Vermont Gage 112415350 Class Zz Minus Plug Pin Gage 15.35mm

Product Description

The VERMONT GAGE 112415350 is a Class ZZ Minus plug pin gage manufactured from steel and used to perform NoGo inspection of machined bores and holes. The gage measures 15.35 mm in diameter and holds a tolerance of 0.00508 mm, making it suitable for precision dimensional inspection in production and quality-control environments. Overall length is 2 inches. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting documentation requirements for ISO and AS9100 quality systems. Metrology technicians and quality inspectors rely on this gage to verify that a hole does not exceed its maximum material condition limit.

This plug pin gage is used in dimensional inspection applications including NoGo bore verification, calibration of micrometers, verniers, and other measuring devices. It is suited to both job-shop and production floor environments where consistent, traceable measurement of 15.35 mm features is required. The Class ZZ tolerance classification designates this gage for general inspection use, making it a practical choice for incoming inspection, in-process checks, and final quality audits across metalworking, aerospace, and precision manufacturing operations.

Key Features

• 15.35 mm measurement diameter with 0.00508 mm tolerance for precise bore verification
• Steel construction for durability and dimensional stability in shop environments
• 10 micro coating and finish for surface protection and measurement consistency
• Includes Certificate of Accuracy with NIST traceability to satisfy quality system documentation requirements
• Compact 2-inch overall length for easy handling and storage

Compatibility

Designed for use as a NoGo plug pin gage in inspection of machined bores measuring 15.35 mm, and for use with micrometers, verniers, and other dimensional measuring devices requiring a traceable reference standard.

Installation Notes

This gage is handled by metrology technicians and quality inspectors rather than installed in a mechanical system. Keep the gage clean and lightly oiled when not in use to prevent corrosion and maintain dimensional accuracy. Do not drop or impact the gage, as steel pin gages are susceptible to dimensional changes from physical shock. Store in a protective case away from temperature extremes to preserve NIST-traceable accuracy.
