Wherever a right hand screw would be prone to unscrew itself.
A screw clamp is something that is used to put a screw in place. There are hand screw clamps where you use your hand to tighten the screw.
The impeller screw is typically a right-hand thread, meaning it tightens clockwise and loosens counterclockwise. However, in some specific applications or designs, it may be left-hand threaded. It's essential to consult the manufacturer's specifications for the particular impeller in question to confirm the thread type.
A screw may be used to fasten materials such as wood or metal to each other. Sometimes, a screw is left protruding from the surface of a wall, to be used as a portrait-hanger.
A screw operates by a raised ledge which proceeds up the shaft of the screw in a spiral. This raised ledge is called the thread of the screw. Since the spiral can either proceed in a clockwise or counterclockwise manner, we distinguish between right-hand thread screws (counterclockwise as viewed from above) and left-hand thread screws (clockwise).
Left-hand threaded refers to a type of screw or bolt that is designed to tighten in a counterclockwise direction, rather than the standard clockwise motion associated with right-hand threads. This is often used in applications where the normal rotational motion might cause a right-hand threaded fastener to loosen, such as in certain machinery or bicycle pedals. The left-hand thread is typically marked or indicated to prevent confusion during installation.
Propellers are either "Left Hand" or "Right Hand". When the propeller is viewed from the blade edge or its side, the blade is angled upward to the left (Left Hand) or upward to the right (Right Hand). See illustration. enlarge Regards, Mike Leary misticmike@googlemail.com
