Clamping Knobs, Star Knobs, Wing Nuts & Screws, Thumb Screw

Clamping knobs are basic components that function by providing a strong grip or secure control through the use of elements such as texturing, knurling, lobes, or wings. Our selection of industrial knobs for clamping provides every possible option to suit any application.

We have textured nylon knobs, knobs with three to nine lobes (including four-pronged star knobs), triangular knobs, wing nuts and wing screws, and many styles of knurled knobs. Mounting options include threaded stud, tapped, tapped insert, tapped through hole, blind bore, and through bore. Materials include nylon plastic, phenolic plastic, polypropylene, technopolymer plastic, cast iron, steel, stainless steel, and aluminum. A broad range of sizes and configurations emphasize such aspects as ergonomic grip, quick release, sanitary applications, and more.
