The SPI 19-240-1 is a Class ZZ minus plug pin gage designed for precision bore and hole measurement in industrial and manufacturing environments. Built to a nominal diameter of 0.2400 inches with a minus tolerance of 0.0002 inches, this gage provides a reliable go or no-go reference for quality control inspections. The steel construction delivers the durability required for repeated use on the shop floor. Machinists, toolmakers, quality technicians, and inspection personnel use pin gages like this one to verify that drilled, reamed, or bored holes meet specified dimensional tolerances.
This gage is suited for dimensional inspection of precision holes in the 0.2400-inch range across a wide range of production and inspection applications. Class ZZ gages are commonly used in manufacturing facilities, job shops, and quality control labs where consistent, repeatable hole measurement is required. The minus designation means the gage is ground to the lower boundary of the tolerance band, making it appropriate for standard go-gage inspection protocols used in both light and heavy manufacturing settings.
Designed as an OEM-style replacement or direct-use plug pin gage for standard Class ZZ minus inspection applications involving holes at or near 0.2400 inches in diameter.
Pin gages are handled by quality technicians and machinists and require no permanent installation. Before use, clean the gage and the hole being measured to remove chips, oil, or debris that could affect readings. Store the gage in its case or protective sleeve when not in use to prevent surface damage that could compromise measurement accuracy. Follow your facility's established gage calibration and handling procedures to maintain traceability.
