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.

Fixture Plates
Fixture Plate
Fixture plates have a grid of 1/4"-20 threaded holes spaced 1/2" apart for attaching components. Alpha-numeric markings around the edges of the plates make it easier to identify holes and repeat tasks. Use aluminum plates with CMMs and optical comparators. Use acrylic plates on vision systems. They are transparent to provide your system with a view of the workpiece.
