Spi 22-191-1 Class Zz Plug Gage Set 200 Pc

Product Description

The SPI 22-191-1 is a Class ZZ plug gage set covering a diameter range of 10.000 mm to 13.98 mm with a plus 0.005 mm tolerance. The set includes 200 pin gages and is designed for fast, accurate inspection of hole sizes, slot widths, and distance calculations between holes. Each set ships with a Certificate of Accuracy that is NIST traceable and includes a pin gage holder. This set is well suited for quality control technicians, machinists, and inspection personnel who require reliable go-gage verification on production floors or in metrology labs.

The 22-191-1 is used in machining and manufacturing environments where precise hole inspection is required. The 10.000 mm to 13.98 mm range covers a broad set of common bore and slot dimensions encountered in general metalworking and precision fabrication. The Class ZZ tolerance classification makes this set appropriate for inspection-grade go gaging applications. It is commonly used at incoming inspection stations, on the shop floor, and in quality assurance departments.

Compatibility

Designed for use as inspection-grade plug gages in machining, fabrication, and quality control applications requiring diameter verification in the 10.000 mm to 13.98 mm range.

Installation Notes

Pin gages should be handled by trained inspection or metrology personnel. Clean gage pins and bores before use to prevent contamination that can affect measurement accuracy. Store pins in the included holder when not in use to prevent damage to gage surfaces. Do not force pins into bores; if resistance is encountered, verify the correct pin size is being used.
