For monitoring the number of shaft turns on instrumentation, these knobs have easy-to-read scales or digits for quick and accurate readings. Use them on devices with round shafts. To secure these knobs in place, tighten the set screw.
Plastic knobs are a lightweight alternative to metal. They resist oil, grease, and solvents.
Aluminum knobs have mild corrosion resistance, are lightweight, and are nonmagnetic.
