Vermont Gage 112308650 Class Zz Plus Plug Gage 8.65 Mm

Product Description

The VERMONT GAGE 112308650 is a Class ZZ Plus plug gage machined from tool steel for dimensional inspection work. It measures 8.65 mm in diameter with a tolerance of 0.005 mm, making it suitable for go inspection applications where tight dimensional control is required. The gage carries a 10 microfinish surface finish and ships with a Certificate of Accuracy traceable to NIST. Overall length is 2.0000 inches. Machinists, quality technicians, and metrology professionals use this type of gage to verify hole diameters against specification during in-process or final inspection.

This plug gage is intended for go inspection of 8.65 mm diameter bores in production and quality control environments. It is compatible with standard gage handle systems and is used alongside set micrometers, verniers, and other measuring devices to confirm dimensional conformance. Applicable in both job shop and high-volume manufacturing settings, it is well suited for any application requiring ASME B89.1 compliant dimensional verification of small-diameter internal features.

Key Features

• 8.65 mm diameter with 0.005 mm tolerance for precise go inspection
• Class ZZ Plus classification per ASME B89.1
• Tool steel construction for durability and wear resistance
• 10 microfinish surface finish for consistent gage contact
• Includes Certificate of Accuracy with NIST traceability
• Overall length of 2.0000 inches for standard gage handle compatibility

Compatibility

Designed for use with standard plug gage handles and suitable for go inspection of 8.65 mm internal bores. Intended for use with set micrometers, verniers, and other measuring devices per the application noted in the product data.

Installation Notes

Plug gages should be handled and stored in accordance with standard metrology practices to prevent damage to the ground surfaces. Clean the gage and the bore being inspected before use to ensure accurate measurement. Do not force the gage into a bore; hand pressure only should be used to prevent gage wear or bore damage. Periodic recalibration against NIST-traceable standards is recommended to maintain measurement integrity.
