Vermont Gage 141251100 Class X Minus Pin Gage 0.511 in

Product Description

The VERMONT GAGE 141251100 is a Class X Minus tolerance pin gage used to verify hole diameters, check bore sizes, and calibrate measuring equipment to a known standard. Machined from tool steel and finished to a 4 microinch surface finish, this gage pin measures 0.511 inches in diameter and 2 inches in length. The minus tolerance designation means the gage is manufactured to a tolerance of -0.00004 inches from nominal, placing the pin just under the nominal diameter. Each unit ships with a Certificate of Accuracy traceable to NIST, making it suitable for quality control environments where documentation is required.

Class X Minus pin gages are used in machine shops, metrology labs, and manufacturing facilities to verify drilled, reamed, or bored hole dimensions with high precision. This particular pin is sized for applications requiring confirmation of a 0.511-inch diameter feature. It is handled and used by machinists, quality technicians, and calibration specialists working to dimensional tolerances in both production and inspection settings.

Key Features

• Class X Minus tolerance: -0.00004 inches from nominal for high-precision go/no-go inspection
• 4 microinch surface finish for smooth, accurate contact with the gauged surface
• Tool steel construction for hardness and dimensional stability under repeated use
• Includes Certificate of Accuracy with NIST traceability for documented calibration compliance
• Compact 2-inch length suits bench inspection and handheld use

Compatibility

Designed for use as a precision dimensional reference in applications requiring calibration of measuring equipment or direct gaging of parts with a nominal 0.511-inch diameter feature.

Installation Notes

Pin gages are handled by quality technicians and metrologists and require no permanent installation. Keep the gage clean and lightly oiled when stored to prevent corrosion on the tool steel surface. Never force a pin gage into a feature; if resistance is encountered, the hole is undersize. Store in a protective case away from temperature extremes to maintain dimensional stability.
