Vermont Gage 112210340 Class Zz Minus Plug Pin Gage 10.34 Mm

Product Description

The VERMONT GAGE 112210340 is a Class ZZ minus plug pin gage machined from steel and used to perform NoGo-side dimensional inspection on bored holes, machined bores, and precision-toleranced features. At 10.34 mm in diameter, it carries a tolerance of 0.00508 mm, meeting Class ZZ standards for go/no-go gauging applications. The gage body is finished to a 10 microfinish surface and ships with a Certificate of Accuracy traceable to NIST. Overall length is 2 inches. Machinists, quality technicians, and tool-room inspectors use this type of gage to verify that a hole has not been bored beyond its maximum material condition limit.

This pin gage is intended for NoGo inspection tasks across general machining, precision manufacturing, and quality control environments. It is also suited for setting and verifying micrometers, verniers, and other comparative measuring devices where a traceable reference standard is required. The minus designation indicates the gage is ground to the lower side of the nominal diameter, which is the correct configuration for a NoGo member in a plug gage set. Applicable in both job-shop and production inspection settings handling metric-dimensioned workpieces.

Key Features

• Class ZZ minus tolerance configuration for NoGo-side bore inspection
• 10.34 mm nominal diameter with 0.00508 mm tolerance
• Steel construction with 10 microfinish surface for consistent contact and wear resistance
• Certificate of Accuracy included with NIST traceability
• 2-inch overall length suitable for standard gage handle mounting
• Suitable for setting micrometers, verniers, and other precision measuring instruments

Compatibility

Designed as an OEM-style replacement or direct-use Class ZZ minus plug pin gage for NoGo inspection of 10.34 mm diameter bores; compatible with standard gage handles sized for pin gages of this diameter range.

Installation Notes

Pin gages of this class are handled and stored by metrology technicians or quality control personnel following standard gage-handling procedures. Keep the gage clean and lightly oiled when stored to prevent corrosion on the steel body. Do not force the gage into a bore; NoGo gages should not enter a correctly sized hole under hand pressure. Periodic recalibration against a NIST-traceable standard is recommended to maintain measurement integrity.
