Oblong Hole for Tilt-and-Slide Operation - Northwestern Tools quick acting knobs feature an oblong hole that allows you to tilt and slide the knob onto a stud for rapid engagement. To engage the threads, straighten the knob and turn it clockwise. To remove the knob, tilt and slide it off—no need to unthread completely. This quick-action design is ideal for applications requiring frequent access, but these knobs are NOT suitable for use with vibrating equipment due to the oblong hole design. Steel construction with black finish provides durability and professional appearance.
