Bolts are indispensable in daily life and industrial production, and bolts are also known as industrial meters. It can be seen that bolts are widely used. There are many names of bolts, and everyone’s name may be different. Some are called screws, some are called screws, some are called standard parts, and some are called fasteners. Although there are so many names, they all mean the same. They are bolts. Bolt is a common term for fastener. The principle of bolts is to use physical and mathematical principles to gradually tighten the object parts, and make the object tilt in a circular rotation and friction. The application scope of bolts includes: electronic products, mechanical products, digital products, electrical equipment and electromechanical mechanical products. Bolts are also used in ships, vehicles, hydraulic engineering and even chemical experiments. Bolts are useful in many places. Especially precision bolts used in digital products. DVD, micro-bolt is used for cameras, glasses, watches, electronics, etc. General bolts for TV, electrical appliances, musical instruments, furniture, etc. For engineering, construction and bridges, use large bolts and nuts; Large and small bolts for transportation equipment, airplanes, trams and automobiles. Bolts play an important role in industry. As long as there is industry on the earth, the function of bolts is always very important.
Terminology relating to screws
1. Difference between screws, nuts,bolts, screws and studs: there are no screws and nuts in the standard. Screws are commonly known as “screws“. The nut shape is usually hexagonal , and the inner hole is internal thread, which is used to fit with the bolt and tighten the related parts. Nut is a common name, and the standard should be called “nut”.
The head of the bolt is generally hexagonal, and the rod has external thread. The screw is small, the head has flat head, cross head, etc., and the rod has external thread. The stud should actually be called “double-headed stud”, with external threads at both ends and a polished rod in the middle. The long end of the thread is used to connect with the deep hole, and the short end is used to connect with the nut.
2. Common English expression: Screw/Bolt/Fastener (bolt) (fastener)
3. Definition of thread: A thread is a shape with a uniform spiral bulge on the external or internal surface of a solid.
Thread action
1. Fastening and connection function: applicable to most screw products at this stage.
2. Transmission action (displacement action): such as micrometer used by QC to check dimensions. 3. Sealing function: such as connection and sealing of pipes.
