Vermont Gage 141132400 Class X Plus Pin Gage 0.324 in

Product Description

The VERMONT GAGE 141132400 is a Class X Plus precision pin gage machined from tool steel for direct part gaging and calibration of measuring equipment. It measures 0.324 inches in diameter and 2 inches in length, holding a tight tolerance of plus 0.00004 inches — the tight tolerance standard that defines Class X Plus designation. The surface finish is held to 4 microinch Ra, supporting accurate contact measurement in close-tolerance inspection work. Each unit ships with a Certificate of Accuracy bearing NIST traceability, making it suitable for documented calibration programs and quality-system audits. Machinists, tool-and-die technicians, and quality control inspectors use this gage in shop-floor and metrology lab environments.

This pin gage is used to verify bore diameters, check hole locations, and calibrate measuring instruments in both production and inspection settings. Its 0.324-inch diameter makes it appropriate for go/no-go inspection of corresponding bores and holes where close-tolerance verification is required. Typical applications include dimensional inspection of machined components, fixture verification, and incoming-inspection routines across manufacturing, aerospace, and general-precision trades. The included NIST-traceable Certificate of Accuracy supports ISO 9001 and AS9100 quality management documentation requirements.

Key Features

• Class X Plus tolerance of plus 0.00004 inches for high-precision gaging applications
• Tool steel construction for hardness, wear resistance, and dimensional stability
• 4 microinch Ra surface finish for reliable contact measurement
• 2 inch usable length accommodates a range of bore depths and fixture setups
• Includes Certificate of Accuracy with NIST traceability for documented calibration programs

Compatibility

Designed as an OEM-style precision measurement tool suitable for use with standard pin gage handle sets and compatible with inspection procedures requiring Class X Plus tolerances at 0.324 inches diameter.

Installation Notes

Pin gages should be handled with clean, dry hands or lint-free gloves to prevent corrosion and measurement error from skin oils. Store in a protective case away from magnetic fields and temperature extremes to maintain dimensional integrity. When inserting into a bore, apply light, controlled force — never force a pin gage, as this can damage both the gage and the workpiece. Periodic recalibration against a NIST-traceable standard is recommended as part of any formal measurement system analysis program.
