Vermont Gage 112105800 Class Zz Plus Plug Gage 5.8mm

Product Description

The VERMONT GAGE 112105800 is a Class ZZ Plus plug gage designed for precise go-type inspection of bored, drilled, and reamed holes. Manufactured from tool steel with a 10 microfinish surface coating, this gage checks whether a hole falls within acceptable dimensional limits. The nominal diameter is 5.8 millimeters with a tolerance of 0.005 mm, making it suitable for applications requiring close dimensional control. At 2.0 inches in overall length, the handle is compact enough for bench or in-process use. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting quality documentation requirements. Licensed metrology technicians, machinists, and quality control inspectors are the primary users.

This plug gage is used in manufacturing and inspection environments where hole diameter verification is required before assembly or further machining. Typical applications include go inspection of precision-bored components, setting and verifying micrometers, verniers, and other measuring devices. It is well-suited for both production floor use and calibration lab environments where ASME B89.1 compliance is required. The 5.8 mm nominal size fits common metric hole specifications found in light mechanical assemblies and precision components.

Key Features

• Class ZZ Plus tolerance of 0.005 mm for close-tolerance go inspection
• Tool steel construction for durability and wear resistance
• 10 microfinish surface coating for smooth, consistent contact
• NIST-traceable Certificate of Accuracy included with each gage
• Meets ASME B89.1 dimensional standards
• Compact 2.0-inch overall length for easy handling at the bench or machine

Compatibility

Suitable for go inspection of 5.8 mm diameter holes and for setting micrometers, verniers, and other measuring devices requiring a certified reference standard.

Installation Notes

Plug gages are handled and used by quality technicians, machinists, and metrologists - no power tools or electrical shutoff procedures apply. 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 a hole; if resistance is felt, the hole is undersize and should be returned for rework. Store in a protective case away from temperature extremes to maintain dimensional stability.
