Description:

The screw bolt: the head (with external thread of the cylinder) of two parts of fasteners, to cooperate with nut, used for fastening the two parts with hole. This kind of connection form according to bolt connection. Such as screw the nut on the bolt, and can make the two parts separately, so the bolt connection is a detachable connection.

According to the connection way of the stress points: ordinary articulation hole and have to use. According to the shape of the head points: hexagon head, round head, square head, countersunk head and so on. The hex head is the most commonly used. General countersunk head where required connection.

Applications:

Bolts, machine parts, with nuts cylindrical threaded fasteners

The application range of bolt are: electronic products, mechanical products, digital products, power equipment, mechanical and electrical machinery products. Vessels, vehicles, water conservancy projects, and even chemical experiment is also useful to bolt.

Specifications:

In accordance with the relevant standards, bolt performance are rated 3.6, 4.6, 3.6, 4.6, 6.8, 8.8, 9.8, 10.9, 12.9, and so on more than 10 levels, including a magnitude of 8.8 and above the bolt is made of low carbon alloy steel and medium carbon steel and the heat treatment (quenching and tempering), known as high strength bolts, the rest of the known as ordinary bolts. Bolt performance rating label consists of two parts Numbers respectively represent the nominal tensile strength value of bolt material and QuJiang ratio. For example: performance level 4.6 bolt, its meaning is: 1, the bolt material nominal tensile strength of 400 mpa grade; 2, bolt material QuJiang ratio is 0.6; 3, bolt material nominal yield strength of 400 * 0.6 = 400 mpa level performance grade 10.9 high strength bolt, its material after heat treatment, can be achieved: 1, the bolt material nominal tensile strength of 1000 mpa grade; 2, bolt material QuJiang ratio is 0.9; 3, bolt material nominal yield strength of 1000 * 0.9 = 900 mpa grade bolts performance level is the meaning of international standards, the same level of performance.
