Grooved Pins Headless Steel Iron Stainless Custom Galvanization

Grooved pins are the pin with grooves on the surface, it may be made by cold heading or lathe finish. Inserted into receiving holes, grooved pins hold together parts of an assembly with friction. They may also be used as location pins. These pins are common in the automotive and aerospace industries as well as in furniture making. Ever Hardware provides custom-made fasteners and customizable packaging.

Galvanization, or galvanisation, (or galvanizing as it is most commonly called in that industry), prevent the grooved pins from rust, 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.

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.
