Vermont Gage 112405130 Class Zz Minus Plug Pin Gage

Product Description

The VERMONT GAGE 112405130 is a Class ZZ Minus plug pin gage used to perform NoGo inspection of precision bored holes and machined features. It measures a nominal diameter of 5.13 mm with a tolerance of 0.00508 mm, providing reliable go/no-go verification in quality control and dimensional inspection workflows. The gage is machined from steel and features a 10 microfinish surface coating for consistent, repeatable contact. It ships with a Certificate of Accuracy traceable to NIST, supporting documentation requirements in calibrated inspection environments. Licensed metrology technicians, machinists, and quality control inspectors are the primary users of this tool.

This plug pin gage is suited for inspecting bored holes, drilled passages, and machined bores in manufacturing and machine shop environments. The Class ZZ Minus designation makes it appropriate for NoGo inspection use, confirming that a feature has not exceeded its maximum allowable size. It is also compatible with use alongside set micrometers, verniers, and other measuring devices where a reference gage standard is needed. At an overall length of 2 inches, the gage fits standard pin gage handles and holders used in bench inspection setups.

Key Features

• Class ZZ Minus tolerance class with 0.00508 mm tolerance for precise NoGo inspection
• 5.13 mm nominal measurement diameter
• Steel construction with 10 microfinish surface coating for consistent contact and wear resistance
• Includes Certificate of Accuracy with NIST traceability for calibration documentation
• Overall length of 2 inches for compatibility with standard pin gage handles

Compatibility

Designed for NoGo inspection applications and for use with set micrometers, verniers, and other measuring devices requiring a precision reference pin gage standard.

Installation Notes

Pin gages are handled by metrology technicians and quality control personnel in inspection or machine shop settings. Clean the gage and the feature to be measured before use to avoid debris affecting measurement accuracy. Store the gage in its protective case when not in use to prevent surface damage to the precision ground finish. Do not force the gage into a bore; apply only light, consistent hand pressure during inspection.
