1. Bolt is A type of fastener consisting of head and screw (cylinder with external thread), which needs to be matched with nut to fasten and connect two parts with through-hole
2. There are hexagonal head, round head, square head, countersunk head and so on. Hexagonal head is the most commonly used. General countersunk head is used for required connection
3. The back surface is smooth without protrusion, because the countersunk head can be screwed into the part. The round head can also be screwed into the part. The tightening force of the square head can be larger, but the size is large.
4. In addition, in order to meet the need of locking after installation, if there are holes in the head and the rod, these holes can prevent the bolt from loosening when it is vibrated.
5. The polished rod of some bolts without threads should be made thin, which is called thin waist bolt. This kind of bolt is beneficial to the connection under variable force.
6. There are special high-strength bolts on the steel structure, the head will be larger, and the size will also change.
In addition, there are special uses: T-groove bolts are used, and most of them are used on machine tool clamps. The shape is special, and both sides of the head should be cut off. Anchor bolts, which are used to connect and fix the machine and the ground, have many shapes. U-bolt, as described above. wait.
7. There are also special studs for welding, with threads at one end and no threads at the other end, which can be welded on the parts, and the nuts can be directly screwed on the other side
