JIC Male Thread manufacturers believe that ordinary threads can be divided into coarse and fine threads, and the same nominal diameter can have multiple pitches, among which the largest pitch is called coarse thread, and the rest are fine thread.
JIC Male Thread manufacturers believe that ordinary threads can be divided into coarse and fine threads, and the same nominal diameter can have multiple pitches, among which the largest pitch is called coarse thread, and the rest are fine thread.
1. JIC Male Thread manufacturers found that the helix angle of the fine thread is smaller, which is more conducive to the self-locking of the thread, so the fine thread is generally used where anti-loosening is required.
2. The pitch of the fine-pitch thread is small. On the same thread length, the number of threads screwed in is more, which can reduce fluid leakage, so it is used in occasions that require sealing.
3. JIC Male Thread manufacturers feel that the same length of coarse thread has fewer teeth, and the cross-sectional size of each tooth is larger, which is better in force, and is more suitable for bearing greater tension and impact.
4. The fine-tooth thread should also have the advantage of small pitch, which can play a role in fine-tuning.
JIC Male Thread manufacturers believe that coarse thread can be understood as the thread when the thread pitch P is selected to the maximum allowable value when the thread specification is determined. For example, for M12 thread, the pitch can be 1.75. 1.5 and 1. M12×1.75 is coarse thread, M12×1.5. M12×1 is fine thread. For coarse threads, the pitch item can be omitted.
