Star knobs are a type of control knob that are designed for easy gripping and adjustment. They feature a star-shaped design, which allows for a secure grip and comfortable turning. Star knobs are typically made of durable materials such as plastic, metal, or wood, and come in a range of sizes and styles to suit different applications. They are commonly used in industrial machinery, woodworking equipment, and other tools that require quick and easy adjustments. The star-shaped design of the knob makes it easy to grip even with gloves on, and the shape also provides a visual cue for how much the knob has been turned. Star knobs often have a threaded insert that can be easily attached to a variety of threaded shafts, making them a versatile and widely used type of control knob.
