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. Often used to check gaps, alignment, and narrow slots, it tapers in thickness for checking a range of thicknesses.

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. The tapered-width gauge is designed for measuring hole and slot widths and diameters. The feeler gauge leaves check the thickness of slots, gaps, and alignment; each leaf is marked with thickness. Leaves are riveted together in a fan design that folds up for portability.
