Vermont Gage 111302850 Class Zz Plus Plug Gage 0.0285 in

Product Description

The VERMONT GAGE 111302850 is a Class ZZ Plus plug gage designed for precision dimensional inspection of small bores and holes at 0.0285 inches diameter. Built from tool steel with a 10 microfinish surface, this gage delivers repeatable go-inspection results within a tolerance of 0.0002 inches. It conforms to ASME B89.1 standards and ships with a Certificate of Accuracy with NIST Traceability, making it suitable for calibrated measurement environments. Machinists, quality technicians, and metrology professionals use this gage to verify hole size conformance in production and inspection settings.

This plug gage is used in go inspection applications where tight bore tolerances must be verified quickly and reliably. It is also suited for setting micrometers, verniers, and other measuring devices requiring a traceable reference standard. At 2.0 inches overall length, it is sized for easy single-hand use on bench or floor inspection tasks in both job shop and production environments. Its small diameter makes it appropriate for precision work on tightly toleranced components found in aerospace, medical device, and general machining applications.

Key Features

• Class ZZ Plus tolerance rating at plus or minus 0.0002 inches for high-accuracy go inspection
• 10 microfinish surface for smooth, consistent gage insertion without part damage
• Conforms to ASME B89.1 dimensional standards
• Includes Certificate of Accuracy with NIST Traceability for calibration documentation
• Tool steel construction for durability and wear resistance in regular inspection use
• Compact 2.0 inches overall length for easy handling in bench inspection work

Compatibility

Designed as an OEM-style go inspection plug gage for use with standard gage handle holders accepting wire-size and small-diameter gage members, and suitable for setting micrometers, verniers, and other precision measuring devices requiring a traceable reference.

Installation Notes

Plug gages of this type are handled and used by quality technicians and machinists following established metrology practices. Store the gage in its protective case when not in use to prevent surface damage and corrosion. Clean the gage member and the bore being inspected before each use to ensure accurate results. Calibration intervals should follow facility quality system requirements and applicable standards such as ASME B89.1.
