Knurled Thumb Knobs


Manufactured from Thermoplastic with a matt finish and brass female inserts.

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 brass female inserts are resistant to corrosion, protecting the thread.


Female thumbscrew knobs: M4 (RS 6319085), M5 (RS 6319108), M6 (RS 6319091).


Features & Benefits


  • Thermoplastic body and brass female insert

  • High tensile strength yet light in weight

  • Low shank height for space-restricted applications

Applications


The knurled sides provide additional grip for the user, while the low shank height allows these knobs to be used in space-restricted areas. Possible applications include:


  • Industrial machinery

  • Electronics enclosures

  • Lighting equipment

  • Audio equipment

  • Office and domestic furniture
