Hanger Bolts Steel Yellow Zinc Plating Rohs Manufacturer

Hanger bolts have threaded areas at both ends: a lag screw thread at one end and a machine screw thread on the other. They are designed for insertion into a pre-drilled hole and are ideal for overhead applications, such as suspending electrical wiring or sheet metal from wooden structures. 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 hanger bolts 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.
