Hex Flange Drilling Screw Manufacturer Zinc Plating

Hex flange drilling screw is a self-drilling screw with a hexagon flange head. Hex flange drilling screw enables drilling without first creating a pilot hole. These screws are usually used to join materials like sheet metal. elf drilling screws, also known as Tek screws, are fasteners with a special pointed end style that allows them to penetrate thin materials without a starting or pilot hole. Also known as self-tapping screws or self-drilling bolts, they cut or form threads to engage with the mating material. Ever Hardware provides custom-made fasteners and customizable packaging.

Galvanization, or galvanisation, (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. The most common method is hot-dip galvanizing, in which parts are submerged in a bath of molten zinc. Galvanizing protects in three ways:
It forms a coating of zinc which, 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 its base metal by corroding before iron. For better results, the application of chromates over zinc is also seen as an industrial trend.
Hot-dip galvanizing is the process of immersing iron or steel in a bath of molten zinc to produce a corrosion-resistant, multi-layered coating of zinc-iron alloy and zinc metal. While the steel is immersed in the zinc, a metallurgical reaction occurs between the iron in the steel and the molten zinc. This reaction is a diffusion process, so the coating forms perpendicular to all surfaces creating a uniform thickness throughout the part.
