    Wire, Width, and Thickness Feeler Gauge Sets

    Image of Product. Front orientation. Feeler Gauges. 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.

    Since each thickness is a different color, there’s no need to read the feeler gauge to tell your measurement. They are used to check gaps, alignment, and narrow slots. Gauges are nonmagnetic, nonmarring, noncorrosive, nonsparking, and resistant to oil.
