Rough pole double studs with fine pitch is a relatively thick metal rod with fine threads at both ends. It comes in a wide range of specifications, with thread diameters ranging from a few millimeters to tens of millimeters, and the length can also be selected according to actual needs.
The characteristic of rough pole double studs with fine pitch is the coarse rod structure. Compared with ordinary studs, coarse rods can enhance the overall strength and rigidity and are less likely to deform when subjected to heavy loads. The pitch of fine-threaded threads is small, and the gap between each turn of the thread is smaller. When turned, it can generate greater friction, and it is less likely to loosen after being tightened.

Rough pole double stud with fine pitch is more commonly used in industries such as mechanical manufacturing, aerospace, and precision instruments. Assembling high-precision equipment in mechanical manufacturing; Fixed aircraft components in the aerospace field; In the production of precision instruments, to ensure the stability of parts, this type of stud is always needed to guarantee the reliability and stability of the connection.
Rough pole double studs with fine pitch are used to fix the key components of large mechanical equipment. In factories, large-scale mechanical equipment such as heavy-duty machine tools and large compressors are often installed and used. To install the spindle box of the heavy-duty machine tool, screw one end of the stud into the threaded hole of the machine tool bed and pass the other end through the installation hole of the spindle box, then screw on the nut.

These rough pole double studs are used for mold manufacturing and installation. In the mold manufacturing industry, when making injection molds, die-casting molds, etc., they are used to fix the various modules of the molds. Connect the upper and lower molds of the mold. Screw one end of the stud into the threaded hole of the lower mold and pass the other end through the upper mold. Then screw on the nut.
