Air-Powered Hold-Down Fixture Clamps
Adjust the air pressure to quickly and consistently clamp and release parts. The arm on these clamps rotates 90° into position over the workpiece and then moves straight down to clamp. Disengage to rotate the arm out of the way and load or unload parts. Also known as swing clamps, they are used with a solid state switch or Reed function switch with M8 male 3-pin connectors. Connect the clamp's ports to a control valve and an air line. Clamps mount with screws.
Clamps with rubber-tipped holding screw are nonmarring. Tip is removable.

Threaded Air-Powered Hold-Down Fixture Clamps
Screw these clamps directly into a tapped hole and use air pressure to quickly and consistently clamp and release parts. The arm rotates 90° into position over the workpiece and then moves straight down to clamp. Disengage to rotate the arm out of the way and load or unload parts. Also known as swing clamps, they're used with a solid state switch or Reed function switch with M8 male 3-pin connectors. Connect the clamp's ports to a control valve and an air line. To hold clamps in an untapped hole, use a mounting block (sold separately).
Clamps with rubber-tipped holding screw are nonmarring. Tip is removable.

Hold-Down Fixture Clamps
Tighten the spring-loaded socket head cap screw on these clamps to hold your workpiece from above. Also known as swing clamps, you can rotate the hook out of the way when the screw is loose. Install these clamps in a drilled hole for maximum rigidity.
Add mounting blocks to rotate the clamp’s hook consistently—these blocks have a stop every 90°. They’re also useful if you don’t have an easy mounting location for the fixture clamp.
