Vermont Gage 112209220 Class Zz Minus Plug Pin Gage 9.22mm

Product Description

The VERMONT GAGE 112209220 is a Class ZZ Minus plug pin gage designed for precision dimensional inspection. Machined from steel with a 10 microfinish surface coating, this pin gage checks bore and hole diameters to a tolerance of 0.00508 mm. It measures 9.22 mm in diameter and has an overall length of 2 inches. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming the gage meets Class ZZ Minus tolerance standards. Machinists, quality technicians, and metrology lab personnel use these gages during incoming inspection, in-process checks, and final part verification.

This plug pin gage is used in NoGo inspection applications to verify that a hole or bore has not been machined oversize. It is also suited for setting micrometers, verniers, and other measuring devices to a known reference dimension. Typical environments include machine shops, toolrooms, and quality control labs handling precision-machined components. The 9.22 mm size targets metric-dimensioned workpieces common in automotive, aerospace, and general manufacturing work.

Key Features

• Class ZZ Minus tolerance of 0.00508 mm for reliable NoGo inspection
• Steel construction with 10 microfinish surface for consistent contact and wear resistance
• 2-inch overall length for easy handling in standard gage blocks and pin holders
• Includes Certificate of Accuracy with NIST traceability for calibration documentation
• Suitable for setting micrometers, verniers, and other precision measuring devices

Compatibility

Designed for use as a NoGo inspection gage for holes and bores dimensioned at 9.22 mm, and as a reference standard for setting micrometers, verniers, and similar measuring instruments.

Installation Notes

Pin gages are handled and stored by quality technicians and metrologists, not installed in mechanical systems. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the steel shank. Do not force the pin into a bore; Class ZZ Minus gages should pass freely through an in-tolerance NoGo hole without pressure. Store in the original case or a protective sleeve to maintain surface finish and dimensional integrity.
