Vermont Gage 112201880 Class Zz Minus Plug Pin Gage 1.88 Mm

Product Description

The VERMONT GAGE 112201880 is a Class ZZ Minus plug pin gage designed for precision dimensional inspection in manufacturing and quality control environments. Measuring 1.88 mm in diameter with a tolerance of 0.00508 mm, this gage is used to verify that a hole or bore does not exceed its maximum allowable size, functioning as a NoGo inspection tool. The steel construction and 10 microfinish surface coating ensure consistent, repeatable contact during measurement. Each unit ships with a Certificate of Accuracy that includes NIST traceability, making it suitable for calibrated inspection programs. Machinists, quality technicians, and metrologists are the primary users.

This plug pin gage is applied in NoGo go-gage inspection routines on the shop floor or in quality labs. It is also used to calibrate and verify the accuracy of micrometers, verniers, and other precision measuring devices. The 2-inch overall length provides a comfortable, stable grip during inspection. It is well suited for close-tolerance work in industries where millimeter-scale bore acceptance or rejection must be documented and traceable to national standards.

Key Features

• 1.88 mm measurement diameter with 0.00508 mm tolerance
• Steel construction with 10 microfinish surface coating for consistent contact
• Includes Certificate of Accuracy with NIST traceability
• Compatible with micrometers, verniers, and other precision measuring devices
• 2-inch overall length for controlled, stable handling

Compatibility

Designed for use in NoGo inspection routines and for setting or verifying micrometers, verniers, and other precision measuring devices requiring a 1.88 mm reference diameter.

Installation Notes

Pin gages should be handled with clean, dry hands or lint-free gloves to prevent corrosion and measurement error. Store the gage in its protective case when not in use to preserve the surface finish and dimensional integrity. Periodic recalibration against a certified reference standard is recommended as part of any ISO or quality management program. Do not force the gage into a bore — light, consistent insertion pressure is required for accurate NoGo determination.
