Check gaps, alignment, and narrow slots with these feeler gauge sets that include leaves in a variety of thicknesses riveted together in a fan design.

With leaves that are color coded based on thickness, you can read your measurements at a glance.

To measure thickness in areas where standard feeler gauges don’t fit, these sets have leaves with narrow ends.

These sets combine a wire gauge, a tapered-width feeler gauge, and a set of feeler gauges for tight spots in one tool.

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

Check a range of thicknesses with a single tapered gauge.

Replace an entire feeler gauge set with one of these tapered gauges that lets you check a range of thicknesses.

Keep your feeler gauge in position with the cam-lock clamps on these holders.

Confirm slots, holes, and mating surfaces on parts are properly sized. Narrow at one end, these feeler gauges measure a range of sizes.
