Vermont Gage 111312150 Class Zz Plus Plug Gage 0.1215 in

Product Description

The VERMONT GAGE 111312150 is a Class ZZ Plus plug gage designed for go inspection of bored, drilled, and reamed holes at a nominal diameter of 0.1215 inches. Manufactured from tool steel with a 10 microfinish surface, it delivers a tolerance of 0.0002 inches, making it suitable for precision dimensional verification in machine shops, quality labs, and production-floor inspection stations. The gage ships with a Certificate of Accuracy traceable to NIST and conforms to ASME B89.1. Machinists, quality technicians, and metrology professionals use this type of gage to confirm that a feature meets minimum size requirements before assembly or further machining.

This plug gage is used in applications requiring precision go inspection at the 0.1215-inch diameter range. Typical uses include verifying hole size on machined components, setting micrometers, and calibrating verniers and other measuring devices. It is well-suited for both production inspection environments and tool-room calibration work where NIST-traceable documentation is required for quality system compliance.

Key Features

• Class ZZ Plus tolerance of 0.0002 inches for precise go inspection
• 10 microfinish surface for smooth, consistent gaging contact
• Tool steel construction for durability in production environments
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 standard
• Overall length of 2.0 inches for easy handling in standard gage handles

Compatibility

Designed for go inspection of holes with a nominal diameter of 0.1215 inches. Also suitable for setting micrometers, verniers, and other measuring devices requiring a certified reference at this diameter.

Installation Notes

Plug gages are handled and used by quality technicians and machinists; no power source or mechanical installation is required. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel surface. Do not force the gage into an undersized hole, as this can damage the gage member and compromise calibration. Store in the provided case or a clean, dry location away from abrasive materials.
