OEP Four Prong Clamping Knobs are intended for heavy applications where a strong, sure grip is desired.

ALL of our knobs can be made with male studs, female inserts (through hole or blind top), or without an insert.
Available with free spin or Knob-Lok self-locking vibration resistant feature. Available with Blind Hole. Metric sizes available.
Minor tooling charges may apply if we previously have not made a part with a particular insert type/size/length.
