Set-screw knobs are designed to fit a flatted 1/4" round shaft. A 1/16" hex key is required to loosen or tighten the knob. Make sure the set screw is tightened against the flatted side of the shaft. These knobs can be ordered with or without the tool.

Press-fit knobs are designed to fit on a 1/4" splined shaft. These knobs will take a fair amount of force to remove. Pull straight off, do not use tools.
