Vermont Gage 141118100 Class X Plus Pin Gage 0.181 in

Product Description

The VERMONT GAGE 141118100 is a Class X Plus precision pin gage used to verify bore diameters, hole sizes, and slot widths in machined and fabricated parts. It measures 0.181 inches in diameter and 2 inches in length, manufactured from tool steel with a 4 microinch surface finish. The tolerance is +0.00004 inches, placing it in the tightest commercially available class for go/no-go and attribute inspection work. Each unit ships with a Certificate of Accuracy traceable to NIST standards, making it suitable for use in calibrated inspection environments, quality labs, and production floor gauging stations.

This pin gage is used in dimensional inspection applications across manufacturing, machining, and metrology. It is suited for calibrating measuring equipment or for direct part gauging where hole location and diameter conformance must be confirmed. Typical users include quality control technicians, machinists, and metrology professionals working in job shops, production facilities, or calibration laboratories. The 2-inch length provides adequate grip and insertion depth for most standard inspection fixtures and bore applications at this diameter range.

Key Features

• Class X Plus tolerance of +0.00004 inches for high-precision attribute gauging
• Tool steel construction for hardness and dimensional stability
• 4 microinch surface finish for consistent contact and accurate measurement
• Includes Certificate of Accuracy with NIST traceability
• 0.181 inch diameter, 2 inch length — ready for direct part or fixture use

Compatibility

Designed for use as a precision attribute gauge in any inspection or calibration application requiring a Class X Plus pin gage at 0.181 inches diameter. Suitable for use with standard pin gage handles and gauge blocks compatible with this diameter range.

Installation Notes

Pin gages of this class are handled by quality technicians and metrologists; no power tools or utilities need to be shut down before use. Store in a protective case away from moisture and temperature extremes to preserve dimensional accuracy. Clean the gage and the feature being measured before insertion to prevent damage to the finish or false readings. Do not force the gage into an undersized hole, as this can alter the surface finish and invalidate the tolerance class.
