Vermont Gage 111148200 Class Zz Plus Plug Gage 0.482 in

Product Description

The VERMONT GAGE 111148200 is a Class ZZ Plus plug gage used to verify bore and hole diameters to a high degree of accuracy. This go-style inspection gage measures 0.482 inches in diameter with a tolerance of 0.0002 inches and a 10 microfinish surface finish. The overall length is 2.0 inches. Manufactured from tool steel, the 111148200 delivers the dimensional stability required for repeated use in production and inspection environments. Each unit ships with a Certificate of Accuracy traceable to NIST, making it suitable for use in documented quality systems. Machinists, quality control technicians, and metrology professionals install and use this gage in machine shops, manufacturing facilities, and inspection labs.

This plug gage is designed for go inspection applications, confirming that a hole or bore meets its minimum acceptable size. It is also used to calibrate and verify set micrometers, verniers, and other precision measuring devices. The 0.482-inch diameter makes it applicable to close-tolerance machining work where hole acceptance criteria must be confirmed before assembly. Typical users include CNC machinists, QC inspectors, and tool and die technicians working to ASME B89.1 dimensional standards in both job shop and high-volume production settings.

• 10 microfinish surface finish for smooth, repeatable gage contact
• Tool steel construction provides hardness and dimensional stability under repeated use
• Meets ASME B89.1 standards for dimensional gaging
• Includes Certificate of Accuracy with NIST traceability for documented quality systems
• Overall length of 2.0 inches for easy hand-held use

Compatibility

Designed for use as a go inspection gage for holes and bores at 0.482 inches diameter. Also compatible with set micrometer, vernier, and other precision measuring device calibration and verification workflows per ASME B89.1.

Installation Notes

Plug gages are handled and used by quality control technicians and machinists — no permanent installation is required. Before use, clean the gage and the bore being inspected to remove chips, coolant, and debris that could affect the reading or damage the gage surface. Do not force a go gage into a bore; if it does not pass under light hand pressure, the bore is undersized. Store the gage in its case away from other tooling to prevent surface damage and maintain calibration integrity.
