    Secure a workpiece from the inside diameter, leaving the outside clear for machining. Machine these clamps to match the precise size and contours of your workpiece ID. Mount the clamp to your fixture with the included screws and place your workpiece over it. Turn the socket head cap screw to expand the clamp.
    Side Actuation—Side-actuated clamps tighten from the side of the clamp, gripping parts without a through hole in the top.

    Unlike the smooth and flat edges of standard fixture clamps, these clamps have ridges that bite into parts, making them good for gripping castings and rough-cut stock. They hold workpieces securely from the side with minimal contact, leaving more of the surface free for machining. Thread the clamp into a tapped hole and give the center screw a half turn for quick clamping.
