Does turning a car screw clockwise tighten or loosen it?
1 Answers
Turning a car screw clockwise tightens it. Below is relevant information about car screws: Design reason: The majority of screws are designed with right-hand threads due to ergonomic principles. The speed direction relative to the rotation axis follows the right-hand rule, and over 90% of people are right-handed, making it more convenient for the majority. Additionally, right-hand threads are easier to manufacture, especially in large-thread turning processes. Important notes: Screws are critical fasteners in automobiles. The tightness and tightening sequence of these fasteners are extremely strict; otherwise, they may pose safety hazards.
