Vermont Gage 112100860 Class Zz Plus Plug Gage 0.86 Mm

Product Description

The VERMONT GAGE 112100860 is a Class ZZ Plus plug gage machined from tool steel for dimensional go inspection of small bores and holes. It measures 0.86 mm in diameter with a tolerance of 0.005 mm (0.00508 mm nominal), making it suitable for tight-tolerance verification work. The gage features a 10 microfinish surface, which minimizes wear on the workpiece during repeated inspection passes. A Certificate of Accuracy with NIST traceability is included, supporting quality documentation requirements in regulated production and metrology environments. Licensed metrologists, machinists, and quality technicians use this tool as part of go/no-go inspection routines and for setting micrometers, verniers, and other precision measuring devices.

This plug gage is designed for precision go inspection of small-diameter holes in manufacturing and quality control settings. Typical applications include verifying bore dimensions on machined components, calibrating measuring instruments, and confirming feature acceptance in close-tolerance production runs. The 0.86 mm diameter makes it appropriate for micro-bore inspection tasks where standard-sized gages cannot reach. The overall length of 2.0000 inches allows comfortable handling during bench or in-line inspection work. It conforms to ASME B89.1 standards, aligning with widely used dimensional metrology requirements in industrial facilities.

Key Features

• Class ZZ Plus tolerance grade with 0.005 mm (0.00508 mm) tolerance for precision go inspection
• 0.86 mm diameter for micro-bore and small-feature verification
• 10 microfinish surface finish reduces workpiece contact wear during inspection
• Tool steel construction for durability and dimensional stability under repeated use
• Certificate of Accuracy with NIST traceability included for quality system documentation
• Conforms to ASME B89.1 dimensional metrology standards

Compatibility

Suitable for use as a go inspection gage and for setting micrometers, verniers, and other precision measuring devices where a 0.86 mm reference diameter is required.

Installation Notes

Plug gages of this class are handled and used by trained metrologists, machinists, and quality control technicians. Store the gage in its protective case when not in use to prevent surface contamination or dimensional damage. Clean both the gage and the workpiece bore before inspection to avoid false readings caused by debris or cutting fluid residue. Do not force the gage into an undersized bore, as this can damage the gage surface and compromise NIST-traceable accuracy.
