Two Ended Screw Double Threaded Fasteners Black Steel Socket Inserts

The two ended screw is also known as double ended inserts. They are the nut with both internal thread and external thread. It’s usually custom made according to client’s request or drawing. A threaded bushing, also known as a threaded insert, is a fastener element that is inserted into an object to add a threaded hole.screws for mill inserts. Ever Hardware provides the custom-made two ended screw 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 two ended screw 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, 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.
