China thread rods wholesale customized

Thread Rod

Our threaded rods have a 40% increase in load carrying capacity compared to threaded rods of the same specification; they have expanded the range of use of the screw; they are easy to operate and have low prices. The full length of the threaded rod body has rolling continuous threads, and the overall length is equal; the fastening end is provided with a prestressed gasket and a ball-shaped nut.

Threaded rod requirements for materials:

It can be seen from the extrusion process that the screw works under high temperature, certain corrosion, strong wear and high torque. Therefore, the screw must:

1. High temperature resistance, no deformation under high temperature;

2. Wear resistance and long life;

3. Corrosion resistant, the material is corrosive;

4. High strength, can withstand high torque, high speed;

5. Have good cutting performance;

6. The residual stress is small after heat treatment, and the thermal deformation is small.

Type of threaded rod thread

1. Triangular thread: the tooth angle is 60°, the self-locking property is good, the root is thick, and the strength is high, which is used as the connecting thread;

2. Rectangular thread: the tooth angle is 0°, the transmission efficiency is the highest, but the root strength is low, the manufacturing is difficult, the centering precision is low, the gap after wear is difficult to compensate, and the application is less;

3. Trapezoidal thread: the tooth angle is 30°, the root strength is high, the neutrality is good, the processing is easy, the transmission efficiency is high, the gap can be adjusted after wear, and it is often used as a bidirectional transmission thread;

4. Serrated thread: The working surface has a bevel angle of 3°, the non-working surface has a bevel angle of 30°, high efficiency, high root strength, and is used as a one-way transmission thread.
