Vermont Gage 111423650 Class Zz Minus Plug Pin Gage 0.2365 in

Product Description

The VERMONT GAGE 111423650 is a Class ZZ Minus plug pin gage machined to a 0.2365-inch diameter for NoGo inspection work. Pin gages in this class are ground and lapped to tight tolerances, allowing machinists and quality inspectors to verify that a hole or bore does not exceed its maximum allowable size. The 111423650 carries a tolerance of 0.0002 inches and ships with a Certificate of Accuracy traceable to NIST, making it suitable for controlled inspection environments and calibration documentation requirements. The overall length of 2 inches provides adequate handling clearance for bench and floor-level inspection tasks.

This gage is used in machine shops, manufacturing facilities, and toolrooms wherever hole-size verification is part of a dimensional inspection routine. The NoGo designation means it is applied as the rejecting member of a go/no-go gage pair, confirming that a feature has not been oversized beyond tolerance. It is also suited for setting and checking micrometers, verniers, and other measuring devices that require a traceable reference standard. Applications span general metalworking, aerospace component inspection, and any production environment operating to close dimensional tolerances.

Key Features

• Class ZZ Minus tolerance class ground to 0.0002 inches for NoGo inspection use
• 0.2365-inch measurement diameter machined to a 10 microfinish surface finish
• Steel construction for durability and dimensional stability under shop conditions
• Overall length of 2 inches for comfortable single-hand operation
• Includes Certificate of Accuracy with NIST traceability for documented inspection programs
• Compatible with setting micrometers, verniers, and other precision measuring devices

Compatibility

Designed as a NoGo inspection gage and reference standard for use with micrometers, verniers, and other precision measuring devices requiring a traceable reference at 0.2365 inches.

Installation Notes

Pin gages are handled by metrology technicians, quality inspectors, and machinist personnel. Keep the gage surface free of oils, chips, and debris before and after each use to preserve the 10 microfinish and prevent measurement error. Store in the provided case or a clean, dry gage block cabinet to avoid corrosion and accidental damage. Do not force the gage into a feature; resistance indicates the bore is at or below the NoGo limit.
