Vermont Gage 141239800 Class X Minus Pin Gage 0.398 in

Product Description

The VERMONT GAGE 141239800 is a Class X Minus pin gage used to verify bore diameters and check machined part features to tight dimensional tolerances. Manufactured from tool steel with a 4 microinch surface finish, this pin gage measures 0.398 inches in diameter and 2 inches in length. It carries a minus tolerance of 0.00004 inches, placing it within Class X specifications for high-precision measurement work. Each unit ships with a Certificate of Accuracy traceable to NIST standards, making it suitable for use in calibrated measurement environments. Machinists, quality technicians, and metrologists rely on this type of gage for direct part inspection and calibration of measuring equipment.

This pin gage is appropriate for use in manufacturing, quality control, and tool-room environments where precise hole and bore verification is required. It is suited for both shop-floor inspection and laboratory calibration applications. The 0.398-inch nominal diameter targets a specific measurement range commonly encountered in precision machined components. Its compact 2-inch length allows use in standard pin gage handles and holders for efficient inspection workflows.

Key Features

• Class X Minus tolerance of 0.00004 inches for high-precision dimensional verification
• Tool steel construction for durability and dimensional stability
• 4 microinch surface finish for accurate, repeatable contact measurement
• Includes Certificate of Accuracy with NIST traceability
• 0.398-inch nominal diameter, 2-inch length for standard pin gage handle compatibility

Compatibility

Designed for use with standard pin gage handles and holders that accept 0.398-inch diameter pin gages. Suitable for calibration of measuring equipment or direct inspection of machined parts requiring Class X Minus tolerance verification.

Installation Notes

Pin gages should be handled with clean cotton gloves or lint-free cloths to prevent corrosion and contamination of the precision surface. Before use, inspect the gage surface for nicks or wear that could affect measurement accuracy. Store in a protective case away from other tools to maintain the surface finish and dimensional integrity. Calibration intervals should follow your facility quality management procedures.
