Plastic universal knobs are unique and efficient. One knob fits multiple thread sizes and reduces SKUs. No tool required assembling these Self Tapping/Threading knobs. Universal knobs are also vibrant resistant and will stay on mating parts without glue or Loctite®. Since Universal Knobs have no metal insert, you won't have to worry about rust. Items are made with High Impact Polypropylene and available in both standard and Soft Touch. RoHS compliant parts are available upon request.
