Vermont Gage 141149900 Class X Plus Pin Gage 0.499 in

Product Description

The VERMONT GAGE 141149900 is a Class X Plus precision pin gage designed for high-accuracy dimensional inspection work. Measuring 0.499 inches in diameter and 2 inches in length, this gage is manufactured from tool steel with a 4 micro-inch surface finish. Class X Plus represents the tightest commercially available tolerance grade, with a tolerance of +0.00004 inches on the nominal diameter. Each unit ships with a Certificate of Accuracy that carries NIST traceability, making it suitable for use in documented quality systems and calibration programs. Machinists, quality technicians, and metrology lab personnel use pin gages of this type as a reliable go/no-go reference or for direct part inspection.

This pin gage is suited for calibrating measuring equipment or for directly gaging bored holes, punched openings, and machined features that require close dimensional verification. Typical applications include incoming inspection, in-process quality checks, and calibration lab use across manufacturing, aerospace, automotive, and general machining environments. The 0.499-inch diameter targets hole features at or near that nominal size, and the 2-inch length provides adequate handling clearance for most bench and fixture inspection setups.

Key Features

• Class X Plus tolerance grade: +0.00004 inches for highest precision verification
• Tool steel construction for hardness, wear resistance, and dimensional stability
• 4 micro-inch surface finish for accurate, consistent contact measurement
• Includes Certificate of Accuracy with NIST traceability for quality documentation
• Compact 2-inch length suits bench inspection and tight-access applications

Compatibility

Designed as a direct-measurement and calibration reference for any inspection setup requiring a 0.499-inch nominal diameter pin gage at Class X Plus tolerance. Compatible with standard pin gage handles and gage block accessories used in metrology and quality inspection programs.

Installation Notes

Pin gages should be handled with clean, dry gloves or a lint-free cloth to prevent corrosion from skin oils. Store in the provided case or a dry, temperature-stable environment to maintain dimensional accuracy. When inserting into a feature, apply light axial pressure only — never force the gage or use it as a pry tool. Periodic recalibration intervals should follow your facility quality management procedures and applicable standards such as ASME B89.1.5.
