Vermont Gage 112203840 Class Zz Minus Plug Pin Gage 3.84mm

Product Description

The VERMONT GAGE 112203840 is a Class ZZ Minus plug pin gage designed for NoGo inspection applications in precision measurement and quality control environments. This single-pin gage measures 3.84 mm in diameter and holds a tolerance of 0.00508 mm, making it suitable for verifying that a bored hole or machined feature does not fall below the minimum allowable size. The gage is machined from steel and finished to a 10 microfinish surface for consistent, repeatable contact. Each unit ships with a Certificate of Accuracy with NIST traceability, confirming that the gage meets documented dimensional standards. Machinists, quality technicians, and inspection personnel use this tool alongside micrometers, verniers, and other precision measuring devices.

This pin gage is used in machine shops, manufacturing facilities, and inspection labs where tight dimensional tolerances must be verified on machined bores, drilled holes, and similar features. At 2 inches in overall length, it fits standard pin gage handles and is suited to bench-top and in-process inspection work. The NoGo designation means this gage is used to confirm rejection of oversize or out-of-tolerance features, working as part of a Go/NoGo gage set or as a standalone check against a specific limit. It is applicable wherever ISO or ASME dimensional inspection protocols are followed.

Key Features

• Class ZZ Minus tolerance class: 0.00508 mm tolerance for NoGo inspection use
• 3.84 mm diameter pin for direct bore and hole verification
• 10 microfinish surface coating for accurate, consistent contact
• Steel construction for durability in production and lab environments
• Includes Certificate of Accuracy with NIST traceability
• 2 inch overall length fits standard pin gage handles

Compatibility

Designed for use with standard pin gage handles and compatible with set micrometers, verniers, and other precision measuring devices as noted in the product specifications. Suitable for NoGo inspection setups wherever a 3.84 mm Class ZZ Minus pin is required.

Installation Notes

This gage is handled and used by quality technicians and machinists in inspection environments. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the steel surface. Do not force the pin into a feature; if it does not enter freely during a NoGo check, the part is within tolerance. Store in a protective case away from other tooling to avoid contact damage to the finished surface.
