Vermont Gage 911205100 Class Zz Minus Plug Pin Gage 0.0510 in

Product Description

The VERMONT GAGE 911205100 is a Class ZZ Minus plug pin gage designed for NoGo inspection work in dimensional quality control applications. Machined from steel with a black oxide finish, this gage measures 0.0510 inches in diameter and holds a tolerance of 0.0002 inches. The overall length is 2 inches. It ships with a Certificate of Accuracy with NIST Traceability, making it suitable for use in calibrated measurement environments. Machinists, quality technicians, and tool-and-die professionals use pin gages like this one to verify bore diameters, hole sizes, and feature dimensions on production parts and assemblies.

This gage is intended for NoGo inspection procedures where a bore or hole must reject an oversized condition. It is also used to set micrometers, verniers, and other precision measuring devices requiring a known reference diameter. Typical applications include incoming inspection, in-process quality checks, and calibration setups in machine shops, manufacturing facilities, and metrology labs. The 0.0510 inch diameter targets small-bore inspection work common in precision machining and tooling environments.

Key Features

• 2 inch overall length for easy handling in small-bore applications
• Steel construction with black oxide finish for corrosion resistance and durability
• Includes Certificate of Accuracy with NIST Traceability
• Compatible with micrometers, verniers, and other precision measuring devices

Compatibility

Designed for use as a NoGo plug gage in standard inspection setups and as a reference standard for setting micrometers, verniers, and other precision measuring instruments requiring a 0.0510 inch diameter reference.

Installation Notes

Pin gages are handled and stored by quality technicians and metrologists following standard gage-handling procedures. Keep the gage clean and lightly oiled when not in use to prevent corrosion. Do not force the gage into a bore — if resistance is met during a NoGo check, the part is within specification and no additional force should be applied. Store in the original case or a designated gage block tray to prevent contact damage to the gage surface.
