Quick-Lock Threaded Through-Hole Knobs
Four Arm Grip
Five Arm Grip
Quick to install, position, and remove, these knobs have an angled hole that allows you to tilt the knob to slide it over threads, then straighten it to grip the threads and secure the knob. They provide a firm grip to position, tighten, and hold fixtures, equipment, and machinery.
Steel knobs are stronger than phenolic knobs.
Phenolic knobs are a lightweight alternative to steel knobs. They resist oil, grease, solvents, and scratches.
