Spi 19-116-3 Class Zz Minus Plug Pin Gage 0.116 in

Product Description

The SPI 19-116-3 is a Class ZZ minus plug pin gage machined from steel and used to verify bore and hole diameters to a high degree of accuracy. The gage measures a nominal diameter of 0.116 inches and holds a minus tolerance of 0.0002 inches, placing it within Class ZZ specifications for go/no-go inspection work. Pin gages at this tolerance class are standard tools in quality control environments, machine shops, and precision assembly operations. Machinists and QC technicians use minus plug gages to confirm that a hole is at or above the minimum acceptable diameter before a part advances to the next production stage.

This gage is suited for inspection of drilled, reamed, or punched holes in manufacturing and fabrication settings. It fits into standard pin gage handle sets or can be used with gage blocks and fixtures. The 0.116-inch diameter range is common in light-duty mechanical assemblies, precision sheet metal work, and component fitment verification. Shops that maintain a complete set of pin gages for go/no-go inspection will find this gage integrates directly into existing workflows.

Compatibility

Designed as an OEM-style replacement or supplemental gage for use with standard pin gage handle sets accepting 0.116-inch diameter pin gages.

Installation Notes

Pin gages are installed and used by machinists, quality control technicians, and tooling specialists. Before use, clean the gage and the bore being inspected to remove chips, oils, or debris that could affect measurement accuracy. Insert the gage with light hand pressure only — never force a pin gage, as this can damage the gage or the workpiece. Store pin gages in a protective case away from other tooling to prevent surface damage that would compromise dimensional accuracy.
