Vermont Gage 112201940 Class Zz Minus Plug Pin Gage 1.94 Mm

Product Description

The VERMONT GAGE 112201940 is a Class ZZ Minus plug pin gage machined from steel and used to verify that a hole or bore does not exceed its maximum allowable size. At 1.94 mm in diameter with a tolerance of 0.00508 mm, this gage provides reliable NoGo inspection performance for precision measurement workflows. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming the dimensional integrity of the gage at the time of manufacture. The overall length is 2 inches, and the surface finish is held to 10 microfinish for consistent contact during inspection. Metrology technicians, machinists, and quality control inspectors use this type of gage in high-accuracy applications.

This pin gage is designed for NoGo inspection applications and is compatible with use alongside set micrometers, verniers, and other precision measuring devices. It suits production floor inspection, incoming quality control, and calibration lab environments where tight dimensional tolerances must be verified. The 1.94 mm diameter targets small-bore work typical in precision machined components. NIST-traceable documentation makes it appropriate for use in ISO-compliant and AS9100-regulated quality systems where traceability records are required.

Key Features

• Class ZZ Minus tolerance classification for NoGo inspection use
• 1.94 mm diameter with 0.00508 mm tolerance for precision bore verification
• Steel construction with 10 microfinish surface for repeatable contact
• Includes Certificate of Accuracy with NIST traceability
• 2 inch overall length for comfortable hand use and gauge stand compatibility

Compatibility

Designed for use in NoGo inspection applications alongside set micrometers, verniers, and other precision measuring devices. Suitable for any quality system requiring NIST-traceable pin gage documentation.

Installation Notes

Pin gages are handled and used by metrology technicians and machinists and do not require mechanical installation. Clean the gage pin and the bore being checked before use to prevent debris from affecting measurement accuracy. Store the gage in its protective sleeve or case when not in use to prevent surface damage. Do not force the pin into a bore, as this can damage the gage or the workpiece and compromise dimensional accuracy.
