What are the advantages of stainless steel fine thread screws?

The thread of stainless steel fine pitch screw is fine pitch, and the distance between adjacent outer diameters is generally closer than that of coarse pitch. When marking fine thread, the pitch should be marked to show the difference from coarse thread.

Stainless steel fine screws have the following advantages: the spiral angle of the fine-tooth is smaller, which is more conducive to the self-locking of the thread, so the fine-tooth is generally used in places that need to prevent loosening. The thread pitch of fine thread is small. In the same thread length, more threads are screwed in, which can reduce fluid leakage, so it is used in occasions that require sealing. The fine thread should also have the advantage of small pitch, which can play a fine-tuning role. The fine teeth have strong self-locking ability, large bottom diameter and strong static load capacity. In addition, the tightening torque of the fine teeth is smaller. The steel grade has a certain relationship with the pre-tightening capacity, and the fine teeth are smaller under the same pre-tightening force.

The thread self-locking of stainless steel fine pitch screws is higher than that of coarse pitch threads. The pre-tightening force is also higher, the temperature is higher, and the vibration is larger. The more important parts can choose fine-pitch threads. Optional.
