A certificate of calibration traceable to NIST states that this gauge has passed a test for accuracy.

Gauges are 12” long and have finished ends marked with thickness.

Use these feeler gauge assortments to check gaps, alignment, and narrow slots.

Keep spark plugs working efficiently. These feeler gauges slide between the electrodes to measure the gap.

To ensure accurate readings, these sets come with a certificate of calibration traceable to NIST that states they’ve passed a test for accuracy.

To keep the set complete, gauge leaves are riveted together in a fan design that folds up for portability.

A certificate of calibration traceable to NIST states that these sets have passed a test for accuracy.

Leaves have narrow ends to measure thickness where standard feeler gauges can’t fit.

Vital for dimensional quality control, these gauge blocks are often used for precision layout, machine setup, and producing close-tolerance dies and fixtures.

Use these Starrett gauge block sets for precision layout, machine setup, and producing close-tolerance dies and fixtures.

Use these Mitutoyo gauge block sets for precision layout, machine setup, and producing close-tolerance dies and fixtures.

These calipers come with a calibration certificate traceable to NIST that states they've passed a test for accuracy.

Protect sensitive electronics from damage while you take accurate measurements.

Carbide-tipped jaws provide greater wear resistance and longer life when measuring abrasive or very hard materials.

These calipers come with a calibration certificate traceable to NIST that states they've passed a test for accuracy.

These calipers have deep jaws for measuring large-diameter objects, such as pipes, poles, and logs.

Move the jaw along the ruler to take inside and outside measurements.

For measuring in and around machines, these calipers won’t be damaged by coolant.

Jaws move only when the thumb lock is depressed.

These calipers have a mechanism which allows you to make finer adjustments.

These calipers come with a calibration certificate traceable to NIST that states they've passed a test for accuracy.

The display, markings, and thumb wheel on these calipers are positioned for comfortable left-handed use.

These calipers comes with a calibration certificate traceable to NIST that states they've passed a test for accuracy.

These calipers come with a calibration certificate traceable to NIST that states they've passed a test for accuracy.

Designed with a rounded jaw for measuring the wall thickness of pipe, tubing, and other curved surfaces.

Measure center-to-center distances with the pointed jaws on these calipers, which are designed to self-center in holes.

Make accurate marks at precise measurements—these calipers have carbide-tipped jaws that press into workpieces for measuring and marking.

Adjust the left jaw up and down to measure stepped or offset planes.

The pointed jaws on this caliper can fit into smaller spaces than standard calipers jaws.
