Din 933 Grade 8.8 Half Threaded Hex Bolts ,Steel Hex Bolt M3 - M42
Size
Products Description:
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 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
There is a special high strength bolt on the steel structure. The
head will be bigger and the size changes.
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.
