WELCOME! WE'RE THE #1 SOURCE FOR TOP QUALITY, US-MADE PLASTIC KNOBS. Knobs which can be customized to meet virtually any product application. Made of Super Tough Nylon, our knobs are virtually indestructible and resistant to impact, most chemicals, temperature extremes and more. In other words, they are designed to stand up to "real world" conditions! Choose from any of our standard knob styles or let us custom manufacture a knob for you. Our standard knobs come with male or female threads in sizes up to 1/2" and most are also available with tapped inserts, threaded metal studs and reamed holes with setscrew. If our standard line doesn't meet your needs, A to Z Tool also offers you custom assembly, molding and machining capabilities.
