RS PRO Phenolic Star Male Handwheel Knobs

Knobs are used in a wide variety of applications in our day-to-day lives and perform many functions, from being used as fixed handles to being used to tighten, loosen, adjust, clamp and push other components or pieces of equipment. They are used in various applications, from industrial and construction machinery to audio and visual equipment.

These star shaped handwheels – also known as multiple lobed handwheels– provide an easy-to-grip shape. This variation features four lobes, but other models will have varying numbers depending on the grip and pressure required. The knobs are fitted with a protruding screw insert (male) made from a combination of wood-filled impact-resistant thermoplastic bodies and zinc-plated steel inserts. Zinc-plated steel provides wear resistance for the threads to ensure that the threads last throughout general use and are not easily damaged or sheared.
