Vermont Gage 111128200 Class Zz Plus Plug Gage 0.282 in

Product Description

The VERMONT GAGE 111128200 is a Class ZZ Plus plug gage used to perform go inspection of bored, drilled, and reamed holes. It measures hole diameters to a nominal size of 0.282 inches with a tolerance of 0.0002 inches, making it suitable for precision dimensional verification in manufacturing and machining environments. The gage body is machined from tool steel and carries a 10 microfinish surface finish. A Certificate of Accuracy with NIST traceability is included, supporting quality control documentation requirements. Licensed metrology technicians, machinists, and quality inspectors are the primary users.

This plug gage is intended for go inspection applications in production and inspection environments. It is used alongside set micrometers, verniers, and other measuring devices to verify that a bored or reamed hole falls within specified dimensional tolerances. The 0.282-inch diameter size is common in precision machined components where close-tolerance hole sizing must be confirmed before assembly. The gage is suited to both job-shop and production-line inspection workflows where ASME B89.1 compliance is required.

Key Features

• Class ZZ Plus tolerance rating per ASME B89.1 for go-plug inspection
• Nominal measurement diameter of 0.282 inches with 0.0002-inch tolerance
• 10 microfinish surface finish for accurate, repeatable contact with bore walls
• Tool steel construction for durability in production inspection use
• Includes Certificate of Accuracy with NIST traceability for QC documentation
• Overall length of 2.0 inches for standard hand-held use

Compatibility

Designed for go inspection of holes at 0.282-inch nominal diameter and for use with set micrometers, verniers, and other measuring devices. Conforms to ASME B89.1 standards for plain plug gages.

Installation Notes

Plug gages are handled and used by machinists, quality control inspectors, and metrology technicians. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel body. Never force the gage into a hole; apply only hand pressure to avoid damage to the gage or the workpiece bore. Store in the provided case or a protected location to preserve the precision-ground surface finish.
