Spi 19-928-1 Class Zz Minus Plug Pin Gage 0.928 in

Product Description

The SPI 19-928-1 is a Class ZZ minus plug pin gage designed to verify hole diameters and bore sizes with a nominal measurement diameter of 0.928 inches. Built from steel, this pin gage is used as a go/no-go inspection tool to confirm that a machined or bored feature falls within acceptable dimensional tolerances. The minus tolerance configuration means the gage is manufactured to the lower limit of the tolerance band, with a tolerance of 0.0002 inches. Machinists, quality control technicians, and toolroom personnel use Class ZZ gages for general-purpose inspection of production parts.

This plug pin gage is suited for dimensional inspection tasks in machine shops, manufacturing facilities, and toolrooms. It is appropriate for verifying hole sizes in metal components where general-purpose gage accuracy is required. Class ZZ is a widely accepted standard for production-grade inspection gages used on the shop floor. The 19-928-1 is sold individually and is appropriate for use with standard gage handle sets compatible with 0.928-inch diameter pin members.

Installation Notes

Pin gages should be handled and stored carefully to prevent damage to the precision ground surfaces. Clean the gage and the bore being inspected before use to ensure accurate readings. Do not force the gage into a hole; light hand pressure is sufficient for proper inspection technique. Gages should be periodically calibrated and inspected for wear in accordance with your facility quality management procedures.
