this screw is locked it self without any external forces
The locking mechanism is so the chord doesn't get detached if you move around a lot and accidentally pull on the chord. But you will have to screw in the locking chord. The non locking looks better.
Yes you can
the locking plug screws into the headphones, so you can't accidentally pull it out. you can also not screw it on.
To tune a guitar with locking tuners, first loosen the locking screw on each tuner. Then, tune the strings using the tuning pegs as usual. Once in tune, tighten the locking screw to secure the string in place. Repeat for all strings.
The locking cable allows you to screw on the cable to the headphones. So, for example, if you step on your headphones, the cable won't come out. The non-locking simply plugs into the headphones, much like a jack on your computer or iPod. I'd recommend the locking because you don't have to screw the headphones on.

Self-locking of a screw jack refers to the ability of the screw mechanism to prevent reverse motion when a load is applied, thus maintaining its position without additional support. This occurs when the friction between the screw and the nut is greater than the load's tendency to cause the screw to unwind. Self-locking is advantageous in applications where safety and stability are critical, as it reduces the risk of accidental lowering or movement of the load. However, it may also require higher torque to raise the load due to the friction involved.
The head locking screw on a microscope is used to secure the head or viewing tube in place to prevent it from moving or rotating during observation. This helps ensure stability and accuracy in viewing specimens under the microscope.
The efficiency of a screw jack can be increased by reducing friction between the screw and the nut through proper lubrication, using a finer pitch screw for smoother operation, and ensuring that the screw and nut are properly aligned to minimize binding. Additionally, using a larger diameter screw can help distribute the load over a larger area, reducing wear and improving efficiency.
To remove a screw with no head from wood, you can use a pair of locking pliers or a screw extractor tool. Grip the screw tightly with the pliers or use the extractor tool to twist and remove it from the wood.
loosen the locking nut while holding the screw with a screw driver, then you turn the screw clock wise until you feel resistance( like its touching something inside) then you back it off 1/4 turn, hold it in place while you tighten the locking nut , should be pretty close.
