Unscrewing a screw seems like an easy task, but it can be tricky if you don't know which way to turn the screwdriver. The direction in which you turn the screwdriver depends on the type of screw you are dealing with. This article will guide you on which way to unscrew a screw.
Righty Tighty, Lefty Loosey
The most common rule of thumb is "righty tighty, lefty loosey." This means that you turn the screw clockwise to tighten it and counterclockwise to loosen it. This rule applies to most screws, including Phillips and slotted screws.
Reverse Thread Screws
However, there are some screws with reverse threads. These screws have a left-hand thread, which means that you turn them counterclockwise to tighten them and clockwise to loosen them. Reverse thread screws are commonly found in bicycle pedals and some power tools.
Hex Screws
Hex screws, also known as Allen screws, have a hexagonal-shaped recess instead of a slotted or Phillips head. To unscrew a hex screw, you need to turn the Allen wrench counterclockwise. The rule "righty tighty, lefty loosey" does not apply to hex screws.
Security Screws
Security screws have a unique shape that requires a special tool to unscrew them. These screws are often used to prevent tampering, theft, or unauthorized access. If you encounter a security screw, you need to use the appropriate tool to unscrew it.
Conclusion
Knowing which way to unscrew a screw is essential for any DIY project or repair work. Always remember the rule "righty tighty, lefty loosey" as it applies to most screws. However, be aware of reverse thread screws, hex screws, and security screws, which require a different approach. By following these guidelines, you can unscrew any screw with ease.
