Product Details
RS PRO Black Nylon Knurled Thumbscrew 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.
From RS PRO comes these knurled thumbscrew knobs, also known as grip knobs, which are ideal for limited space environments and applications. These knobs have a detailed thumbscrew head for extra grip, ensuring user comfort and easy usability.
With such a low-profiled shank, these knobs sit almost flush against their application, preventing any accidental knocks and preserving space. The high-impact-resistant thermoplastic of which these knobs are made additionally reduces any wear & damage these knobs may experience, and the zinc-plated steel studs are resistant to corrosion, protecting the thread during wear & tear.
Male thumbscrew knobs: M4 x 10mm (RS 8304145), M6 x 15mm (RS 8304158).
