What Are Hex Bolts Types

Hexagonal bolts are often used, so what are the classifications of hexagonal bolts? As a professional fastener manufacturer, Xinchi is happy to introduce you to the classification of hexagonal bolts.

Hexagon bolt is a fastener composed of a finger part and a screw. The bolts are divided into iron bolts and stainless steel bolts according to the material: hexagon head bolts (partially threaded)-C and hexagon head bolts (fully threaded)-C.

If it is classified according to the force mode of connection, hexagonal bolts have ordinary and hinged holes. The bolts used for reaming holes should match the size of the holes and be used when subjected to transverse forces.

If classified by head shape, hexagonal bolts have hexagonal heads, round heads, square heads, countersunk heads, and so on. Generally, the countersunk head is used in places where the surface is smooth without protrusions after connection, because the countersunk head can be screwed into the part. The round head can also be screwed into the parts, and the tightening force of the square head can be larger, but the size is large, and the hexagonal head is the most commonly used.

In addition, to meet the needs of locking after installation, there are holes in the head and holes in the rod part, which can make the bolt not loose when it is subjected to vibration.

Some bolts do not screw the rod to be thin, called thin waist bolts. This kind of bolt is good for connection under variable force.

The steel structure has special high-strength bolts. The head will be larger and the size will change.

In addition, there are special uses: T-slot bolts, the most used on the machine tool fixture, the shape is special, and the two sides of the head should be cut off. Anchor bolts are used for the connection between the machine and the ground, and there are many shapes, U-shaped bolts, such as the above-mentioned and so on.

There are special studs for welding, one end has a thread and one end does not, which can be welded on the part, and the other side directly screws the nut.
