Grade 8.8 Half Threaded Hex Bolts ,Steel Hex Bolt Din 933 For Architecture

Products Description:

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.

The six angle bolt is a fastener consisting of fingers and screws. The bolts are divided into iron bolts and stainless steel bolts according to the material, namely the six angle head bolts (partial threads) -C and six angle bolts (full thread) -C level.

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

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.
