Characteristic
Carbon steel bolts can be divided into ordinary holes and reamed holes according to the stress mode of connection.
According to the shape of the head, it can be divided into hexagonal, circular, square, countersunk, etc.
Hexagon head is the most commonly used. Generally, countersunk heads are used for special connections.
Application
Carbon steel bolts are used in industrial production, industrial buildings and railway tunnels;
Road and road bridges, pipelines and road bridges, towers and arched structures;
It can also be used for heating furnace structure, heating furnace steel frame structure and large-span workshop;
High rise residential and industrial buildings, various towers, light steel structures, lifting equipment, etc.
