Precision 77120 Feeler Gauge Set

The Precision 77120 feeler gauge set contains twelve stainless-steel blades, each measuring 0.001 inch thick. It is intended for mechanics and engineers who need to measure very small clearances during assembly or maintenance work. The long 12-inch blade length allows access to deep or recessed gaps.

Measurement Limits and Standards

Each blade carries a tolerance of plus or minus ten percent on the stated thickness. The set conforms to ASTM A-666 chemistry requirements for stainless steel. California Proposition 65 warnings apply because the product contains a chemical known to cause reproductive harm. The blades are non-magnetic and marked in inch graduations only.

Installation and Common Issues

Blades are removed from the holder and inserted into the gap until a slight drag is felt. A frequent error is forcing a blade, which bends the thin 0.001-inch material and ruins its accuracy. Another common mistake is stacking multiple blades without verifying the combined thickness, which compounds the individual tolerances. Always store the set dry to prevent surface corrosion on the unfinished steel.
