Metric screw studs are standardized fastening components designed to create secure, permanent, or semi-permanent connections between mechanical parts in metric-based systems. Commonly used in machinery manufacturing, automotive assembly, construction equipment, energy systems, and precision engineering, metric screw studs consist of a fully or partially threaded rod without a head, allowing nuts to be applied on one or both ends.

Linear motion components are at the heart of CNC machine performance, dictating precision, speed, and reliability.

Metric screw studs have become one of the most widely adopted fastening components across mechanical engineering, automotive manufacturing, construction systems, and precision equipment. These threaded rods—featuring a male thread on both ends or across the entire length—offer stability, alignment accuracy, and load-bearing capability that outperform many traditional fastening methods. As global industries move increasingly toward high-precision assembly and modular structures, the demand for robust metric fastening solutions continues to grow.

First of all, on the one hand, there will be a small amount of friction every time the screw rotates, and the friction will generate a lot of heat. If it is under the conditions of high frequency and high usage, the heat of this part is very large, so the heat of this part will cause the shell to There is a slight increase in the bearing position and the oil seal in the screw, which in turn causes microscopic displacement of the worm screw and the worm gear, causing instability, which will promote the occurrence of major conflicts, thus forming a vicious cycle.

Compared with the sliding screw pair, the driving torque is 1/3. Since there are many balls doing tumbling motion between the screw shaft and the screw nut of the trapezoidal thread screw, higher motion power can be obtained. Compared with the previous sliding screw pair, the driving torque is less than 1/3, that is, the power required to achieve the same movement effect is 1/3 of the rolling screw pair. Very helpful in saving power.

Lead screw products are easy to adjust in conjunction with the specific application to achieve the desired performance while keeping costs to a minimum.
