Vermont Gage 112104800 Class Zz Plus Plug Gage 4.8mm

Product Description

The VERMONT GAGE 112104800 is a Class ZZ Plus cylindrical plug gage designed for go inspection of bores and holes with a 4.80 mm nominal diameter. Manufactured from tool steel with a 10 microfinish surface coating, it delivers the precision and repeatability that dimensional inspection work demands. The tolerance is 0.00508 mm, keeping measurement error within the tightest acceptable limits for ZZ-class gaging. Each unit ships with a Certificate of Accuracy that carries NIST traceability, meeting the documentation requirements of quality management systems. Licensed metrologists, quality technicians, and precision machinists rely on this gage for in-process and final inspection tasks.

This plug gage is suited for go-inspection applications in manufacturing environments where bore diameter must be confirmed before a part moves to the next stage. It is also used to set and verify micrometers, verniers, and other precision measuring devices. The compact overall length of 2.0000 inches makes it easy to handle in tight inspection setups. It is appropriate for both production floor checks and tool room calibration work wherever a 4.80 mm reference standard is required.

Key Features

• Class ZZ Plus tolerance of 0.00508 mm for high-accuracy go inspection
• Tool steel construction for durability and dimensional stability
• 10 microfinish surface coating minimizes wear on the gage and the workpiece bore
• NIST-traceable Certificate of Accuracy included for quality system compliance
• Meets ASME B89.1 standards for plain gages
• Overall length of 2.0000 inches for compact, practical handling

Compatibility

Designed for go inspection of features with a 4.80 mm nominal diameter and for use in setting and verifying micrometers, verniers, and other precision measuring devices as noted by the manufacturer.

Installation Notes

Plug gages are handled and used by quality technicians and metrologists in accordance with ASME B89.1 gaging practices. Store the gage in its protective case when not in use to prevent corrosion and surface damage. Clean the gage and the workpiece bore with a lint-free cloth before each use to avoid false readings caused by debris or oil film. Do not force the gage into a bore; apply only light hand pressure to protect the precision-ground surface.
