What is a thumb screw? A screw drive that comes with either a tall headed or ridged (knurled) sides, or a key-like flat sided vertical head can be defined as a thumb screw. These screws can easily be tightened or loosened by hand without using any external drive. However, they are not ideally used for any structural applications.

Used in applications where a fastener is frequently adjusted with easy-grip textured head that allows adjusting and installation to be done simply by hand. A screw often used with screwless entry computer cases that only requires the users thumb and index finger to loosen or remove the screw.

A thumb screw actually acts like a bolt in most applications. When typically used, this blunt-nosed screw or bolt is fastened into a threaded hole and its ease of removal doesn’t require any external tool to assemble or disassemble any equipment.
Besides safety covers for electronic gadgets, thumb screws are also used in battery covers on many small electronic devices.A big advantage of the thumbscrew is that it does not fall out of the cover when the screw or bolt is loosened. This is because it uses a washer that is set in place to retain the screw in the cover. This feature does not allow the screw to fall off and get lost in the ground.
Certain screw designs come with a Philips screwdriver slot on the fastener head. This gives an option for the fastener to be tightened using a wrench and not simply by hand. These kinds of thumbscrews that come with a Philips screwdriver slots are widely used in high vibration applications like off-road vehicles and boats. In this case, they are not able to get loosened over time, or due to over usage or impact. On the other hand, knurled headed fasteners can be tightened using a pair of pliers that ensure an efficient torque.
