What parts are solar fasteners made of

Components
It usually includes the following types of parts
1. A type of fastener consisting of a head and a cylinder with an external thread on the screw should be used with a nut to fasten and connect two parts with through holes. This form of connection is called a bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.
2. A type of fastener in which the stud has no head and only has external threads on both ends. When connecting, one end of it must be screwed into the part with internal threaded hole and the other end through the part with through hole and then screw on the nut even if the two parts are tightly connected as a whole. This form of connection is called a stud connection and is also a detachable connection. It is mainly used for occasions where one of the connected parts has a large thickness, requires a compact structure, or is not suitable for bolt connection due to frequent disassembly.
3. The screw is also a type of fastener consisting of a head and a screw. According to the purpose, it can be divided into three types of machine screws, set screws and special-purpose screws. Machine screws are mainly used for a fastened connection between a part with a fixed threaded hole and a part with a through hole. No nut is required. This type of connection is called a screw connection and is also a detachable connection. It can also be used with a nut. Fastening connection between two parts with through holes. Set screws are mainly used to fix the relative position between two parts. Special purpose screws, such as eyebolts, are used for hoisting parts.
4. Nuts with internal threaded holes are generally in the shape of flat hexagonal cylinders, and there are also flat square cylinders or flat cylinders with bolts, studs or machine screws used to fasten and connect two parts to make them a whole.
Special categories of nuts
High strength self-locking nut
It is a classification of self-locking nuts with high strength and high reliability. Few domestic manufacturers of such products are mainly used for the introduction of European technology as a prerequisite for road construction machinery, mining machinery, vibration machinery and equipment.
Nylon self-locking nut
Nylon self-locking nut is a new type of high anti-vibration and anti-loosening fastening parts, which can be used in various mechanical and electrical products with a temperature of -50100 ℃. Aerospace, aviation, tanks, mining machinery, automobile transportation machinery, agricultural machinery, textile machinery, electrical products and various types of machinery have a sharp increase in the demand for nylon self-locking nuts. This is because its anti-vibration and anti-loosening performance is much higher than other It is a kind of anti-loosening device and the vibration life is several times or even dozens of times longer. At present, more than 80% of the accidents of machinery and equipment are caused by loose fasteners, especially in mining machinery. The use of nylon self-locking nuts can prevent major accidents caused by loose fasteners.
5. The self-tapping screw is similar to chipboard screw Wholesale the machine screw, but the thread on the screw is a special self-tapping screw thread. It is used to fasten and connect two thin metal components to make them into a single piece. Small holes need to be made in advance. Because of the high hardness of this kind of screw, it can be directly screwed into the hole of the component to form a corresponding internal thread in the component. . This form of connection is also a detachable connection.
