These calipers come with a calibration certificate traceable to NIST that states they've passed a test for accuracy. Carbide-tipped jaws provide greater wear resistance and longer life when measuring abrasive or very hard materials. Built-in backlash control stabilizes the needle for accurate readings.

Depth base attachment (sold separately) stabilizes your caliper when taking depth measurements.

These attachments clamp onto the end of Mitutoyo electronic, dial, and vernier calipers to stabilize them when taking depth measurements.

Expand electronic, dial, and vernier calipers to measure larger items. Extenders have two pins that project 1/2" when installed and act as jaws for the extension. 1 1/2" extended projection pins are sold separately.

Use optional center-to-center gauge pins to determine the center-to-center distance between holes. The pins taper to a sharp point.

Attach to electronic, dial, and vernier calipers for the added versatility of measuring slots, inside pockets, shoulders, and holes.

Set includes a dial caliper, a micrometer, a ruler, and a case. The micrometer has a friction thimble with a constant-force mechanism, so that once the spindle contacts the surface of the measured object, it will stop tightening. This ensures repeatable measurements and prevents over-tightening. Once the spindle stops tightening, the thimble will continue turning with resistance.
