Vermont Gage 912201100 Class Zz Plug Pin Gage 1.10 Mm

Product Description

The VERMONT GAGE 912201100 is a Class ZZ minus-tolerance plug pin gage used to verify NoGo dimensional limits in precision inspection work. This pin gage measures 1.10 mm in diameter and has an overall length of 2 inches. The body is machined from steel with a black oxide finish that resists corrosion and reduces light reflection during inspection. Each unit ships with a Certificate of Accuracy traceable to NIST, making it suitable for documented quality-control environments. Machinists, toolroom technicians, and quality inspectors use this type of gage to check bore and hole dimensions against specified tolerances.

This pin gage is sized for inspection applications requiring a NoGo check at the 1.10 mm nominal diameter. It is also compatible with setup and calibration tasks involving set micrometers, verniers, and other measuring devices. The Class ZZ designation places this gage in the working-gage category, appropriate for production floor and inspection bench use where repeatable, low-cost dimensional verification is needed. The minus tolerance of 0.00508 mm ensures the pin stays within the correct ZZ class boundary for NoGo function.

Key Features

• Class ZZ minus tolerance of 0.00508 mm for NoGo inspection applications
• 1.10 mm measurement diameter with 2-inch overall length
• Steel construction with black oxide finish for corrosion resistance
• Includes Certificate of Accuracy with NIST traceability for documented QC use
• Compatible with set micrometers, verniers, and other precision measuring devices

Compatibility

Designed for NoGo bore and hole inspection at the 1.10 mm diameter, and for use with set micrometers, verniers, and other measuring devices requiring a calibrated reference pin.

Installation Notes

Pin gages are handled by quality technicians and toolroom personnel. Before use, clean the gage and the workpiece bore with a lint-free cloth to remove oils and debris that can affect measurement accuracy. Do not force the pin into a bore. Store pin gages in the protective sleeve or case when not in use to prevent damage to the gage surface.
