    Products Description:

    Six angle bolt: a fastener consisting of two parts, the head and the screw (the cylinder with external thread). It needs to cooperate with the nut to fasten and connect two parts with through holes.

    This form of connection is called a bolt connection. If the nut is swirled down from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.

    bolts need to go through the surface treatment, the fastener surface treatment methods are many commonly used are electroplating, oxidation, phosphating, hot dip galvanizing, sandblasting, and so on. Plating generally white zinc, yellow zinc, blue zinc and so on. Galvanized zinc plating is much thicker than plating, gloss is not good looking plating. Plating screws in the automotive, rolling machine, household appliances, instrumentation, aerospace, communications and other occupations and fields in a wide range of applications. In general, the fastener surface treatment is done to protect the screws from friction damage, and given the screw surface beautiful, anti-corrosion, anti-loosening effect.

    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.

     

     

    application


    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.
