Is it clockwise or counterclockwise to loosen a screw?

[LeBriella]

Loosening a screw is counterclockwise. Below are relevant introductions: Standard: Screws are tightened clockwise and loosened counterclockwise. For rusted screws, do not force them to prevent rounding off the hexagonal edges of the screw, breaking the screw, or damaging the wrench. In such cases, you can gently tap the wrench handle with a hammer to vibrate and loosen the rusted screw. Definition: A screw is a tool that utilizes the physics and mathematics principles of the inclined plane, circular rotation, and friction to gradually fasten mechanical parts. Screw is the general term for fasteners in daily colloquial usage. Screws play a crucial role in industry; as long as industry exists on Earth, the function of screws will always be important. Screws are a collective invention in human production and life over thousands of years. In terms of application fields, they are considered humanity's first major invention.

Generally, screws are loosened by turning them counterclockwise. Having worked on cars for many years, I've encountered numerous issues like this because most screws are designed with right-hand threads—clockwise tightens them, while counterclockwise loosens them. In practice, if you turn clockwise, the screw may actually tighten further or seize, especially on rusty old components, which can easily lead to thread damage or tool slippage. My advice is to first use the appropriate wrench to gently turn counterclockwise, applying more force only when you feel it loosening. If it doesn't budge, spray some rust penetrant for lubrication, wait a few minutes, and try again. Remember not to apply excessive force blindly, as this can easily strip the screw head. For beginners, memorizing the phrase 'lefty-loosey, righty-tighty' is very handy—turning left (counterclockwise) means loosen, and turning right (clockwise) means tighten. Regular tool maintenance is also crucial to avoid reduced effectiveness due to wear. These small tips have saved me a lot of time and reduced repair costs.

Turning counterclockwise to loosen screws is standard practice. Since I often assemble furniture at home, I rely on this rule when screws get stuck. It's just like opening a bottle cap—counterclockwise to loosen, clockwise to tighten. If the screw won't budge counterclockwise, it might be rusted. Try using some WD-40 for lubrication or gently tapping the screw head before trying again. Always use the right-sized screwdriver to avoid stripping the screw head. This design is common in daily life to minimize the risk of mistakes. Remember the phrase 'lefty loosey, righty tighty'—left means counterclockwise. Before disassembling, it's best to clean the screw and surrounding area, as dust buildup can make removal difficult. I've encountered some exceptions, like certain bicycle screws, but 99% of the time, counterclockwise does the trick. Protect your fingers during the process by wearing gloves to avoid cuts.

Turning counterclockwise loosens screws, which is a basic repair knowledge. When teaching my child to fix things, I always emphasize this rule: most screws are right-handed, so turning counterclockwise (left) loosens them, while turning clockwise (right) tightens them. It's important to confirm the direction during operation. Apply gentle counterclockwise force with a wrench, and if it doesn't budge, don't force it—check if the tool size is incorrect or if debris is stuck. For safety, avoid injuring your hands and keep the workpiece steady. Simple tasks become habits with repeated practice.
