Vermont Gage 111209700 Class Zz Minus Plug Pin Gage 0.0970 in

Product Description

The VERMONT GAGE 111209700 is a Class ZZ Minus plug pin gage designed for NoGo inspection applications in dimensional quality control. Machined from steel with a 10 microfinish surface coating, this pin gage measures 0.0970 inches in diameter with an overall length of 2 inches and holds a tolerance of 0.0002 inches. It is used to verify that a hole or bore does not exceed its maximum allowable size. Each unit ships with a Certificate of Accuracy traceable to NIST, making it suitable for calibrated inspection environments in production, toolroom, and metrology lab settings.

This pin gage is applied in NoGo inspection routines where confirming upper-limit hole tolerance is critical. It is also used to set and verify micrometers, verniers, and other measuring devices requiring a known reference diameter. Typical users include quality control technicians, machinists, and metrologists working in manufacturing, aerospace, automotive, and general industrial environments where tight dimensional tolerances must be validated consistently.

Key Features

• Class ZZ Minus tolerance classification for NoGo inspection use
• 0.0970 inch diameter with 0.0002 inch tolerance for precise dimensional verification
• Steel construction with 10 microfinish surface coating for durability and accuracy
• 2 inch overall length for controlled handling in tight inspection setups
• Includes Certificate of Accuracy with NIST traceability for calibrated environments
• Compatible with micrometer, vernier, and general measuring device setup and verification

Compatibility

Designed for use in NoGo hole inspection routines and as a reference standard for setting micrometers, verniers, and other precision measuring devices requiring a traceable diameter reference.

Installation Notes

Pin gages are handled and used by quality control technicians and metrologists — no power source or mechanical installation is required. Keep the gage clean and free of oils, debris, and burrs before and after each use to preserve surface finish and accuracy. Store in a protective case away from temperature extremes to prevent thermal expansion errors. Reference ASME B89.1.5 or applicable metrology standards for Class ZZ gage usage and calibration interval guidance.
