Hot-DIP Galvanized Ground Anchor Screw

Descriptions:
The screw is in a shape of a cylinder with a spiral groove cut on the outer surface or a cone with a spiral groove cut on the conical surface.It has many types with different head shape,such as external hexagonal screw,large flat screw and socket hexagon screw and so on.

Material requirement:
As the screw is working in condition of high temperature,certain corrosion, strong wear and large torque,it must reach the following requirements:
1) high temperature resistance, no deformation at high temperature;
2) wear resistance, long service life;
3) corrosion resistance, corrosive materials;
4) high strength, can withstand large torque, high speed;
5) good cutting performance;
6) low residual stress and thermal deformation after heat treatment.

Application:
