The difference between parcial thread and full thread screws and the precautions for use

The difference between parcial thread and full thread screws and the precautions for use

Definition and difference of parcial thread screws and full thread screws

A screw is a type of mechanical connector that has a spiral thread and a notched head. According to the length of the thread, screws are divided into half teeth screws and full teeth screws. The thread length of parcial thread screws is shorter than that of full thread screws, and the head is smaller than that of full thread screws, and it is usually used to connect thin sheets or thin parts whose thickness does not exceed the thread length. The thread length of the full thread screw is longer than that of the parcial thread screw, and the head is larger than that of the parcial thread screw, and it is often used for thick plates and thicker parts with higher connection density or need better connection strength.

Second, use precautions

  1. Confirm the connection materials and requirements: when selecting screws, you must first confirm the material to be connected and its requirements to determine which kind of parcial threador full threadscrews is more suitable.
  2. Confirm the specification and size of the screw: When selecting the specification of the screw, pay attention to choosing the appropriate diameter and length to ensure the connection is firm and stable.
  3. Confirm the material and surface treatment of the screw: according to the material and requirements of the connection to choose the appropriate screw material, such as stainless steel, carbon steel, etc., and pay attention to the surface treatment of the screw to ensure the service life and use effect.
  4. Pay attention to the installation force and installation direction: When installing the screw, pay attention to whether the screw installation force is appropriate and whether the screw installation direction is correct to ensure the connection is firm and stable.
  5. Pay attention to the tightening strength of the connection screw: when tightening the screw, it is necessary to control the tightening strength, not too tight or too loose, so as not to affect the connection effect and service life, but also pay attention to the tightening sequence.
