Vermont Gage 112301450 Class Zz Plus Plug Gage 1.45 Mm

Product Description

The VERMONT GAGE 112301450 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 coating, this gage checks whether a feature falls within acceptable tolerance limits during go inspection procedures. The working diameter measures 1.45 mm with a tolerance of 0.005 mm, delivering the tight accuracy required for quality control in machining, assembly, and metrology environments. Each unit ships with a Certificate of Accuracy traceable to NIST standards, meeting the requirements of ASME B89.1. Dimensional inspection professionals, quality technicians, and machinists rely on this type of gage for fast, repeatable pass/fail verification.

This plug gage is suited for go inspection use in manufacturing and quality assurance settings where small bore diameters must be verified to close tolerances. It is also compatible as a reference standard for setting micrometers, verniers, and other measuring devices requiring a certified dimensional reference. Typical applications include production floor inspection, incoming inspection of machined components, and calibration support tasks where a traceable 1.45 mm reference is required.

Key Features

• Class ZZ Plus tolerance class for precision go inspection per ASME B89.1
• 1.45 mm working diameter with 0.005 mm tolerance
• Tool steel construction for wear resistance and dimensional stability
• 10 microfinish surface for consistent, low-friction gage contact
• Includes Certificate of Accuracy with NIST traceability
• Suitable for setting micrometers, verniers, and other measuring devices

Compatibility

Designed for go inspection use with bores and features at a 1.45 mm nominal diameter. Also suitable for use as a reference standard when setting micrometers, verniers, and other measuring devices requiring a certified dimensional reference at this diameter.

Installation Notes

Plug gages of this type are handled and used by quality technicians and metrology professionals. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel body. Do not force the gage into a feature; apply only light, consistent hand pressure to avoid false readings or gage wear. Store in the supplied case or a protective holder away from temperature extremes to maintain dimensional accuracy.
