Vermont Gage 112204700 Class Zz Plug Pin Gage 4.70 Mm

Product Description

The VERMONT GAGE 112204700 is a Class ZZ Minus plug pin gage machined from steel and used to verify that a drilled, reamed, or bored hole does not exceed its maximum allowable size. At 4.70 mm in diameter with a tolerance of 0.00508 mm, this pin gage is suited for NoGo inspection work where tight dimensional control is required. The 10 microfinish surface coating ensures consistent, repeatable contact with the bore being checked. Each unit ships with a Certificate of Accuracy traceable to NIST standards, supporting quality documentation requirements in inspection and calibration environments. Machinists, quality technicians, and metrologists are the primary users of this tool.

This pin gage is used in machine shops, manufacturing facilities, and inspection labs where bore diameter verification is part of a standard quality control process. It is appropriate for use alongside set micrometers, verniers, and other precision measuring devices. The Class ZZ designation places it in the general-purpose inspection grade, making it a practical choice for production-floor NoGo checks rather than master or reference gage applications. The overall length is 2 inches, keeping it manageable for hand-use in tight inspection setups.

Key Features

• Class ZZ Minus designation for NoGo bore inspection
• 4.70 mm diameter with 0.00508 mm tolerance for precise dimensional verification
• 10 microfinish surface coating for consistent, repeatable contact
• Steel construction for durability in production and lab environments
• Includes Certificate of Accuracy with NIST Traceability for documentation compliance
• Compact 2-inch overall length for accessible handling

Compatibility

Designed for use in NoGo bore inspection applications and compatible with set micrometers, verniers, and other precision measuring devices where a 4.70 mm Class ZZ pin gage is specified.

Installation Notes

Pin gages are installed by hand and require no tools for use. Handle with clean, dry hands or lint-free gloves to prevent surface contamination that could affect accuracy. Store in a protective case away from moisture and temperature extremes to maintain calibration integrity. This type of gage should be used and maintained by qualified inspection or metrology personnel familiar with precision measurement practices.
