Vermont Gage 112419250 Class Zz Minus Plug Pin Gage 19.25mm

Product Description

The VERMONT GAGE 112419250 is a Class ZZ minus plug pin gage used to perform NoGo inspection of machined bores and holes with a nominal diameter of 19.25 mm. Manufactured from steel with a 10 micro finish coating, it delivers a tolerance of 0.00508 mm, meeting Class ZZ minus standards for dimensional verification. Each gage ships with a Certificate of Accuracy traceable to NIST, supporting quality documentation requirements in production and inspection environments. Machinists, quality technicians, and tool room professionals use this type of gage as part of go/nogo inspection routines to confirm that a feature does not exceed its maximum allowable size.

This plug pin gage is suited for NoGo inspection applications in machine shops, manufacturing facilities, and metrology labs. It is also referenced when setting micrometers, verniers, and other measuring devices requiring a known reference standard. The 2-inch overall length provides a comfortable grip for hand-use inspection tasks. Its compact size and precise tolerance make it practical for both incoming inspection stations and in-process quality checks on production floors handling metric-dimensioned workpieces.

Key Features

• Class ZZ minus tolerance of 0.00508 mm for NoGo dimensional inspection
• 19.25 mm nominal measurement diameter in metric sizing
• Steel construction with 10 micro finish coating for wear resistance and dimensional stability
• Includes Certificate of Accuracy with NIST traceability for quality system documentation
• 2-inch overall length suited for hand-held inspection use
• Compatible as a reference standard for setting micrometers, verniers, and other measuring devices

Compatibility

Designed for NoGo inspection applications and for setting micrometers, verniers, and other measuring devices requiring a 19.25 mm metric reference standard.

Installation Notes

Plug pin gages are handled and used by quality technicians and machinists; no power source or mechanical installation is required. Store the gage in its protective case when not in use to prevent surface damage and corrosion. Clean the gage and the bore being inspected before use to ensure accurate readings and to avoid premature wear. Never force a plug gage into a feature; if resistance is felt during a NoGo check, the feature is within tolerance and the gage should be withdrawn without applied force.
