Black Control Knob for 6.35mm Round 0.25" Inch Shaft Flat Grub Screw Fixing

$3.37

Shipping to United States: $13.69


This is one item of new control knob with an ordinary flat-bladed grub screw fixing. All sizes are suitable for true 1/4 inch or 6.3mm round shafts on electronic controls such as antenna tuning units, radio tuning and volume controls, guitar amps, valve amps, analogue synth controls etc.

The large ones are a good size allowing easy control of stiffer shafts with the extra leverage. They also make a good replacement for some broken cooker or gas barbecue knobs.

The material is phenolic resin with a steel metal insert in the centre on the two larger types and a brass centre on the smallest one. The grub screws are brass and can be tightened with an ordinary 2mm, for the smallest type, or 3mm flat blade radio screwdriver.
