I just found some flashlights thread have 8 circle of solenoid coil (like photo 3.1). The Screw pitch is relatively narrow
And some flashlight has only 4 circle of solenoid coil.(like photo 2.1); And the Screw pitch is relatively larger.
And some flashlight the thread in Square cut (like photo 1.1)
Some thread in standard triangular cut.(like photo 4.1)
Even in one flashlight the head thread and tail thread is different. See the below photo 6.1 "Tail thread" is square cut and biger Screw pitch.
And the head therad is standard triangular cut (see photo 6.12) and relatively narrow screw pitch
About the thread,Is there any one know what kind of thread is good for flashlight? Do you think the thread type is very importand to a flashlight ? IMO . The square cut and narrow screw pitch will be good for the flashlights.Is there any different thread here in the lights?
Thanks
