Carbon steel: We distinguish low carbon steel, medium carbon steel and high carbon steel as well as alloy steel with carbon content in carbon steel. stainless steel: Performance rating: 45, 50, 60, 70, 80. copper: Common materials [...]
There are two types of screw surface inspections, one is the inspection before the screw is produced, and the other is the inspection after the screw plating. Inspection method after screw treatment: Appearance quality requirements: The inspection of the appearance of the screws is carried out in terms of appearance, plating and other aspects. Inspection [...]
Annealing: The wire is heated to a suitable temperature for a certain period of time, and then slowly cooled to adjust the crystal structure, reduce the hardness, and improve the normal temperature processability of the wire. Pickling: removes the oxide film on the surface of the wire and forms a phosphate film on the metal [...]
Eyebolts Technical Requirements Eyebolts shall be made of 20 or 25 steel (GB699). The eyebolts must be integrally forged. Forgings should be normalized and the scale removed. The grain size of the finished product should not be lower than Grade 5 (GB6394), and the forgings should not have over-burning or crack defects. In order to [...]
Eye bolts are widely used in ports, electric power, steel, shipbuilding, petrochemical, mining, railway, construction, metallurgical chemical, automobile manufacturing, plastic machinery, industrial control, highway, large-scale transportation, pipeline auxiliary, slope tunnel, well treatment Protection, marine assistance, offshore engineering, airport construction, bridges, aviation, aerospace, stadiums and other important industries as well as mechanical equipment for infrastructure projects. [...]
Eye bolt, as a standard fastener, is widely used in mechanical and electrical products. Its main function is lifting load. Eye bolts generally do not undergo surface treatment, but according to the use requirements, can be passivated by galvanizing, chromium plating and other surface treatment. Dehydrogenation should be carried out immediately after galvanizing. The lifting [...]
Eye bolts are widely used in port, shipbuilding, railway, construction, plastic machinery, industrial control, pipeline auxiliary, marine rescue, Airport construction, aerospace, venues and other important industries as well as mechanical equipment of infrastructure projects. Cautions for using eye bolts: Users must be trained before they can use the product. In order to use the product [...]
T-slot bolt T-slot bolts are used where bolts can only be joined from one side of the joined part. Insert the bolt from the T-slot and turn it 90 degrees to make the bolts unable to escape. It can also be used in applications where the structure requirements are compact. Anchor bolt For the pre-buried [...]
Hexagon head reaming bolt The hinged hole bolts accurately fix the mutual position of the linked parts and can withstand shear and extrusion in the transverse direction. Cross recessed hex head bolt Easy to install and tighten, mainly used for light work and instrumentation with less load Square head bolt The square head bolt has [...]
Hex Bolts Hex bolts are one of the most widely used types of bolts. Its Class A and Class B bolts are used for important applications where high assembly accuracy is required and subjected to large shocks, vibrations or alternating loads. Its C-class bolts are used in applications where the surface is rough and the [...]
The degree of tightening of ordinary bolts is not clearly defined, and the force applied during locking is generally as long as the connection is tight. However, since the tension is not applied when the lock is applied, the nut is prone to loosening. To prevent loosening, the inner nut can be pressed by the [...]
The riveting bolts were still widely used until the 1950s, but the construction process of the riveting bolts was not only dangerous but also difficult for professional technicians. It also produced noise resistance during construction, and the construction quality was difficult to control due to the strength and clamping efficiency of the riveting bolts. In [...]
Install expansion screw prepare tools: hand drill, hammer, cross screwdriver, pencil. After preparing the tool, select an alloy drill bit of the same diameter as the expansion screw of the expansion screw, install it on the drill and then punch the wall. The depth of the hole is preferably the same as the length of [...]
The bracket bolt has a dome or sink head, and the top of the handle has a short square section under the head of the bolt. The square part is clamped into the fixed part to prevent the bolt from turning when the nut is tightened. Bracket bolts are usually used to fix boards or [...]
The Plow Bolts are designed with a short square sinking head under the head of the bolt. The square part is used to prevent rotation when fastened through nuts. Plow Bolts are usually used in plow and other heavy equipment. The name of these bolts comes from connecting the cutting edge of the plow to [...]
As its name suggests, Carriage Bolts inserts the square neck of the head into the groove of the connector, reduces the height of the protruding surface and tightens the screw from the opposite side. It is mostly used in places where the force is not large, so the material is relatively soft. Carriage Bolts features [...]
Hexagonal bolt material At present, the hexagonal bolts in the market are mainly made of carbon steel, stainless steel and copper. Carbon steel. We distinguish low-carbon steel, medium-carbon steel, high-carbon steel and alloy steel by carbon content in carbon steel. Low carbon steel C%<0.25% is commonly referred to as A3 steel in China. Foreign countries [...]
Classification of Hex Bolts Hex Bolts are divided into outer hexagonal bolts and inner hexagonal bolts. According to the force mode of connection, there are ordinary and hinged holes.
