Active joint bolt is a type of fastener composed of a screw and a nut, characterized by one or both ends of the screw having a circular active joint.
The advantage of the articulated bolt lies in its flexibility. The articulated joint allows for a certain degree of angle adjustment during installation and connection, making it convenient to meet different installation requirements. It is commonly used in situations that require frequent disassembly and installation, such as the connection of some mechanical equipment, the fixing of protective devices, etc.
From a material perspective, common ones include carbon steel, stainless steel, etc. When making a choice, it is necessary to comprehensively consider factors such as the corrosiveness of the usage environment, load-bearing requirements, and cost.
Its specifications are usually determined based on the diameter and length of the screw, as well as the type and size of the thread.
The common specifications and models of articulated bolts are usually distinguished based on their screw diameter and length.
Common screw diameters include M6, M8, M10, M12, etc.
There are multiple options for length, such as 20mm, 30mm, 40mm, 50mm, etc. The specific length can be determined according to actual needs.
In addition, the pitch and accuracy of the threads may also vary. For example, the pitch of M8 may be 1.25mm or 1.0mm, etc.
It should be noted that different manufacturers and application scenarios may have some special specifications and models. In practical selection, the appropriate specifications and models of the joint bolts should be determined based on specific usage requirements and installation conditions.
The common materials for articulated bolts are as follows:
1. Carbon steel: It has high strength and hardness, relatively low price, and is widely used in general mechanical and structural connections.
2. Stainless steel: such as 304 stainless steel and 316 stainless steel, have good corrosion resistance and are suitable for humid, corrosive environments or occasions with high hygiene requirements.
3. Alloy steel: It has better strength and toughness, and can meet some special requirements for high strength and wear resistance.
4. Copper: It has good conductivity and thermal conductivity, and is used in some special electrical or situations where conductivity is required.
5. Aluminum alloy: Lightweight and corrosion-resistant, commonly used in lightweight structures with weight requirements.
