Vermont Gage 112201140 Class Zz Minus Plug Pin Gage 1.14 Mm

Product Description

The VERMONT GAGE 112201140 is a Class ZZ Minus plug pin gage machined from steel and used to perform NoGo inspection checks on bored holes, drilled passages, and precision-machined features. It measures a nominal diameter of 1.14 mm with a tolerance of 0.00508 mm, making it suitable for applications that demand tight dimensional verification. The gage measures 2 inches in overall length and weighs 0.01 pounds. Each unit ships with a Certificate of Accuracy traceable to NIST, satisfying documentation requirements for calibrated inspection tools. Machinists, quality technicians, and tool-and-die professionals use this type of gage as a fast, reliable attribute-inspection method in production and metrology environments.

This pin gage is designed for NoGo inspection work and is also used alongside set micrometers, verniers, and other precision measuring devices requiring a known-diameter reference. It fits into quality-control workflows where go/nogo attribute gaging is required to verify that a feature does not exceed its maximum material condition. The small diameter range makes it well suited for inspecting fine holes in precision components, medical parts, electronics housings, and similar close-tolerance work. The 10 microfinish surface coating contributes to repeatable seating and minimizes wear during repeated insertions.

Key Features

• 1.14 mm nominal diameter with 0.00508 mm Class ZZ Minus tolerance for tight NoGo inspection
• Steel construction with 10 microfinish surface for repeatable, low-wear gaging
• 2-inch overall length provides controlled handling in standard pin gage handles or collets
• Includes Certificate of Accuracy with NIST traceability for calibration recordkeeping
• Suitable for use with set micrometers, verniers, and other precision measuring instruments

Compatibility

Designed for use in standard pin gage handles and collet-style holders that accept sub-2 mm diameter pins. Suitable for NoGo attribute inspection of precision-bored holes and as a reference standard for setting micrometers, verniers, and similar measuring devices.

Installation Notes

Pin gages of this diameter are handled by quality technicians and precision machinists following standard metrology practices. Store the gage in its protective sleeve when not in use to prevent nicks or corrosion that would affect the calibrated diameter. Clean the gage and the feature being inspected before use to prevent debris from causing a false rejection or a false pass. Do not force the pin; a NoGo gage should not enter a conforming hole, and any resistance should be treated as a pass, not an obstruction to overcome.
