    Top Actuation

    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.
    Top Actuation—Top-actuated clamps tighten from the top of the clamp, so workpieces need a through hole.

    Blunt Edge

    Install these clamps into a slot in your fixture to grip at the bottom of workpiece edges, giving the cutting tool maximum access to your workpiece. Thread the clamp into a tapped hole and give the center screw a half turn for quick clamping.
    Blunt Edge—Clamps with a blunt edge are less likely to mar your workpiece.
    Brass Head—Clamps with brass heads are nonmarring when used with steel and aluminum workpieces.
