Threaded-Hole Ball Knobs



Install these traditional, easy-to-grip ball knobs on a threaded stud. They're good for control levers and push-pull rods.
Stainless steel knobs have excellent corrosion resistance, making them the best choice for harsh environments. They also have good chemical resistance.
Aluminum knobs have mild corrosion resistance, are lightweight, and are nonmagnetic.
Brass knobs have good corrosion resistance and are nonmagnetic.
Plastic knobs are a lightweight alternative to metal. They resist oil, grease, and solvents. Phenolic has good scratch resistance. Polypropylene has good impact resistance.
