Vermont Gage 112206700 Class Zz Minus Plug Pin Gage 6.70 Mm

Product Description

The VERMONT GAGE 112206700 is a Class ZZ Minus plug pin gage machined from steel and used to perform NoGo inspection on bored, drilled, or reamed holes. Measuring 6.70 mm in diameter with a tolerance of 0.00508 mm, this pin gage gives metrology technicians and quality inspectors a reliable go/no-go reference for verifying hole sizes to tight dimensional standards. The 10 microfinish surface coating reduces wear and maintains accuracy over repeated use. Each unit ships with a Certificate of Accuracy backed by NIST traceability, making it suitable for use in calibrated inspection environments.

This pin gage is used in dimensional inspection applications across manufacturing, machining, and quality control settings. It is appropriate for both production floor checks and tool room inspection. Typical applications include verifying bore diameters on machined components and setting or checking micrometers, verniers, and other measuring devices. The Class ZZ Minus designation means the gage is ground to the minus side of the tolerance, making it correct for NoGo inspection use where the pin must not pass through an acceptable hole.

Key Features

• 6.70 mm measurement diameter with 0.00508 mm tolerance for precise NoGo inspection
• Class ZZ Minus grind - correct tolerance direction for NoGo gage applications
• Steel construction with 10 microfinish surface for durability and dimensional stability
• Certificate of Accuracy included with NIST traceability for calibrated inspection environments
• Suitable for setting micrometers, verniers, and other measuring devices
• Overall length of 2 inches for easy handling in standard gage holders

Compatibility

Designed for use with standard pin gage handles and gage sets in dimensional inspection of 6.70 mm nominal bore diameters. Also suitable for setting and verifying micrometers, verniers, and comparable measuring instruments.

Installation Notes

Pin gages are handled by metrology technicians and quality inspectors and require no power-down procedure. Store in a clean, dry environment away from temperature extremes to prevent thermal expansion errors. Handle with clean cotton gloves or a lint-free cloth to avoid surface contamination that can affect measurement accuracy. Do not force the gage through a hole - improper use can damage the gage surface and invalidate NIST-traceable calibration.
