    Our product range includes a comprehensive array of shapes, sizes, thread types and materials. Materials include glass filled nylon, duroplast, aluminium, and stainless steel. Knob shape and styles include lobe knobs, star knobs, thumbscrews, ball knobs, wing knobs, self assembly knobs and many more. Thread types include male threaded studs, female threaded inserts, push-fit for fitting on a plain shaft and self-assembly for fitting onto socket head cap screws.

    You may need the fine adjustment of a thumbscrew, or the extra clamping force of star knob or lobe knob, a ball knob or taper knob for fitting on a shaft, or a wing knob to quickly lock or unlock a collar clamp. Whatever the application, Rencol has the knob for you.
