Vermont Gage 112412070 Class Zz Minus Plug Pin Gage 12.07mm

Product Description

The VERMONT GAGE 112412070 is a Class ZZ Minus plug pin gage machined from steel for precision bore and hole inspection. The gage measures 12.07 mm in diameter and is manufactured to a tolerance of 0.00508 mm, meeting Class ZZ minus standards for NoGo inspection applications. It includes a Certificate of Accuracy with NIST traceability, making it suitable for documented quality-control programs. The 10 microfinish surface coating supports consistent, low-friction insertion during gauging. At an overall length of 2 inches, the pin provides adequate handling clearance for benchtop and in-line inspection work. Machinists, quality technicians, and metrology professionals rely on this type of gage to verify that a hole does not exceed its maximum material condition limit.

This pin gage is used in manufacturing and inspection environments where tight dimensional tolerances must be verified before parts advance to the next stage of production. Common applications include setting and verifying micrometers, verniers, and other measuring devices, as well as performing go/no-go hole inspection on machined components. The NoGo designation means the pin is intended to reject out-of-tolerance holes that are oversized beyond the specified limit. It is equally useful in toolroom settings, receiving inspection stations, and on the production floor wherever documented dimensional verification is required.

Key Features

• Class ZZ Minus tolerance of 0.00508 mm for NoGo inspection use
• Steel construction with 10 microfinish surface for repeatable, accurate gauging
• 12.07 mm nominal diameter, overall length of 2 inches
• Includes Certificate of Accuracy with NIST traceability for documented QC programs
• Suitable for setting micrometers, verniers, and other precision measuring devices

Compatibility

Designed as a NoGo plug pin gage for use with standard pin gage handles and sets where 12.07 mm diameter inspection is required. Compatible with micrometers, verniers, and other measuring devices needing a traceable reference standard.

Installation Notes

Pin gages should be handled by quality technicians or machinists familiar with precision metrology practices. Clean the gage and the bore to be inspected before use to prevent debris from affecting the gauging result or damaging the finished surface. Store the pin in its protective case when not in use to prevent surface damage that would affect accuracy. Do not force the pin gage into an undersized hole, as this can damage both the gage and the workpiece.
