Vermont Gage 111188300 Class Zz Plus Plug Gage 0.883 in

Product Description

The VERMONT GAGE 111188300 is a Class ZZ Plus plug gage designed for precision dimensional inspection in toolroom and production environments. The gage measures a nominal diameter of 0.883 inches with a tolerance of 0.0002 inches and a 10 microinch surface finish, providing the accuracy required for Go inspection applications. Constructed from tool steel, it delivers the hardness and dimensional stability expected in a high-cycle gauging environment. Each unit ships with a Certificate of Accuracy with NIST traceability, confirming conformance to ASME B89.1 standards. Machinists, quality technicians, and metrologists rely on this type of gage for repeatable, traceable inspection results.

This plug gage is suited for Go inspection of bored holes, machined bores, and precision-drilled features at the 0.883-inch nominal diameter. It is also appropriate for setting and calibrating micrometers, vernier calipers, and other dimensional measuring devices where a certified reference standard at this diameter is required. Typical applications span precision machining shops, aerospace component inspection, and general manufacturing quality control where ASME B89.1 compliance is specified.

Key Features

• Class ZZ Plus tolerance of 0.0002 inches for high-accuracy Go inspection
• 10 microinch surface finish on the gaging surface for reliable, repeatable contact
• Tool steel construction for durability and dimensional stability under repeated use
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 dimensional standards
• Overall length of 2.0 inches for ergonomic single-hand use

Compatibility

Designed for Go inspection of features at a 0.883-inch nominal diameter and for use as a reference setting standard with micrometers, vernier calipers, and other dimensional measuring devices.

Installation Notes

Plug gages are handled and used by quality technicians and toolroom machinists — no installation in the traditional sense is required. Keep the gaging surfaces clean and lightly oiled when not in use to prevent corrosion on the tool steel. Never force the gage into a bore; if resistance is encountered, the feature is out of tolerance or the bore requires cleaning. Store in the provided case or a protected location to avoid surface damage that would affect calibration.
