Vermont Gage 112207660 Class Zz Minus Plug Pin Gage 7.66 Mm

Product Description

The VERMONT GAGE 112207660 is a Class ZZ minus plug pin gage designed to perform NoGo inspection of bored, drilled, and reamed holes. It measures a nominal diameter of 7.66 mm with a tolerance of 0.00508 mm, confirming that a hole has not exceeded its maximum allowable size. The gage is machined from steel and finished to a 10 microfinish surface, producing a smooth, consistent contact surface that reduces measurement error. Overall length is 2 inches. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting quality documentation requirements in ISO-compliant and regulated manufacturing environments. Machinists, quality technicians, and toolroom personnel use this gage in production and incoming inspection workflows.

This pin gage is suited for NoGo inspection applications across general machining, toolroom, and quality control settings. It is also used to set and verify micrometers, verniers, and other measuring devices where a known reference diameter is required. The Class ZZ tolerance designation places it in the working-gage category, appropriate for production floor inspection rather than master or reference gage applications. It is compatible with standard gage handle systems and interchangeable with other pin gages of the same shank diameter in modular gage sets.

Key Features

• Class ZZ minus tolerance designation for NoGo hole inspection
• 7.66 mm nominal measurement diameter with 0.00508 mm tolerance
• 10 microfinish surface coating for consistent, low-error contact
• Steel construction for durability in production and toolroom use
• Includes Certificate of Accuracy with NIST traceability for quality documentation
• 2 inch overall length compatible with standard modular gage handle systems

Compatibility

Designed for use in NoGo hole inspection, micrometer setting, and verification of verniers and other measuring devices. Fits standard modular plug gage handle systems accepting the corresponding shank diameter.

Installation Notes

Plug pin gages are handled and used by quality technicians and machinists without special tooling. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the steel surface. Do not force the gage into a hole; controlled hand pressure is sufficient for inspection. Store in the provided case or a clean dry location away from abrasive materials to preserve the microfinish surface.
