The case exterior is labeled "M1 Minus 190 Piece," with the operator label "FMI-1114" and a "Verify Before Use" sticker applied. Pin gages of this type are used for hole size verification, slot width inspection, Go/No-Go gaging, and inter-hole distance measurement in precision machining, toolroom, and quality control environments. The range of 0.061 to 0.250 inch covers a high-demand span for common drilled and reamed hole sizes encountered in production and inspection work.
