Vermont Gage 112201740 Class Zz Minus Plug Pin Gage 1.74 Mm

Product Description

The VERMONT GAGE 112201740 is a Class ZZ Minus plug pin gage designed for precise dimensional inspection in manufacturing and metrology environments. This single-pin gage measures 1.74 mm in diameter with a tolerance of 0.00508 mm, making it suited for NoGo inspection applications where tight dimensional control is required. The gage is machined from steel and features a 10 microfinish surface coating. At 2 inches in overall length, it is a compact, handheld tool used by quality control inspectors and machinists to verify bore and hole dimensions against specification. Each unit ships with a Certificate of Accuracy that includes NIST traceability documentation.

This pin gage is intended for NoGo inspection use, verifying that a feature does not exceed its maximum allowable size. It is also suitable for setting and calibrating micrometers, verniers, and other measuring devices in shop or lab environments. Applications include incoming inspection, in-process quality checks, and calibration reference work in both production and toolroom settings. The compact diameter and steel construction make it appropriate for precision inspection of small bores and holes common in machined components.

Key Features

• Class ZZ Minus tolerance classification for NoGo inspection per ANSI standards
• 1.74 mm measurement diameter with 0.00508 mm tolerance
• Steel construction with 10 microfinish surface for consistent, accurate contact
• 2 inches overall length for comfortable single-hand use
• Includes Certificate of Accuracy with NIST traceability
• Suitable for setting micrometers, verniers, and other measuring instruments

Compatibility

Designed for use in NoGo bore inspection applications and as a setting reference for micrometers, verniers, and other precision measuring devices requiring a 1.74 mm diameter reference standard.

Installation Notes

Pin gages are handled and used by quality control technicians and machinists; no permanent installation is required. Store the gage in its protective case when not in use to prevent damage to the precision ground surface. Clean the gage and the bore being measured before use to ensure accurate readings. Handle with care to avoid dropping, as impact damage can alter the precision diameter and invalidate the calibration certificate.
