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.
