    Vibration-Resistant Threaded-Stud Knobs

    Bonded to the stud is an acrylic adhesive that adds friction to resist loosening from vibration. Use these knobs to position, tighten, and hold fixtures, equipment, and machinery. They mount into a threaded hole. The studs have an outer layer of zinc that prevents the steel from rusting in wet areas. Made of plastic, all of the knobs resist oil, grease, and solvents.
