Vermont Gage 112100960 Class Zz Plus Plug Gage 0.96mm

Product Description

The VERMONT GAGE 112100960 is a Class ZZ Plus plug gage designed for precision dimensional inspection of small-diameter bores and holes. Manufactured from tool steel with a 10 microfinish surface, this gage measures a nominal diameter of 0.96 mm with a tolerance of 0.00508 mm, meeting the requirements of ASME B89.1. Each unit ships with a Certificate of Accuracy traceable to NIST, making it suitable for quality control applications where documented calibration traceability is required. Licensed metrology technicians, machinists, and quality inspectors rely on this class of gage for reliable go-inspection work in production and calibration environments.

This plug gage is intended for go inspection of precision bores and is also used to set micrometers, verniers, and other measuring devices requiring a known reference diameter. With an overall length of 2.0 inches, it is sized for bench and hand-held use in shop floor and metrology lab settings alike. Applications include incoming inspection, in-process quality checks, and calibration of variable measuring instruments. It is appropriate for both light manufacturing and high-precision production environments where tight tolerance verification is required.

Key Features

• Class ZZ Plus tolerance grade with 0.00508 mm tolerance for precision go inspection
• Tool steel construction for durability and dimensional stability
• 10 microfinish surface for consistent, repeatable gage contact
• Meets ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST traceability for quality documentation
• Compact 2.0-inch overall length suited for bench and hand use

Compatibility

Designed for use as a go plug gage for 0.96 mm diameter bores and as a reference standard for setting micrometers, verniers, and other precision measuring devices requiring a certified small-diameter reference.

Installation Notes

Plug gages should be handled and stored by qualified metrology personnel or trained machinists following established gage-care procedures. Before use, clean the gage and the bore being inspected to remove chips, coolant, and debris that could affect measurement accuracy. Never force a plug gage into an undersized bore, as this can damage the gage surface and alter its calibration. Periodic recalibration against NIST-traceable standards is recommended to maintain measurement integrity.
