The Williams SNPGS-1 is a master feeler gauge set.
Note that the source carries nothing else. Verify the blade count, thickness range, and length against Williams' specification before publishing — those are the specifications the set is chosen on.
A feeler gauge measures a gap by filling it, which is a beautifully direct method and one that depends entirely on technique.
The blade is inserted into the clearance and the operator reads the fit by feel. The correct feel is a slight drag — the blade moves with light resistance. A blade that slides freely means the gap is larger than the blade. A blade that will not enter means it is smaller. Between those, the drag is the measurement, and it is a genuinely learnable skill rather than a knack.
The mistake is force. Pushing a blade into a gap it does not fit bends the blade permanently, and a bent feeler gauge reads wrong forever afterward without looking any different.
Master indicates a comprehensive set — enough blades to build up combinations for gaps between the individual thicknesses, which is how a feeler set covers a continuous range with discrete blades.
Keep them clean and dry. Feeler blades are thin steel and they rust, and a rusted blade is thicker than it says.
Applications include valve clearances, bearing gaps, and machine setup.
