Countersunk or flat head
Conical, with flat outer face and tapering inner face allowing it to sink into the material. The angle of the screw is measured as the full angle of the cone.

 

Raw Material: Carbon Steel

Carbon steel is a steel with carbon content up to 2.1% by weight.

 

As the carbon percentage content rises, steel has the ability to become harder and stronger through heat treating; however, it becomes less ductile. Regardless of the heat treatment, a higher carbon content reduces weldability. In carbon steels, the higher carbon content lowers the melting point.

 

Galvanization

Galvanization (or galvanizing as it is most commonly called in that industry) is the process of applying a protective zinc coating to steel or iron, to prevent rusting.

 

Galvanising protects the underlying iron or steel in the following main ways:

  • The zinc coating, when intact, prevents corrosive substances from reaching the underlying steel or iron.
  • The zinc serves as a sacrificial anode so that even if the coating is scratched, the exposed steel will still be protected by the remaining zinc.
  • The zinc protects iron by corroding first. For better results, application of chromates over zinc is also seen as an industrial trend.
