The difference between right thread and left thread

Screws are a common fastener. The working principle of a screw depends on the thread design on its surface, and the thread can be divided into two main types: right thread and left thread.

Right thread screws, also known as common thread screws, are designed to be screwed in clockwise, that is, when we use tools such as screwdrivers or wrenches to turn the screw clockwise, the screw can be smoothly screwed into the nut. Right thread screws are widely used in furniture, electrical appliances, mechanical equipment and other fields.

Left thread, opposite to the positive thread. The thread design of the left thread screw is to screw in counterclockwise. In situations where it is necessary to prevent the screw from loosening, such as in vibrating equipment or high temperature environments, the left thread screw can provide a better tightening effect. The force generated by the vibration will cause the left thread to vibrate and tighten, making the screw produce a self-locking effect, effectively resisting vibration and loosening. Therefore, left thread screws are often used in high-precision and high-requirement fields such as aerospace and automobile manufacturing.

The right and left thread designs of screws meet the fastening needs in different scenarios. Understanding the characteristics of these two threads will help us be more accurate in selecting and using screws.
