Economy Feeler Gauge Sets

With Flat Round Leaves

With Offset Round Leaves

To keep the set complete, gauge leaves are riveted together in a fan design that folds up for portability. These sets are used to check gaps, alignment, and narrow slots. Each leaf is marked with thickness.

Stainless steel gauge sets are more corrosion resistant than steel.

Leaf-securing locks hold individual gauge leaves in place.

Feeler Gauge Rolls

Cut to your desired length. These gauge rolls let you check gaps, alignment, and narrow slots. Thickness is marked every 6 inches.

Steel gauge rolls are polished.

Brass gauge rolls have good corrosion resistance.

302/304 stainless steel gauge rolls are more corrosion resistant than brass and steel.

Color-Coded Feeler Gauges

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.
