Bolt Shape Introduction
Introduction to the shape of hot-dip galvanized bolts, bolts: mechanical parts, cylindrical threaded fasteners with nuts. It consists of two parts: head and screw (cylindrical body with external thread)
A type of fastener consisting of a type of fastener that needs to be mated with a nut. The countersunk head is generally used where the surface is lubricated and not protruding after the connection, 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 scale is large. In order to meet the needs of locking after installation, there are holes in the head and holes in the rod.
These holes prevent the bolt from loosening when subjected to vibration. Some bolts have thinner smooth rods without threads, which are called thin-waist bolts.
This type of bolt facilitates variable force combinations. There are special high-strength bolts on the steel structure, the head will be larger, and the size will also change. Others with special purposes: for T-slot bolts, most commonly used for machine tool fixtures,
The shape is special, and the sides of the head should be cut off. Anchor bolts are used to connect and fix the machine to the ground. There are many shapes. U-bolts, as above. There are a lot more.
There are also special studs for welding. One end is threaded, the other is not. It can be welded to the part and the nut screwed directly on the other side.
