    Quarter-Turn Quick-Change Fixture Clamps

    Image of System. Side1 orientation. Exploded view. Contains Annotated. Fixture Clamps. Quarter-Turn Quick-Change Fixture Clamps.
    Install these clamps into fixture plates, machine subplates, and tombstones to quickly swap components in or out of your machining setup. They lock or unlock with the turn of a knob. Since they locate while they clamp, you can accurately position components with repeatability of ±0.1".
    For accurate positioning, use at least two sets of clamps and cam receptacles. Install receptacles into a base plate and clamps into a fixture plate. Line up the two plates, insert the clamps into the receptacles, then turn the knobs to secure your fixture in place. If you need more holding capacity, use additional clamps and receptacles.

    Fastener Mount—Fastener-mount receptacles have three recessed holes on the face so you can secure them to your base plate with the included screws.
    Thread In—Thread-in receptacles have a threaded body for installation in a tapped hole. You hold them in place with the included nut, so they’re good for thin base plates.
