The bolt hexagon socket head is used to connect the fixed connection of mechanical equipment. The hot-dip galvanized stud bolts have external threads on both sides, and the extruder screw in the middle is thick or thin, sometimes called as Double-ended screw. Hot-dip galvanized studs are mainly used for mining equipment, highway bridges, vehicles, motorcycles, heating furnace steel frame structures, hanging towers, long-span steel frame structures and large and medium-sized engineering buildings.

The classification method and actual classification of hot-dip galvanized stud bolts and their main uses:

1. According to the bearing method of screw connection: divided into general and hinged holes. The general key bearing axial bearing force can also be installed with a lateral bearing force that is not too high. The anchor bolts used for the reaming holes should be matched with the specifications of the holes, and are used when they are subjected to lateral force;

2. According to the top of the head, there are hexagonal head, round head, square head, countersunk head, and stud bolts. Among them, the hexagonal head is the most common. Generally, the countersunk head is used in the area where the surface is smooth and not raised after the specified connection anchor bolt, because the countersunk head can be screwed into the part. The round mouth can also be screwed into the part. The tightening force of the square head can be larger, but the specifications are very large;

3. In addition, there are unique uses: TV-shaped groove anchor bolts, the number of which is placed on the chuck of the machine tool is the most, and the appearance is unique. Both sides of the top of the head should be cut off. Anchor screws, which are used to connect equipment and road surfaces to be fixed, have a variety of shapes. U-bolt;

4. China bolts factory wholesale hot-dip galvanized stud bolts and anchor screws also have special nuts for electric welding. One end has external threads and the other end does not, which can be welded to the parts, and the other end is immediately screwed with nuts.
