Vermont Gage 111173800 Class Zz Plus Plug Gage 0.738 in

Product Description

The VERMONT GAGE 111173800 is a Class ZZ Plus plug gage designed for go inspection of bored, drilled, and reamed holes with a nominal diameter of 0.738 inches. Manufactured from tool steel with a 10 microinch surface finish, this gage delivers a tolerance of 0.0002 inches, making it suitable for precision inspection tasks in production and quality control environments. It ships with a Certificate of Accuracy that carries NIST traceability, meeting the documentation requirements of calibrated inspection tooling. Licensed metrologists, quality technicians, and machinist trades use this type of gage to verify that a feature falls within its acceptable dimensional range before the part advances to the next stage of manufacture.

This plug gage is applied wherever a go-member check is needed on a hole or bore measuring 0.738 inches in diameter. Typical settings include machine shops, fabrication facilities, and inspection labs performing first-article, in-process, or final acceptance checks. It is also used to calibrate or verify the accuracy of set micrometers, verniers, and other measuring devices, as noted in the manufacturer application data. The 2.0-inch overall length provides adequate hand clearance for use in shallow to moderate-depth features.

Key Features

• Class ZZ Plus tolerance of 0.0002 inches for reliable go-member inspection
• 0.738-inch nominal measurement diameter in decimal inch format
• 10 microinch surface finish for consistent gage-to-feature contact
• Tool steel construction for hardness and wear resistance
• Conforms to ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST traceability

Compatibility

Designed for go inspection of holes and bored features with a 0.738-inch nominal diameter, and suitable for use as a setting standard with set micrometers, verniers, and other precision measuring devices per manufacturer application data.

Installation Notes

Plug gages are handled and applied by quality technicians and machinist trades; no permanent installation is required. Store the gage in its case when not in use and keep it clean and lightly oiled to prevent corrosion of the tool steel. Do not force the gage member into a feature that offers significant resistance, as this can damage both the gage and the workpiece. Periodic recalibration against a traceable standard is recommended to maintain measurement integrity over time.
