Grade 8.8 Half Threaded Steel Hex Bolt For Construction Industry
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.
According to the shape of the head six head, round, square head, countersunk head, and so on in connection to the smooth surface without protruding place head heavy, because the countersunk head can be screwed onto the parts. Also can be screwed into the round parts. With the tightening force can be bigger, but the large size six. The head is the most commonly used angle
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
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.
