Vermont Gage 112119340 Class Zz Plus Plug Gage 19.34mm

Product Description

The VERMONT GAGE 112119340 is a Class ZZ Plus plug gage designed for precise go inspection of bored, reamed, or drilled holes with a nominal diameter of 19.34 mm. Manufactured from tool steel with a 10 micro-inch finish coating, this gage delivers a tolerance of 0.00508 mm, meeting the dimensional accuracy requirements of ASME B89.1. Each unit ships with a Certificate of Accuracy with NIST traceability, confirming calibration compliance for quality-controlled environments. Machinists, quality control technicians, and metrology professionals use this gage to verify that workpiece holes fall within specified limits before downstream assembly or inspection.

This plug gage is suited for production floor and inspection room use in manufacturing, machining, and precision fabrication environments. It is appropriate for go inspection applications and functions as a reference standard when setting micrometers, verniers, and other measuring devices. The 2.0000-inch overall length provides a comfortable handling profile for benchtop and in-process inspection tasks. It is typically applied in facilities that require traceable dimensional verification under ASME B89.1 standards.

Key Features

• Class ZZ Plus tolerance classification per ASME B89.1 for go inspection applications
• Nominal diameter of 19.34 mm with a tolerance of 0.00508 mm
• Tool steel construction with a 10 micro-inch finish coating for wear resistance and dimensional stability
• Includes Certificate of Accuracy with NIST traceability for calibration records
• Compatible with use as a setting standard for micrometers, verniers, and other measuring devices
• Overall length of 2.0000 inches for practical benchtop and in-process handling

Compatibility

Designed for go inspection of holes at 19.34 mm nominal diameter. Also serves as a setting reference for micrometers, verniers, and other measuring devices requiring a traceable dimensional standard.

Installation Notes

Plug gages should be handled with clean, dry hands or cotton gloves to prevent corrosion from skin oils. Store the gage in its case when not in use and allow it to reach ambient temperature before use if moved from a temperature-controlled environment. Do not force the gage into a hole; resistance indicates the feature is undersized and requires further machining. Calibration intervals should follow the facility quality management plan and applicable metrology standards.
