Spi 19-826-7 Class Zz Minus Plug Pin Gage 0.826 in Dia

Product Description

The SPI 19-826-7 is a Class ZZ minus plug pin gage used to verify bore and hole diameters to a nominal size of 0.826 inches. Manufactured from steel, it holds a tolerance of 0.0002 inches, consistent with Class ZZ go/no-go gage standards used in production inspection environments. The minus designation indicates the gage is ground to the lower tolerance boundary, making it suitable for confirming minimum acceptable hole sizes. Machinists, quality control technicians, and tool room professionals use this gage as part of dimensional inspection routines on machined components, fixtures, and assemblies.

This gage is appropriate for use in machine shops, manufacturing facilities, and toolrooms where precise hole diameter verification is required. It fits into standard gage handle sets and is used in both incoming inspection and in-process quality checks. The 0.826-inch nominal diameter suits applications involving larger drilled, reamed, or bored features where Class ZZ accuracy is specified by print or process requirements.

Installation Notes

Plug pin gages are handled and used by machinists and quality technicians, not installed in a traditional sense. Store the gage in a protective case when not in use to prevent wear or damage to the ground surface. Handle with clean, dry hands or lint-free gloves to prevent corrosion from skin oils. Calibrate or certify the gage periodically per your facility quality management system requirements.
