One Way Screw Flat Head Special Threaded Tip End Galvanization

One way screw is the screw with special inverted threaded, that thread allows screw-lock into a hole but does not allow is out of the hole. Flathead does not allow even a tool to try to move the screw out. Tip end is for tapping into a hole. Ever Hardware provides custom-made fasteners and customizable packaging.

Galvanization prevents the one-way screw from rust. Zinc coatings prevent oxidation of the protected metal by forming a barrier and by acting as a sacrificial anode if this barrier is damaged. Zinc oxide is a fine white dust that (in contrast to iron oxide) does not cause a breakdown of the substrate’s surface integrity as it is formed. Indeed, the zinc oxide, if undisturbed, can act as a barrier to further oxidation, in a way similar to the protection afforded to aluminum and stainless steels by their oxide layers. The majority of hardware parts are zinc-plated, rather than cadmium-plated.
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.
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.
