Vermont Gage 112400890 Class Zz Minus Plug Pin Gage 0.89 Mm

Product Description

The VERMONT GAGE 112400890 is a Class ZZ Minus plug pin gage designed for precision dimensional inspection of small bores and holes. This steel pin gage measures 0.89 mm in diameter and carries a tolerance of 0.00508 mm, making it suitable for NoGo inspection applications where tight dimensional control is required. The overall length is 2 inches, with a 10 microfinish surface coating for consistent contact and repeatable measurement results. Each unit ships with a Certificate of Accuracy traceable to NIST standards. Quality control technicians and metrology professionals use this gage in production and inspection environments where millimeter-scale bore verification is critical.

This plug pin gage is used in precision measurement and quality assurance settings where small-diameter bore inspection is required. It is well suited for use alongside micrometers, verniers, and other measuring devices during NoGo inspection procedures. The 0.89 mm diameter makes it applicable to close-tolerance machined components found in industries such as medical device manufacturing, aerospace, and precision machined parts production. It is appropriate for both in-process inspection and final acceptance gauging on production floors or in dedicated metrology labs.

Compatibility

Designed for use in NoGo inspection procedures and compatible with standard micrometers, verniers, and other precision measuring devices requiring a 0.89 mm diameter reference pin.

Installation Notes

Pin gages are handled and used by quality control technicians and metrology professionals rather than installed in a mechanical system. Handle with clean, dry hands or lint-free gloves to prevent corrosion and measurement error. Store in a protective case away from temperature extremes to maintain dimensional stability and protect the precision finish. Follow standard metrology lab practices for calibration intervals and handling of NIST-traceable instruments.
