1.what are fine thread bolt?
Generally, bolts with normal pitch are coarse-tooth bolts, and bolts with smaller pitch than normal are fine-tooth bolts.
2. What are the characteristics of thin threaded bolts?
The small spiral angle of fine teeth is beneficial to the self-locking of the thread, so fine teeth screws are generally used in occasions that need to prevent loosening. The thread pitch of fine thread is small, and the number of threads screwed in is more on the same thread length, which can reduce the fluid leakage, so it is used in occasions that need to be sealed. Fine thread should also have the advantage of small pitch, which can play a fine-tuning role. Fine-tooth screw has good self-locking ability, large bottom diameter and good static load capacity.
3. What are the applications of fine threaded bolts?
Fine-thread bolts are usually used in situations requiring high strength of fasteners. Because fine thread is shallower than coarse thread and its thread diameter is larger, its thread strength is higher than that of coarse thread with the same nominal specification. In addition, fine thread can be used for fine adjustment.
