Products Description:
The six angle bolt A common and articulated hole used in a
connected force. The bolt of a hinged hole should be fitted with
the size of the hole to be used when it is subjected to lateral
force.
There is a special high strength bolt on the steel structure. The
head will be bigger and the size changes
In addition, there are special uses: T grooved bolts, the most
commonly used machine tool clamps, the shape is special, and the
sides of the head should be cut off. The anchor bolts are used to
connect the machine to the ground, and there are many kinds of U
bolts.
Tin is a silver white metal, non-toxic, with good weldability and
ductility. It is widely used in electronics, food, automobile and
other industries. The tin plating process of six angle bolts is
classified into two categories: acid plating bath and alkaline tin
plating process by the pH value of the plating bath.
Advantage:
The advantage of acid tin plating is that the plating speed is
faster. And the coating is bright and meticulous, deep plating
ability. The plating solution has a strong tolerance to impurities,
and the operation at room temperature is more energy saving.
However, the plating method also has shortcomings, that is, the
dispersing ability of the bath is poor, the porosity of the coating
is higher, the brazing is not as good as the alkaline tin plating,
and the two valence tin is hydrolyzed. Therefore, the six angle
head bolt acid tin plating is divided into sulphate tin plating,
fluorborate tin plating and oxide tin plating because of different
conductive medium. At present, some special industrial six - corner
head bolts are used in this tin plating process.
