Yellow Plating Screw Hex Head Machine Thread Zinc Galvanized

Yellow plating screw is the screw with yellow zinc plating or yellow painting finish. Hex screw has hexagonal head and machine threads for use with a nut or in a tapped hole. Also known as hex bolt or machine bolt. Hex cap screw feature a washer face under the head and a chamfered point, whereas a hex bolt does not have a washer face or chamfered threads. They are made of low-carbon steel and are very common in construction or repair projects. Hex bolt is a very common choice when it comes to construction and repair. Hexagon screw head bolts come in a large variety of sizes and diameters. The best way to choose the right hex bolt is to find the bolt material that best suits your needs.

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. 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.
