Classification and use of fasteners

Fasteners are a type of device used to connect, fix and seal parts, mainly including bolts, nuts, washers, pins and so on.
According to the use and shape characteristics, fasteners can be divided into the following categories: bolts and nuts: bolts are cylindrical parts with external threads, and nuts are parts with internal thread holes used with bolts. They are mainly used to connect components that need to be disassembled for maintenance, and are commonly found in various mechanical equipment, automobiles, ships, etc.
Stud and sleeve: A stud is a cylindrical part with internal threads, and a sleeve is a sleeve part with external threads. Studs and sleeves are commonly used to strengthen or repair the strength of threaded connections and are widely used in the assembly of metal structures and mechanical equipment.

Nylon lock: Nylon lock is a special shape washer made of nylon material, which has the function of anti-sliding, anti-vibration and locking. They are commonly used to connect lightweight equipment that requires loosening or vibration resistance, such as appliances, meters, etc. Spring: A spring is a part with elastic deformation ability, which can be used to connect, limit, cushion and adjust the force of the device.
According to the different shape, the spring can be divided into compression spring, tensile spring, torsion spring, etc., which is widely used in machinery, electronics, automobiles and other fields.
Pins and pins: Pins and pins are fasteners that can withstand shear forces and are often used to connect members for axial or lateral positioning. They are mainly used to connect parts that need to be disassembled frequently, such as furniture, doors and Windows.
In addition, there are some special types of fasteners, such as gaskets, flanges, pin structures, etc., which each have their own special application scenarios. In general, fasteners play a vital role in various industries to ensure the safe and reliable operation of equipment.
