What are the main classifications of U-bolts? Let's take a look at the main classification of U-bolts.

Divided by the connected force

Ordinary and hinged. Ordinary main bearing axial force can also carry less demanding lateral force. Bolts for hinged holes must match the size of the hole and are used when subjected to lateral forces.

Divided by head shape

Hex head, round head, square head, countersunk head and so on. Hex heads are the most commonly used. Generally countersunk head is used to connect

The back surface is smooth and no protrusions, 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. In addition, in order to meet the need for locking after installation, there are holes in the head and holes in the rod. These holes can prevent the bolt from loosening when subjected to vibration. Some bolts without threads need to be thin, called thin waist bolts. Such bolts are conducive to joints subject to variable forces. There are special high-strength bolts on the steel structure, the head will be larger, and the size will change. In addition, there are special uses: T-slot bolts, the most commonly used on machine tool fixtures, special shapes, cut off both sides of the head. Anchor bolts are used for fixing the machine to the ground and come in many shapes. U-bolts, as before. and many more. There are also special studs for welding. One end is threaded and the other is not. It can be welded to the part and the other side is directly screwed.
