail-holding abilitys of plastic wood sheet, improved work efficiency; Reduce labor intensity, improved the working life of instrument.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the structural representation of a kind of screw described in the utility model;
Fig. 2 is the planimetric map of nail tail.
Among the figure:
1, screw body; 2, ailhead; 3, nail tail; 4, spiral shell tooth; 5, screw in groove; 6, mill groove.
Embodiment
Shown in Fig. 1-2, the described a kind of screw of the utility model embodiment, screw is handled through over carburizing and associated hot, makes it have high hardness, wear resistance and fatigue resistance.The threaded area of described screw body 1 is evenly distributed with spiral shell tooth 4, and the spiral shell tooth is a bastard, and the parallel distance broadening of spiral shell tooth 4 has improved the nail-holding ability of plastic wood sheet and accelerated working efficiency, and the bastard design also helps the high speed of moulding wood chip and discharges; Nail tail 3 surfaces of described screw body 1 are provided with hexagon and screw in groove 5, can bear more torsion, prevent that screw-driver from skidding; The ailhead 2 of screw body 1 is provided with and mills groove 6, mills groove 6 and has the cutting function, helps the fashionable discharge of moulding wood chip of screw threads simultaneously.
