Vermont Gage 141134200 Class X Plus Pin Gage 0.342 in

Product Description

The VERMONT GAGE 141134200 is a Class X Plus pin gage used to verify bore diameters, check hole sizes, and calibrate measuring equipment to precise tolerances. It measures 0.342 inches in diameter and 2 inches in length, manufactured from tool steel with a 4 micro-inch surface finish. The Class X Plus tolerance grade holds to +0.00004 inches, making it one of the tightest commercially available tolerance classes for go/no-go and attribute gaging applications. Each unit ships with a Certificate of Accuracy that includes NIST traceability, supporting quality management systems and calibration documentation requirements. Machinists, quality technicians, and metrology lab personnel are the primary users.

This pin gage is suited for inspection and calibration work in machine shops, manufacturing facilities, and metrology labs. It is used to directly gage parts such as drilled, reamed, or bored holes, and to verify the accuracy of measuring equipment including CMMs and bore gages. The 0.342-inch diameter places it in a common range for fastener clearance hole verification and precision bore inspection in both production and tool room environments.

Key Features

• Class X Plus tolerance of +0.00004 inches for high-accuracy attribute gaging
• Tool steel construction for wear resistance and dimensional stability
• 4 micro-inch surface finish for consistent, reliable contact measurement
• Includes Certificate of Accuracy with NIST traceability for documentation and audit support
• Compact 2-inch length for easy handling in bench and fixture applications

Compatibility

Designed for use as a Class X Plus pin gage in standard go/no-go and attribute gaging setups for holes and bores requiring a 0.342-inch nominal diameter measurement.

Installation Notes

Pin gages should be handled with clean, lint-free gloves or wiped with a clean cloth to prevent corrosion from skin oils. Store in a protective case away from temperature extremes to maintain dimensional accuracy. Calibration intervals should be established per your quality management system procedures. No power source or mechanical installation is required.
