What is a knurled thumb knob?

A knurled thumb knob is a small component designed to be easily turned by the thumb and fingers. It features a textured surface known as knurling, which consists of a pattern of ridges. The knurling provides improved grip and traction, making it easier to rotate the knob even when it's wet or oily. These knurled thumb knobs are commonly used in applications where quick adjustments or tightening are needed, such as on machinery, equipment, tools, and consumer products. They offer a convenient way to achieve fine-tuned control without the need for additional tools.
