RS PRO Black Multiple Lobes Clamping Knob, M8, Threaded Through Hole

These multiple lobed handwheels from RS PRO are an ergonomic shape to ensure user comfort, with a varying number of lobes depending on the grip and pressure required. The knob handles are made from impact-resistant thermoplastic bodies and male knobs are fitted with a protruding screw insert (male) of either stainless steel or zinc-plated steel. Female knobs and threaded though knobs have threaded inserts of zinc-plated or stainless steel. Zinc-plated steel and stainless steel both provide wear resistance for the threads to ensure that the threads last throughout general use and are not easily damaged or sheared.
