Vermont Gage 141159100 Class X Plus Pin Gage 0.591 in

Product Description

The VERMONT GAGE 141159100 is a Class X Plus precision pin gage manufactured from tool steel for use in dimensional inspection and calibration applications. It measures 0.591 inches in diameter and 2 inches in length, with a tolerance of +0.00004 inches — a Class X Plus specification that places it among the tightest-tolerance pin gages available for shop and lab use. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming that the gage meets stated tolerances at time of manufacture. The surface finish is held to 4 microinch Ra. Metrology technicians, quality control inspectors, and precision machinists use this type of gage for go/no-go checks and for calibrating measuring equipment.

This pin gage is suited for precision measurement tasks in manufacturing, machine shops, tool rooms, and metrology labs. It is used to verify bore diameters, check hole locations, and calibrate other measuring instruments where NIST-traceable documentation is required. The 0.591-inch diameter and 2-inch working length make it practical for both direct gaging of machined parts and as a reference standard. Industrial quality technicians and calibration professionals working to tight tolerances in aerospace, automotive, and general manufacturing will find this gage appropriate for their inspection protocols.

Key Features

• Class X Plus tolerance of +0.00004 inches for high-precision dimensional inspection
• Tool steel construction for hardness, wear resistance, and dimensional stability
• 4 microinch Ra surface finish for accurate contact measurement
• Includes Certificate of Accuracy with NIST traceability
• 0.591-inch diameter and 2-inch length for direct part gaging or instrument calibration

Compatibility

Designed as an OEM-style precision reference gage for use with standard pin gage handles and sets in metrology and quality control applications where a 0.591-inch diameter Class X Plus gage member is required.

Installation Notes

Pin gages should be handled with clean, dry hands or lint-free gloves to prevent corrosion from skin oils. Store the gage in its protective case when not in use to preserve surface finish and dimensional integrity. No power tools or torque is required for use; the gage is inserted by hand into the feature being inspected. Periodic recalibration against NIST-traceable standards is recommended to maintain measurement confidence over time.
