Vermont Gage 111437750 Class Zz Minus Plug Pin Gage 0.3775 in

Product Description

The VERMONT GAGE 111437750 is a Class ZZ Minus plug pin gage designed for NoGo inspection applications in precision measurement workflows. This steel pin gage measures 0.3775 inches in diameter with an overall length of 2 inches and holds a tolerance of 0.0002 inches, making it suitable for verifying that bores, holes, and openings do not exceed a specified maximum size. It ships with a Certificate of Accuracy with NIST Traceability, confirming conformance to recognized measurement standards. Machinists, quality control technicians, and metrology professionals rely on pin gages like this one for fast, repeatable go/no-go inspections on the shop floor or in the inspection room.

This plug pin gage is used in manufacturing and machining environments where tight dimensional tolerances must be verified. The Class ZZ rating designates it for general-purpose inspection use. The NoGo designation means this gage is applied to confirm a hole or bore is not oversized beyond the allowable upper limit. It is also suitable for setting and checking micrometers, verniers, and other measuring devices requiring a known reference diameter. The 10 microfinish surface coating supports consistent, low-friction insertion into the feature being inspected.

Key Features

• Class ZZ Minus tolerance classification for general-purpose NoGo inspection
• 0.3775 inch diameter with a tolerance of 0.0002 inches for precise dimensional verification
• 2 inch overall length for comfortable handling and adequate reach
• Steel construction with a 10 microfinish surface for durability and smooth gage insertion
• Includes Certificate of Accuracy with NIST Traceability for documentation and calibration records
• Compatible with micrometer, vernier, and other measuring device setup applications

Compatibility

Designed for NoGo inspection use and for setting micrometers, verniers, and other measuring devices requiring a 0.3775 inch reference diameter. Suitable for general-purpose precision inspection in machining and manufacturing environments.

Installation Notes

Pin gages are installed and used by machinists, quality technicians, and metrologists — no special tools are required for standard hand-held inspection use. Store the gage in its protective case when not in use to prevent damage to the ground surface or corrosion of the steel. Do not force the pin into a feature; excessive insertion force can damage both the gage and the workpiece. Handle with clean, dry hands or lint-free gloves to preserve the surface finish and prevent corrosion from skin oils.
