Vermont Gage 112401270 Class Zz Minus Plug Pin Gage 1.27 Mm

Product Description

The VERMONT GAGE 112401270 is a Class ZZ Minus plug pin gage designed for precise dimensional inspection at a nominal diameter of 1.27 mm. Manufactured from steel with a 10 microfinish surface coating, this pin gage holds a tolerance of 0.00508 mm, meeting Class ZZ minus standards for NoGo inspection applications. At 2 inches in overall length and weighing approximately 0.01 pounds, it is a compact, single-pin instrument used by quality control technicians and metrology professionals to verify that a hole or feature does not exceed its maximum material condition limit.

This pin gage is suited for NoGo inspection tasks on precision-machined components where tight dimensional conformance is required. It is also used for setting and calibrating micrometers, verniers, and other measuring devices in a shop or laboratory environment. Each unit ships with a Certificate of Accuracy with NIST Traceability, making it appropriate for ISO-compliant quality systems and regulated production environments. It is typically used in manufacturing, aerospace, automotive, and general precision machining applications.

Key Features

• Class ZZ Minus tolerance of 0.00508 mm for NoGo dimensional inspection
• Steel construction with 10 microfinish surface coating for consistent gauge contact
• 2 inches overall length for easy handling and gage stand mounting
• Includes Certificate of Accuracy with NIST Traceability
• Suitable for setting micrometers, verniers, and other precision measuring devices

Compatibility

Designed for NoGo inspection use and for setting micrometers, verniers, and other measuring devices requiring a 1.27 mm reference diameter. Verify nominal diameter and tolerance class against your inspection specification before use.

Installation Notes

Pin gages are handled by metrology and quality control personnel following standard gauge handling procedures. Keep the gage clean and lightly oiled when stored to prevent corrosion on the steel surface. Do not force the pin into a feature; apply only the light, consistent contact pressure appropriate for precision gauging. Store separately from harder tooling to avoid surface damage that would affect measurement accuracy.
