Vermont Gage 111437350 Class Zz Plug Pin Gage 0.3735 in

Product Description

The VERMONT GAGE 111437350 is a Class ZZ Minus plug pin gage designed for NoGo inspection applications in precision measurement workflows. Machined from steel with a 10 microfinish coating, this pin gage measures 0.3735 inches in diameter with a tolerance of 0.0002 inches. At 2 inches in overall length, it is sized for straightforward handling in bore, hole, and feature inspection tasks. Each unit ships with a Certificate of Accuracy that includes NIST traceability, making it suitable for documented quality control processes in tool rooms, machine shops, and inspection departments.

This pin gage is used for NoGo inspection of bored holes, drilled features, and precision-machined openings requiring verification at the 0.3735-inch diameter threshold. It is also applicable for setting and checking micrometers, verniers, and other measuring devices where a traceable reference standard is required. Typical users include machinists, quality control technicians, and metrologists working in both production and toolroom environments. The Class ZZ designation indicates this is a general-purpose inspection grade gage suited for shop-floor and bench use.

Compatibility

Designed for NoGo inspection of features at 0.3735 inches diameter and for use as a reference standard when setting micrometers, verniers, and comparable precision measuring devices.

Installation Notes

Plug pin gages are handled and used by quality control technicians and machinists; no power tools or utility shutoffs are required for use. Keep the gage clean and lightly oiled when stored to prevent corrosion and protect the precision ground surface. Avoid dropping or forcing the gage into a feature, as this can alter the ground diameter and invalidate calibration. Store the Certificate of Accuracy with the gage to maintain documentation continuity for audits and inspection records.
