Plastic Clearance Gauges

Squish these tiny plastic strips between two components to measure the clearance between them. Once compressed, match the widest part of the flattened strip to the markings on the paper gauge. Each marking on the gauge corresponds to a different clearance measurement.

Feeler Gauges

Starrett Tapered-Thickness Feeler
Gauges with Calibration Certificate

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

Starrett Tapered-Thickness Feeler Gauges

Check a range of thicknesses with a single tapered gauge.

Tapered-Thickness Feeler Gauges

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

Ready-to-Use Feeler Gauges

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

Feeler Gauge Assortments

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

Feeler Gauge Rolls

Cut to your desired length.

Color-Coded Feeler Gauges

Since each thickness is a different color, there’s no need to read the feeler gauge to tell your measurement.

Feeler Gauge Holders

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

Feeler Gauge Sets

Starrett Feeler Gauge Sets for Tight
Spots with Calibration Certificate

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

Starrett Feeler Gauge Sets for Tight Spots

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

Economy Feeler Gauge Sets for Tight Spots

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

Starrett Feeler Gauge Sets

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.

Starrett Feeler Gauge Sets with Calibration Certificate

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

Economy Feeler Gauge Sets

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

Color-Coded Feeler Gauge Sets

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

Combination Wire, Width, and
Thickness Feeler Gauge Sets

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

Tapered-Width Feeler Gauge Sets

Width markings on the leaves let you for check diameters and widths.
