Vermont Gage 112209860 Class Zz Minus Plug Pin Gage 9.86 Mm

Product Description

The VERMONT GAGE 112209860 is a Class ZZ minus plug pin gage used to perform NoGo inspection of bored, reamed, and drilled holes. Machined from steel with a 10 microfinish surface coating, this pin gage checks whether a hole has exceeded its maximum allowable diameter. It measures 9.86 mm in diameter with a tolerance of 0.00508 mm, making it suitable for close-tolerance quality control work. Overall length is 2 inches. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting documentation requirements in calibrated inspection environments. Machinists, quality technicians, and tool-room professionals use this gage as part of go/nogo inspection routines on production and job-shop floors.

This pin gage is intended for NoGo hole inspection in manufacturing, machining, and metrology applications. It is also used to set micrometers, verniers, and other measuring devices requiring a known reference diameter. Typical use cases include incoming inspection, in-process quality checks, and final inspection of precision components where hole diameter must not exceed a specified limit. The 9.86 mm size fits applications common in general metalworking and precision machining operations.

Key Features

• Class ZZ minus tolerance of 0.00508 mm for NoGo inspection applications
• Steel construction with 10 microfinish surface coating for consistent gage wear and accurate readings
• Overall length of 2 inches for standard pin gage handle compatibility
• Includes Certificate of Accuracy with NIST traceability for calibrated inspection records
• Compatible with use as a reference for setting micrometers, verniers, and other measuring devices

Compatibility

Designed for use in standard pin gage handle sets and plug gage fixtures for NoGo hole inspection; also suitable for setting and verifying micrometers, verniers, and similar precision measuring instruments.

Installation Notes

Handle and use this gage with clean, dry hands or lint-free gloves to prevent corrosion and measurement error from contamination. Store the pin in its protective case when not in use and keep it away from magnetic fields and temperature extremes that can affect calibration. Quality technicians and metrology personnel should follow facility-specific gage handling and calibration interval procedures. Never force the pin into a hole; controlled hand pressure only prevents gage damage and ensures accurate inspection results.
