Vermont Gage 112301270 Class Zz Plus Plug Gage 1.27mm

Product Description

The VERMONT GAGE 112301270 is a Class ZZ Plus cylindrical plug gage designed to verify bore and hole dimensions to tight tolerances in production and inspection environments. With a 1.27 mm diameter and a tolerance of 0.00508 mm, this gage delivers precise go-inspection performance suited to quality control workflows. Constructed from tool steel and finished to a 10 microfinish surface, it provides the dimensional stability and surface integrity required for repeatable metrology results. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting ASME B89.1 standards. Machinists, quality technicians, and metrologists use this gage in both shop-floor and lab settings.

This plug gage is intended for go inspection applications where hole diameter acceptance must be verified against a known standard. It is also used to set and verify micrometers, verniers, and other measuring devices requiring a traceable reference. The 1.27 mm diameter makes it well suited for small-bore inspection tasks common in precision machining, medical device manufacturing, and electronics fabrication. Its compact overall length of 2.0000 inches supports use in confined inspection setups.

Key Features

Compatibility

Designed for go inspection of bores and holes at 1.27 mm diameter, and for setting micrometers, verniers, and other measuring devices requiring a traceable cylindrical reference standard.

Installation Notes

Plug gages are handled and used by quality technicians and metrologists; no mechanical installation is required. Store the gage in its protective case when not in use to prevent surface damage and contamination. Clean contact surfaces before use with a lint-free cloth to maintain measurement accuracy. Follow your facility's gage calibration and handling procedures in accordance with ASME B89.1 practices.
