Vermont Gage 112408650 Class Zz Minus Plug Pin Gage 8.65mm

Product Description

The VERMONT GAGE 112408650 is a Class ZZ Minus plug pin gage designed to perform NoGo inspection of bored, reamed, or machined holes to a nominal diameter of 8.65 mm. Built from steel with a 10 microfinish surface coating, this gage delivers a tolerance of 0.00508 mm, meeting Class ZZ dimensional standards. At 2 inches in overall length, it handles easily in both bench and floor inspection settings. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting documentation requirements for ISO and quality-system audits. Metrology technicians, tool room machinists, and quality control inspectors rely on this type of gage for fast, repeatable attribute inspection.

This plug pin gage is used in manufacturing environments where hole diameter acceptance or rejection must be verified quickly and reliably. Its NoGo designation means it confirms that a hole has not been bored oversize beyond the allowable tolerance. Typical applications include incoming inspection, in-process quality checks on machined components, and calibration verification of micrometers, verniers, and other measuring devices. It is suited for both production floor use and toolroom metrology benches.

Key Features

• Class ZZ Minus tolerance of 0.00508 mm for NoGo attribute inspection
• 8.65 mm nominal diameter for precise hole-size verification
• Steel construction with 10 microfinish surface for smooth, repeatable gaging
• 2 inches overall length for comfortable single-hand operation
• Includes Certificate of Accuracy with NIST traceability for audit compliance
• Suitable for use with micrometers, verniers, and other precision measuring devices

Compatibility

Designed as a NoGo plug pin gage for verifying 8.65 mm diameter holes; also suitable for setting and verifying micrometers, verniers, and comparable precision measuring instruments per Class ZZ standards.

Installation Notes

Plug pin gages are handled and applied by quality control technicians or tool room metrology staff and require no power or mechanical installation. Keep the gage clean and lightly oiled when stored to prevent corrosion on the steel body. Do not force the gage into a hole; a properly sized NoGo gage should not pass. Store in a temperature-stable environment to preserve dimensional accuracy and NIST-traceable certification validity.
