Vermont Gage 112215600 Class Zz Minus Plug Pin Gage 15.60 Mm

Product Description

The VERMONT GAGE 112215600 is a Class ZZ Minus plug pin gage designed for precise dimensional inspection of bored holes and machined features. Machined from steel with a 10 micro-inch finish coating, this gage measures a nominal diameter of 15.60 mm with a tolerance of 0.00508 mm. It ships with a Certificate of Accuracy traceable to NIST, making it suitable for use in calibration programs, quality control workflows, and production floor inspection. Overall length is 2 inches. Machinists, quality technicians, and metrologists rely on Class ZZ pin gages for reliable go/no-go determinations and for setting and verifying micrometers, verniers, and other measuring instruments.

This gage is intended for NoGo inspection applications where tight dimensional verification is required. It is commonly used alongside go gages in two-piece gage sets to confirm that a bored or reamed hole does not exceed the maximum allowable diameter. Appropriate for both job-shop and production environments, it supports setup verification of micrometers, vernier calipers, and similar measuring devices. The NIST-traceable certificate supports ISO 9001 and AS9100 quality management requirements where documented gage traceability is mandatory.

Key Features

• Class ZZ Minus tolerance class: 0.00508 mm, suited for NoGo inspection gaging
• Steel construction with 10 micro-inch surface finish for consistent contact and wear resistance
• NIST-traceable Certificate of Accuracy included for calibration documentation requirements
• 15.60 mm nominal measurement diameter, 2 inches overall length
• Compatible with micrometers, verniers, and other precision measuring devices for setup and verification

Compatibility

Designed for NoGo inspection gaging applications and for setting and verifying micrometers, verniers, and other precision measuring devices requiring a 15.60 mm reference diameter.

Installation Notes

Pin gages are handled and used by quality technicians and machinists; no power tools or utilities need to be isolated before use. Store the gage in its protective case and handle with clean, dry hands or cotton gloves to prevent corrosion and surface contamination. Do not force the gage into a hole; if resistance is felt beyond normal hand pressure during a NoGo check, the feature is at or near the correct dimensional limit. Periodically re-verify the gage against calibration standards per your facility quality plan to maintain traceability.
