Vermont Gage 141224800 Class X Minus Pin Gage 0.248 in

Product Description

The VERMONT GAGE 141224800 is a Class X Minus precision pin gage used to check hole diameters and calibrate measuring equipment in machine shops, quality control labs, and manufacturing environments. It measures 0.248 inches in diameter and 2 inches in length, with a tight tolerance of -0.00004 inches, making it suitable for high-accuracy go/no-go inspection work. Constructed from tool steel with a 4 microinch surface finish, it delivers consistent, repeatable measurements. Each unit ships with a Certificate of Accuracy with NIST traceability, supporting formal inspection and calibration documentation requirements.

This pin gage is designed for dimensional inspection of bored holes, drilled holes, and machined features where a 0.248-inch nominal diameter is the target size. It is commonly used by machinists, quality technicians, and metrology professionals in both production and inspection settings. The Class X tolerance class is one of the tightest available, making this gage appropriate for applications where close tolerances must be verified with high confidence. It is suitable for use in aerospace, automotive, and general precision manufacturing environments.

Key Features

• Class X Minus tolerance at -0.00004 inches for high-precision dimensional inspection
• 0.248-inch diameter and 2-inch length for standard pin gage applications
• Tool steel construction provides hardness and wear resistance for repeated use
• 4 microinch surface finish supports accurate contact measurement
• Includes Certificate of Accuracy with NIST traceability for documented calibration programs

Compatibility

Designed as an OEM-style replacement and standard inspection tool for use with pin gage sets and handles compatible with 0.248-inch diameter class pin gages in precision measurement and quality control applications.

Installation Notes

Pin gages are handled and used by quality technicians and machinists — no permanent installation is required. Always clean the gage and the feature being measured before use to prevent debris from affecting readings. Store in a protective case away from humidity and temperature extremes to preserve dimensional accuracy. Do not force the gage into an undersized hole, as this can damage the gage or the workpiece.
