Vermont Gage 141121300 Class X Plus Pin Gage 0.213 in

Product Description

The VERMONT GAGE 141121300 is a Class X Plus precision pin gage used to verify bore diameters, hole sizes, and slot widths to tight tolerances. It measures 0.213 inches in diameter and 2 inches in length, machined from tool steel with a 4 microinch surface finish. The tolerance is +0.00004 inches, placing it in the Class X Plus accuracy tier — the tightest class in the go/no-go gage spectrum. Each unit ships with a Certificate of Accuracy traceable to NIST. Dimensional metrologists, quality technicians, and machining professionals use this gage for incoming inspection, in-process checks, and calibration of measuring equipment.

This pin gage is suited for precision measurement applications in machine shops, manufacturing facilities, and calibration labs. Its 0.213-inch diameter makes it appropriate for checking corresponding hole and bore dimensions on machined parts, fixtures, and tooling. The NIST-traceable certificate supports use in ISO and AS9100 quality environments where documented traceability is required. It is handled by hand without special tooling and is stored individually to protect the finished surface.

Key Features

• Class X Plus tolerance of +0.00004 inches for high-precision dimensional verification
• Tool steel construction provides hardness and wear resistance for repeated use
• 4 microinch surface finish supports accurate, repeatable contact measurement
• Includes Certificate of Accuracy with NIST traceability for documented quality systems
• 0.213 inches diameter, 2 inches length — compact form for direct part gaging

Compatibility

Designed for use as a go/no-go or transfer gage in precision measurement of 0.213-inch nominal bores, holes, and slots. Compatible with standard pin gage handles and storage sets that accept individual gage pins of this diameter class.

Installation Notes

Pin gages require no installation in the traditional sense but should be handled with clean, dry hands or cotton gloves to prevent corrosion from skin oils. Before use, inspect the pin surface for nicks or burrs that could affect accuracy. Store individually in a protective case away from other metal tools to preserve the finish. Calibration professionals should follow ANSI and applicable quality management system procedures when using this gage for equipment calibration records.
