Vermont Gage 112301130 Class Zz Plus Plug Gage 1.13mm

Product Description

The VERMONT GAGE 112301130 is a Class ZZ Plus plug gage designed for precision dimensional inspection of small bores and holes. It measures 1.13 mm in diameter with a tolerance of 0.00508 mm, making it suitable for go inspection applications where tight dimensional control is required. Constructed from tool steel, the gage features a 10 microfinish surface coating to ensure consistent, accurate contact during measurement. The overall length is 2.0000 inches. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting quality documentation requirements in calibration and inspection environments. Metrology technicians, quality control inspectors, and tool room machinists are the primary users of this type of gage.

This plug gage is used in go inspection routines to verify that a drilled, reamed, or otherwise finished hole meets minimum dimensional requirements. It is also suitable for setting and verifying micrometers, verniers, and other precision measuring devices. Applications span manufacturing, machining, and quality assurance environments where ASME B89.1 compliance is required. The compact size and tool steel construction make it well suited for both bench inspection and in-process checks on production lines handling small-diameter features.

Compatibility

Designed for go inspection of bores and holes at 1.13 mm diameter; also used to set and verify micrometers, verniers, and other precision measuring devices per ASME B89.1 standards.

Installation Notes

Plug gages of this type are handled and used by metrology technicians and quality control inspectors. Clean the gage and the bore thoroughly before use to prevent contamination from affecting measurement results. Do not force the gage into a hole; apply only light, consistent hand pressure to avoid damage to the gage or the workpiece. Store the gage in its case when not in use to protect the lapped surface finish and maintain dimensional integrity.
