DIN 931 Hex Bolt With Nut Carbon Steel Grade 8.8 Dacromet Surface Hex Head Bolt
Dacromet (Dacrotized), also known as zinc chrome film coating with high corrosion resistance, in China is in the process of cleaner production, and one high-tech germination stage, known as the epoch-making international surface treatment industry new technology sense. This process can replace even electro-galvanized steel, cadmium, zinc based alloys, hot dip galvanized, thermal spray zinc, galvanized machinery.
Hexagonal bolts: a two-part type fasteners, to be with the nut and the screw head with the (externally threaded cylinder) for fastening two parts with hole.
This connection type called bolt connection. As to unscrew the nuts from the bolts, so that the two parts can be separated, so bolting belongs detachable connection.
Dacromet is a new surface treatment technology, compared with conventional plating process, Dacromet is a "green electroplating." Its advantages are the following:
1) superior corrosion resistance: Dacromet coating thickness of only 4-8μm, but the rust is 7-10 times more than conventional electro-galvanized, hot dip galvanized or paint coating method. Standard parts are Dacromet processing, pipe fittings by salt spray test 1200h more red rust did not appear.
2) no hydrogen embrittlement: Dacromet treatment process determines the dacromet no hydrogen embrittlement, it is very suitable for coating Dacromet force member.
3) High heat resistance: Dacromet high temperature corrosion can heat up to temperatures above 300 ℃. The traditional zinc plating process, the temperature reached 100 ℃ has been scrapped from the skin.
Good 4) binding and apply a performance: Dacromet coating and the metal substrate with good adhesion, and strong adhesion with other additional coatings, the treated parts easy to spray colored, in combination with organic coating force even more than the phosphate coating.
5) Good permeability: electrostatic shielding effect, the workpiece hole, slit, fittings and other parts of the inner wall of the zinc plating is difficult, so the above parts of the workpiece can not be protected by plating method. Dacromet you can enter these parts of the workpiece is formed Dacromet.
