Custom Bolt is a general term for a type of machine parts adopted when two or more parts (or components) are fastened and connected to form a group. Also called standard parts on the market.
It usually includes the following 12 types of parts:
1. Bolt: A type of fastener composed of two parts, a head and a screw (cylinder with outer ribs). It needs to be combined with a nut to fasten and adjoin two parts with through holes. This type of connection is called bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.
2. Stud: There is no head, the only type of fastener with ribs on both ends. When connecting, one end of it must be screwed into the part with inner rib hole, and the other end must be passed through the part with through hole, and then the nut is screwed on, even if the two parts are firmly connected to form a group. This type of connection is called a stud connection, which is also a detachable connection. It is mainly used in places where one of the connected parts has a large thickness, requires a loose layout, or is not connected by bolts due to frequent disassembly.
What is involved in the use of Stud Suppliers fastener standard parts?
3. Screws: It is also a type of fasteners composed of two parts: head and screw. According to their use, they can be divided into three categories: machine screws, set screws and special purpose screws. The mechanical screw is mainly used for the fastening connection between a part with a tight rib hole and a part with a through hole, and no nut is required (this kind of connection is called a screw connection, which is also a detachable connection; Together with the nut, it is used to fasten the connection between two parts with through holes.) The set screw is mainly used to secure the relative position between the two parts. Particularly useful screws, such as eyebolts, etc., are used for hoisting parts.
4. Nut: with inner rib hole, the shape is generally flat hexagonal column shape, there are also flat square column shape or flat cylindrical shape, common bolt, stud or machine screw, used to fasten and adjoin two parts, make It becomes a group.
5. Self-tapping screws: similar to mechanical screws, but the ribs on the screw are common self-tapping screws. It is used to fasten and adjoin two thin metal components to make them into a single body. Small holes must be made on the components in advance. Because these screws have high hardness, they can be indirectly screwed into the holes of the components to make them Form the echoing inner ribbing. This type of connection is also a detachable connection.
6. Wood screw: It is also similar to the machine screw, but the rib on the screw is a common wood screw thread, which can be indirectly screwed into the wooden component (or part) to use a metal (or non-metal) with a through hole. The parts are firmly connected to a wooden component. This type of connection also belongs to the connection that can be dismantled.
7. Washer: A type of fastener with an oblate ring shape. Placed between the support surface of bolts, screws or nuts and the outline of adjacent parts, it plays a role in increasing the area of the adjacent parts, reducing the unit area and protecting the adjacent parts from being damaged; another type of elastic washer , Can also play a role in prohibiting the nut from loosening.
