Hexagon Bolt refers to the fastener composed of head and screw. According to the material, the bolt can be divided into iron bolt and stainless steel bolt, namely hexagon head bolt (partial thread) - C grade and hexagon head bolt (full thread) - C grade.
1. According to the stress mode of the connection, there are common and reamed holes. The bolts used for reaming holes should match the size of the holes and be used when subjected to transverse force
2. According to the head shape, there are hexagon head, round head, square head, countersunk head and so on. Generally, countersunk head is used in the place where the surface is smooth and no protrusion is required after connection, because countersunk head can be screwed into parts. Round head can also be screwed into parts. The tightening force of square head can be larger, but the size is large. Hexagon head is the most commonly used.
In addition, in order to meet the needs of locking after installation, there are holes in the head and in the rod, which can prevent the bolts from loosening when they are subject to vibration.
Some bolts have no thread of smooth rod to do thin, called thin waist bolt. This kind of bolt is conducive to variable force connection.
There are special high strength bolts on the steel structure. The head will be bigger. The size will also change.
In addition, there are special uses: T-shaped slot bolts, most of which are used in machine tool fixtures, with special shape, and both sides of the head need to be cut off. Anchor bolts are used to connect the machine and the ground, and there are many shapes, such as U-shaped bolts, and so on.
There are also special studs for welding, one with thread and the other without thread, which can be welded on the parts, and the other side can directly screw the nut.
