The utility model has the advantages that the Self Drilling Screws screw rod of the utility model using multistage different-diameter screw rod part be connected with each other and
At silk can drill to innermost end connector, improve the tautness between connector；And antirust ability is strong, it is corrosion-resistant
Service life is up to complete effect；Its is acidproof；It is alkaline-resisting；For coastal area and the weatherability of high pollution weather；It is suitble to various corrosion-resistant
It is required that product and building.
Detailed description of the invention
Fig. 1 is the screw structural main view of the utility model；
Fig. 2 is the side view of Fig. 1；
Fig. 3 is multi stage screw structural schematic diagram.
Specific embodiment
The technical solution of the utility model is described in further detail combined with specific embodiments below.
As Fig. 1 to it is shown in Fig. 3 it is a kind of improve degree of being completely embedded coiled hair cross Self Drilling Screws, including coiled hair 1, screw rod 2,
Drilling tail 3, the one end of the screw rod 2 are fixedly connected with the coiled hair 1, the other end of the screw rod 2 and the fixed company of drilling tail 3
It connects, the screw rod 2 is connected and fixed by least one section of screw rod part, and screw thread is equipped on each screw rod part, and the screw thread is adopted
