Vermont Gage 111101500 Class Zz Plus Plug Gage 0.015 in

Product Description

The VERMONT GAGE 111101500 is a Class ZZ Plus plug gage designed for precise go-inspection of small-diameter bores and holes. Measuring 0.015 inches in diameter, this gage holds a tolerance of 0.0002 inches and features a 10 microfinish surface on the gage member. Constructed from tool steel, it delivers the hardness and dimensional stability required for repeated use in production and inspection environments. Each unit ships with a Certificate of Accuracy traceable to NIST, making it suitable for documented quality-control programs. Overall length is 2.0 inches. Licensed metrologists, quality technicians, and tool-room inspectors are the primary users of this instrument.

This plug gage is used in shop-floor and laboratory inspection settings where small-bore feature acceptance must be verified against tight dimensional tolerances. Typical applications include verifying bore diameters on precision machined components and calibrating or setting micrometers, verniers, and other measuring devices. The Class ZZ Plus designation indicates a tolerance grade appropriate for inspection-grade go gaging per ASME B89.1 standards. It is well suited for aerospace, automotive, and general precision machining inspection workflows.

Key Features

• 0.015-inch nominal diameter with 0.0002-inch tolerance for tight go-inspection accuracy
• 10 microfinish gage surface minimizes wear on precision bores during inspection
• Tool steel construction provides hardness and long service life in production use
• Meets ASME B89.1 standards for plug gage dimensional requirements
• Includes Certificate of Accuracy with NIST traceability for quality documentation
• Compatible with use as a setting standard for micrometers, verniers, and similar measuring devices

Compatibility

Designed for go inspection of bores at 0.015-inch nominal diameter, and for use as a setting reference with micrometers, verniers, and other measuring devices as stated in the manufacturer application data.

Installation Notes

Plug gages are handled and used by quality technicians and tool-room personnel, not installed in mechanical systems. Store the gage in its protective case when not in use to prevent surface damage. Clean the gage member with a lint-free cloth before each use to remove oils and debris that could affect measurement accuracy. Avoid dropping or contacting the gage against hard surfaces, as impact can alter the geometry of the precision-ground member.
