Hexagon sockeT bolt type

According to the force mode of the connection, there are ordinary holes and reamed holes. For reamed holes, bolts should match the size of the hole and be used when subjected to lateral forces.

According to the shape of the head, there are hexagonal head, round head, square head, countersunk head and so on. Generally, the countersunk head is used where the surface is smooth and does not protrude after the connection, because the countersunk head can be screwed into the part. The round head can also be screwed into parts. The tightening force of the square head can be larger, but the size is large. Hexagonal heads are the most commonly used.

In addition, in order to meet the need of locking after installation, the head has a hole and the rod has a hole to prevent the bolt from loosening when it vibrates.

Some bolts have to be thin without threaded polished rods, which are called thin waist bolts. This bolt facilitates the connection under variable force.

There is a special high-strength bolt on the steel structure. The head will become larger and the size will also change.

In addition, it has a special purpose: T-slot bolts, which are the most commonly used in machine tool fixtures, have special shapes, and both sides of the head must be cut off. Anchor bolts are used to connect and fix machines and the ground, and have many shapes, such as u-shaped bolts, as described above.

There are also special welding studs, one with thread, one without, which can be welded to the part, and the other is directly tightened with a nut.
