Ergonomically designed, these two families of thermoplastic clamping knobs are constructed from highly-durable glass-filled nylon. The families include a three-arm knob series and a bar knob series for ease of handling. With a matte finish, soft contours and strong clamping capabilities, these knobs are suitable for applications from consumer durables to industrial machinery. The products come with a projecting stud or a blind threaded insert and a selection of insert threads and sizes. The clamping knobs come complete with no tooling costs.
