RS PRO Black Multiple Lobes Clamping Knob, M8, Threaded Stud

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 multiple lobed handwheels – also known as star shaped handwheels – provide an easily-gripped shape, with a varying number of lobes depending on the grip and pressure required. The knobs are fitted with either a protruding screw insert (male), made from a combination of impact-resistant thermoplastic bodies and zinc-plated steel inserts, or a threaded brass recess (female). Zinc-plated steel and brass both provide wear resistance for the threads to ensure that the threads last throughout general use and are not easily damaged or sheared.
