Standard fasteners are divided into twelve categories. When selecting fasteners, they should be determined according to their usage situation and function.
 
 
1. Bolts: Bolt remanufacturing is widely used in detachable connections, generally with nuts (usually plus a washer or two washers) supporting the use.
 
2. Nuts: Nuts and bolts to match the use.
 
3. Screws: Screws are usually used alone (sometimes with gaskets). They usually play a tightening or fastening role. They should be screwed into the internal threads of the body.
 
4. studs: studs are mostly used to connect one of the connected parts with a large thickness. They need to be used in places where the structure is compact or where the bolt connection is not suitable because of frequent disassembly. The stud usually has threads at both ends (single stud with threads at one end). Usually one thread is firmly screwed into the part body, and the other end is matched with the nut, which plays the role of connection and fastening, but it also has the role of fixed distance to a large extent.
 
5. Wood screw: Wood screw is used to screw into wood, which plays a connecting or fastening role.
 
6. Self-tapping screw: The working holes matching self-tapping screw need not be tapped beforehand, while the self-tapping screw is screwed in, the internal thread is formed.
 
7. Gasket: The gasket is placed between the supporting surface of bolts, bolts and nuts and the supporting surface of the workpiece to prevent loosening and reduce the stress of the supporting surface.
 
8. Baffle ring: Baffle ring is mainly used to locate, lock or stop parts in the shaft or hole.
 
9. Pins: Pins are usually used for positioning, connecting or locking parts, and as overload shearing elements in safety devices.
 
10. Rivet: The rivet has a head at one end, and the rod has no threads. When in use, the rod part is inserted into the hole of the connecting part, and then the end of the rod is riveted to play a connecting or fastening role.
 
11. Connecting pairs are combinations of bolts or bolts or self-tapping bolts and gaskets. After the washer is mounted on the screw, it must be able to rotate freely on the screw (or bolt) without falling off. It mainly plays a tightening or fixing role.
 
12. Other main contents include welding studs and so on.
