End the guesswork over the correct thread and ball sizes for your probe system! Our thread card has ten tapped holes, from M2 to 3/8-24, to check the thread size, and ten through holes, from 1.0 to 8.0 mm, to gage the ball size. A 40.0 mm engraved scale helps measure the stylus length. We make these from aircraft grade aluminum that is machined, de-burred, red anodized, and laser engraved. Protective slip cover included.
