A Better Square-Drive Knob

Get a grip on that CO2 bottle with Pro-werks’ Bottle Knobs. This lightweight, all-American solution features deep notches for positive grip and a comfortable touch. Of course, they match the rest of Pro-werks’ line of Easy Turn Fill Caps and Knobs also!

We precision-machine each knob on one of our multi tasking MAZAK CNC machining centers. We start with American melt, aircraft-grade 6061-T6 aluminum; then finish them in our trademark Pro-werks colors: anodized black, red, blue, or silver; or our popular micro-polished aluminum finish.

These trick knobs are available in two different square drive sizes to accommodate valves found on most CO2 bottles. For proper fit, remove your original knob and measure the "square drive" across the flats before ordering.

Crafted with pride in Mears, Michigan, USA
