  • MDI knobs are available with either inserts or studs in any thread size, length or depth, including metric.
    Molded from reinforced polymer to provide maximum resitatnce to torque, they also feature a shoulder that prevents clamping pressure from relaxing over time.
  • PLASTIC MATERIALS Our standard knobs are produced in fiberglass reinforced nylon, an extremely tough material that provides superior resistance to impact, torque, and creep. Conductive and other thermoplastic materials and custom colors can be provided.
  • SOFT TOUCH are produced with a core material of fiberglass reinforced nylon for strength. A thermoplastic rubber material is molded over the knob surface to provide a soft and secure grip.
  • CUSTOM KNOBS MDI's unique tooling and production methods allow us to provide custom designs very inexpensively. Company logos and other embossed designs can be molded into our standard knobs for little or no additional cost. MDI can also provide design and engineering assistance when required.
