Inspection and Measuring Fixturing
Use these components in coordinate measuring machine (CMM) applications to raise a workpiece and reliably position it on a fixture plate with 1/4"-20 holes. They are not for use in machining applications.

Hold-Down Clamps
Hold-Down Clamp
Hold-down clamps thread directly into a fixture plate, tower, or compatible component. Slide the clamp down its shaft and press into place against the workpiece for a light hold. They're also known as tension spring clamps. Wire clamps have a slimmer profile than standard, making them good for clamping small parts or minimizing contact area for additional visibility.
