Fine Thread Hex Head Tap Bolt ,  Structural Hex Head Fasteners Silver White Metal

Fully Threaded Hex Bolts White Heavy Hex Structural Bolts

Products Description:

Six angle bolt, six angle head bolt (part screw) -C and six angle head bolt (full thread) -C. Also known as the six hexagon head bolts (coarse hair) six hexagon head bolts, iron screws.

In order to meet the needs of locking after installation, there are holes in the head, and the rod has holes. These holes can make the bolts free from loosening when they are vibrated.

Some bolts are not thread rod to do fine, is conducive to the slender waist bolt. The bolt connection under variable force

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.
