Our deepest jaws for measuring extra-large, round objects, such as shafts, poles, and logs. Don’t let the size of these calipers deter you—their aluminum body makes them light enough to comfortably carry around.

Move the jaws exactly where you need them. The fine-adjustment wheel opens and closes the jaws in small, precise increments for extra control while measuring.

These classic calipers use a sliding vernier scale. Just add the measurement from the main scale to the measurement on the vernier scale to get accurate readings as small as 0.001". Made completely out of metal, they won't break when dropped or short-circuit when wet. They're battery-free, so they're always ready to use.

Prevent the jaws from creeping forward or backward as you measure. They move only when you press a button, then lock in place when you let go. The button falls naturally under your thumb, so you can operate these calipers comfortably with one hand.

No longer than a pencil for quick measurements on the go. Made entirely of metal, these calipers won't break if dropped or short-circuit if rinsed or rained on.

Prevent static from damaging sensitive electronics as you measure them. The fiberglass body drains static away from your workpiece so you don't pass along harmful charges.

To calculate your final measurement, simply add the value on the dial to the number on the main scale. These calipers are battery-free, so they’re always ready to use. However, the glass dial and internal components can break if accidentally dropped.

Your traditional calipers, combining precision and durability. This classic design uses a sliding vernier scale. Just add the measurement from the main scale to the measurement on the vernier scale to get accurate readings as small as 0.001". Made completely out of metal, these calipers won't break when dropped or short-circuit when wet. They're battery-free, so they're always ready to use.

Set includes a dial caliper, a micrometer, a ruler, and a case. The micrometer has a ratchet thimble with a constant-force mechanism, which stops the spindle from tightening once it contacts the surface of the measured object. This ensures repeatable measurements and prevents over-tightening. When the spindle stops tightening, the thimble will continue turning with a clicking sound. A speeder knob reduces the time it takes to open and close the micrometer.

This set comes with calibration certificates traceable to NIST that state each tool has passed a test for accuracy. It includes a dial caliper, a micrometer, a ruler, and a case.

Sets include 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.
