Acorn Nut Dome Nut Cap Nut Black Plating Galvanized

Acorn nut is also known as dome nut or cap nut. Acorn nut is a type of fastener that gets its name from its shape. Acorn nut is its common name and it is also called a crown hex nut, blind nut, cap nut, or domed cap nut. It is a nut that has a domed top to cover the threads. This is to prevent contact with the external thread to protect the threads or protect other things the threads would rub against. In addition, the dome gives a more finished appearance. It is usually made of brass, steel, stainless steel (low carbon content), or nylon. It can also be chrome-plated and given a mirror finish. Ever Hardware provides custom-made fasteners and customizable packaging.
There are two types of acorn nuts. One is low, or the standard acorn nut. The other is the high acorn nut. The high acorn nut is wider and higher and will protect extra long studs. There are also self-locking acorn nuts that have distorted threads in the hex area to create a tight friction fit to prevent the nut from vibrating loose.

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 acorn nut 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.
