Vermont Gage 111114800 Class Zz Plus Plug Gage 0.148 in

Product Description

The VERMONT GAGE 111114800 is a Class ZZ Plus plug gage used to verify hole diameters in precision machining and inspection work. Manufactured from tool steel with a 10 microfinish surface, it measures a nominal diameter of 0.148 inches to a tolerance of 0.0002 inches. At 2.0 inches in overall length, the gage is sized for comfortable single-hand use on the bench or at the machine. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming it meets the dimensional requirements of ASME B89.1. Machinists, quality technicians, and tool-room personnel rely on plug gages like this for fast, repeatable go-inspection of drilled, reamed, or bored holes.

This gage is suited for go inspection in production and tool-room environments where rapid attribute gauging of small-diameter holes is required. It is also used to calibrate and verify setting of micrometers, verniers, and other measuring devices. Applications span general metalworking, aerospace, automotive, and any industry holding tight hole-diameter tolerances in the 0.148-inch range.

Key Features

• Class ZZ Plus tolerance grade for reliable go-inspection performance
• 0.0002-inch tolerance for precise dimensional verification
• 10 microfinish surface finish reduces wear and protects the gaged bore
• Tool steel construction provides durability under repeated shop use
• Includes Certificate of Accuracy with NIST traceability, meeting ASME B89.1
• Suitable for setting micrometers, verniers, and other measuring devices

Compatibility

Designed for go inspection of holes with a nominal diameter of 0.148 inches. Also used as a setting standard for micrometers, verniers, and other hand measuring devices requiring a known reference diameter.

Installation Notes

Plug gages are handled and used by machinists and quality inspection personnel, not installed in a system. Store the gage in its case when not in use to prevent surface damage. Clean the gage and the bore to be checked before use to avoid false readings caused by chips or coolant. Handle with care to avoid drops that could alter the gage diameter or damage the microfinish.
