Vibration-Resistant Threaded Through-Hole Knobs
Like locknuts, these knobs have a nylon insert that grips threads to resist loosening. Long shafts can thread through these knobs for mounting versatility. Use the knobs as a grip to position, tighten, and hold fixtures, equipment, and machinery. Made of plastic, all resist oil, grease, and solvents.

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. Phenolic knobs are scratch resistant. For impact resistance, choose polypropylene knobs.
