Vermont Gage 111300650 Class Zz Plus Plug Gage 0.0065 in

Product Description

The VERMONT GAGE 111300650 is a Class ZZ Plus plug gage designed to measure bores and holes at a nominal diameter of 0.0065 inches with a tolerance of 0.0002 inches. Made from tool steel, it delivers consistent, repeatable results in precision inspection environments. The gage carries a 10 microfinish surface and comes with a Certificate of Accuracy with NIST traceability, making it suitable for documented quality-control workflows. It has an overall length of 2 inches. Machinists, quality technicians, and metrology professionals use this tool where tight-tolerance hole verification is required.

This plug gage is intended for go inspection applications, confirming that a hole or bore meets its minimum acceptable size. It is also used to set and verify micrometers, verniers, and other precision measuring devices in shop or lab environments. The 0.0065-inch diameter makes this gage applicable to very small-bore inspection tasks common in precision machining, tooling, and instrument manufacturing. Residential or light-trade use is uncommon; this is a professional-grade metrology tool suited to controlled manufacturing and inspection settings.

Key Features

• Class ZZ Plus accuracy grade for small-bore go inspection
• 0.0065-inch nominal diameter with 0.0002-inch tolerance
• 10 microfinish surface for consistent gauge contact
• Tool steel construction for durability and dimensional stability
• Includes Certificate of Accuracy with NIST traceability for documented inspection records
• Conforms to ASME B89.1 standards

Compatibility

Designed for go inspection of holes and bores at 0.0065 inches nominal diameter, and for setting micrometers, verniers, and other precision measuring devices per ASME B89.1.

Installation Notes

Handle plug gages with clean, dry hands or lint-free gloves to prevent corrosion from skin oils. Store in a protective case away from temperature extremes to maintain dimensional accuracy. When using to set measuring instruments, allow both the gage and the instrument to stabilize at the same ambient temperature before measurement. Do not force the gage into an undersized bore, as this will damage the gage surface and invalidate the tolerance.
