Large and rugged, our Plastic 4-Prong Knobs are excellent for applications requiring high torque or heavy-duty clamping. The efficient design makes them easy to grasp and turn.  Decorate your knob with a pad printed or hot stamped logo or design for a truly unique look.  With Four Prong Knob diameters that range from 1 3/4” to 2 1/2”, we have a knob that is perfect for any application. Our Plastic Four Prong Knobs are available in male, female thru, female blind, and female locking versions with either inch or metric threads.  Our plastic knobs are molded using Polypropylene, nylon, or ABS, which makes them up to twice as impact resistant as similar phenolic knobs.  Custom inserts, custom hubs, and RoHS compliant parts are available upon request.  Can’t find the Plastic 4-Prong Knob you’re looking for?  Contact Innovative Components today to learn about our custom molding options.
