Double Head Stud Black Headless Bolt Two Headed Bolts For Sports Equipment

Double head stud has the same length threads on each end usually to house a nut. Both ends have chamfered points. A stud is upright support in the wall of a building to which sheathing, drywall, etc., are attached. The stud is no head, only the two ends are threaded with a class of fasteners. When connecting it, one end must be screwed into the part with the internally threaded hole, the other end through the part with the through-hole, and then screwed on the nut, even if the two parts fastened together into a whole. This type of connection is called a stud connection and is also a detachable connection. Mainly used for one of the connected parts of the larger thickness, compact structure, or due to frequent demolition, should not be bolted to the occasion. 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 double head stud 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.
