In order to overcome the defects of the prior art, a thin hexagonal cross washer drill tail screw is provided, and the problems that the existing round-torque cross groove self-tapping screw is poor in use flexibility, a cross bit is easy to wear and slip in the use process, the edge of a cross groove is slightly worn and deformed, a plating layer around the cross groove is easy to rust due to falling off, the thickness of the screw head is more within 3.8-4.3mm specified by the national standard, and the subsequent clad plate is not facilitated are solved.
(II) technical scheme
The utility model discloses a following technical scheme realizes: the utility model provides a tail screw is bored to slim hexagonal cross china department, including screwhead and cross recess, the screwhead include the hexagonal head of upper end and the shaping in the flange china department of hexagonal head bottom, hexagonal head upper end middle part shaping has the cross recess, the peripheral shaping in flange china department bottom is fluted, screwhead thickness is within 3 mm.
Through adopting above-mentioned technical scheme, through the screwhead sets up the hexagon head with the cross recess for this screw can use with the cooperation of outside sleeve, can use with the cooperation of outside screwdriver again, has effectively avoided wearing and tearing of screwhead and the coming off of cladding material, has improved the flexibility that the screw used, and screwhead thickness is less than 3mm simultaneously, is favorable to subsequent shroud plate.
Furthermore, a screw rod is formed in the middle of the bottom end of the screw head, and external threads are formed on the peripheral side wall of the screw rod.
By adopting the technical scheme, the workpieces can be reliably connected through the external threads.
Furthermore, a drill tail is formed at the bottom end of the screw rod, and a chip removal groove is formed in the peripheral side wall of the drill tail.
Through adopting above-mentioned technical scheme, through the chip groove can in time discharge the sweeps of screw in drilling process for the screw can drill smoothly.
Furthermore, a drill bit is formed in the middle of the bottom end of the drill tail, and a drill edge is arranged on the peripheral side wall of the drill tail.
Through adopting above-mentioned technical scheme, through the drill bit can realize the quick drilling of screw.
(III) advantageous effects
Compared with the prior art, the utility model, following beneficial effect has:
the utility model discloses a set up hexagon head and cross recess at the screwhead, make this screw can use with the cooperation of outside sleeve, can use with the cooperation of outside screwdriver again, effectively avoided wearing and tearing of screwhead portion and cladding material to drop, improved the flexibility that the screw used, screwhead thickness is less than 3mm simultaneously, is favorable to subsequent shroud plate.
