Structural characteristics of fully threaded studs

Fully threaded studs are a common type of connector that has a certain mechanical connection and fixing effect. The structural characteristics of this stud include the following aspects.

1、 Structural form

A fully threaded stud is composed of two parts: a nut and a screw, and the screw is densely covered with threads. Its characteristic is that the entire screw has threads on its circumference, and tightening force is applied between the nut and the screw to achieve mechanical fixation.

2、 Material selection

The material of fully threaded bolts should be high-strength steel to meet its mechanical performance requirements. In addition, its strength, toughness, and corrosion resistance also need to be considered.

3、 Mechanical calculations

The axial tensile force generated by fully threaded bolts during the application of preload can cause tensile deformation of the screw and nut, as well as generate shear force and pressure. The magnitude, direction, and location of these forces require mechanical calculations.

4、 Apply preload

During the installation process, appropriate preload must be applied to ensure the reliability of the stud. To achieve the purpose of preloading, a torque wrench is generally used for adjustment. By applying force to it, fasteners such as nuts, studs, and washers can correctly transmit pressure, thus forming a tight connection between their contact surfaces.

5、 Connection method

There are various connection methods for fully threaded studs, such as universal threaded connections, flange connections, flat head connections, etc. In addition, bolts and nuts can be used for connection, or attachments such as spring oscillators and gaskets can be used for connection.

6、 Application field

Fully threaded studs are widely used in fields such as construction, aviation, automotive, mechanical manufacturing, and power. In terms of architecture, it can be used for connecting steel structures, bridges, tunnels, subways, high-rise buildings, etc. In the fields of automobiles and mechanical manufacturing, it is mainly used for connecting components such as engines, transmissions, and chassis.

7、 Fixed effect

Fully threaded studs have good fixation effect, as they can fix the splines on the shaft, thereby avoiding rotation or wear of the shaft. The advantages of easy installation, reliable use, long service life, and low maintenance cost are also the reasons why it is widely used by people.
