Hex bolt manufacturers are manufacturers that produce hexagonal bolts. Hexagonal bolts refer to fasteners composed of heads and screws. Bolts are divided into iron bolts and stainless steel bolts according to their materials, namely, hexagonal head bolts (partially threaded)-C and hexagonal Bolt (full thread)-Grade C.
- According to the force mode of the connection, there are ordinary and reamed holes. The bolts used for reaming holes should be matched with the size of the hole and used when subjected to lateral forces.
- According to the shape of the head, there are hexagonal heads, round heads, square heads, countersunk heads, and so on. Generally, countersunk heads are used in places where the surface after connection is required to be smooth without protrusions, because the countersunk head can be screwed into the part. The head can also be screwed into the part. The tightening force of the square head can be larger, but the size is large. The hexagon head is the most commonly used.
In addition, in order to meet the need of locking after installation, there are holes on the head and holes on the rod. These holes can prevent the bolt from loosening when it is vibrated. Some bolts without threaded polished rods are made thinner, called thin waist bolts. This kind of bolts is conducive to the connection of variable forces. There are special high-strength bolts on the steel structure. The head will be larger. The size will also change.
Hex bolt manufacturers should carry out safety inspection functions in time to ensure that they function normally. In addition, there are special uses: T-slot bolts, the most used on machine tool fixtures, special shapes, and both sides of the head should be cut off. Anchor bolts are used to connect and fix the machine and the ground. There are many shapes, U-shaped bolts , As mentioned above and so on. There are also special studs for welding. One end has a thread and the other is not. It can be welded to the part, and the nut is directly screwed on the other side.
