A machine tool clamp includes an elongated clamping member with its mid-section anchored at an adjustably spaced distance above a base plate. The front end of the clamping member is adapted to clamp a work piece to a machine tool work platform. The rear end or heel of the clamping member bears pivotally on the base plate in such a manner that the adjustable anchor of the mid-section is a movable fulcrum. A height adjustable mechanism with a large mechanical advantage is positioned in the heel of the clamping member to lever the clamping member about the adjustable fulcrum to clamp the front end on a work piece. The height adjustable mechanism can be a screw, eccentric cammed lever, hydraulic or pneumatic cylinder, or other suitable mechanism.
