Precision Feeler Gauge 19821

This 25-blade feeler gauge set is built from high-carbon steel for mechanics and electricians who need accurate gap measurements during assembly, adjustment or maintenance work. The assortment covers a wide range of clearances found in automotive, industrial and electrical applications.

Thickness range .0015 in to .035 in

The thinnest blade measures .0015 inch while the thickest reaches .035 inch, giving a practical span for most valve, contact and spark-plug gaps. Blades outside this interval require a separate gauge set.

25 blades cover common service gaps

The set handles clearances from .038 mm to .889 mm in graduated steps, suiting routine ignition, valve-train and relay adjustments. Extremely fine shims below .038 mm or heavy shims above .889 mm are not included.
