Vermont Gage 141250100 Class X Minus Pin Gage 0.501 in

Product Description

The VERMONT GAGE 141250100 is a Class X Minus pin gage manufactured from tool steel, designed for high-precision measurement of bores, holes, and internal features. With a nominal diameter of 0.501 inches and a tolerance of -0.00004 inches, this gage holds the tightest standard classification for go/no-go and direct gaging work. The 4 microinch surface finish ensures accurate contact with the workpiece. Each unit ships with a Certificate of Accuracy with NIST traceability, making it suitable for use in calibrated measurement environments. Machinists, quality technicians, and metrology professionals use this type of pin gage in both shop-floor inspection and calibration lab applications.

This pin gage is used to calibrate measuring equipment or to directly gage parts in manufacturing and inspection settings. The 0.501-inch diameter covers a common bore size in precision machining. At 2 inches in length, it fits standard pin gage handles and accessories. Typical applications include incoming inspection, in-process quality control, and calibration of bore measurement tools. The Class X Minus designation indicates the gage is undersized within the tolerance band, used as the minus gage in a matched pair or as a standalone inspection tool where precise dimensional verification is required.

Key Features

• Class X Minus tolerance of -0.00004 inches for high-precision gaging

Compatibility

Designed as an OEM-style Class X Minus pin gage for use with standard pin gage handles and sets in precision measurement and calibration applications.

Installation Notes

Pin gages are handled by quality technicians and metrologists; install into a standard pin gage handle using clean, dry hands or lint-free gloves to avoid contaminating the gage surface. Clean the gage and the part bore with a lint-free cloth before use to remove chips, oil, or debris that could affect measurement accuracy. Store the gage in its protective case when not in use to prevent corrosion and surface damage. Do not force the gage into an undersized bore, as this can damage the gage surface and invalidate the Certificate of Accuracy.
