Vermont Gage 111154800 Class Zz Plus Plug Gage 0.548 in

Product Description

The VERMONT GAGE 111154800 is a Class ZZ Plus plug gage designed for precision dimensional inspection in tool rooms, calibration labs, and production environments. Machined from tool steel to a 0.548-inch nominal diameter with a tolerance of 0.0002 inches and a 10 microinch surface finish, this gage delivers consistent, reliable measurement performance. At 2.0 inches overall length, it is a compact, hand-held instrument suited for verifying bore and hole dimensions against accepted go/no-go acceptance criteria. Each unit ships with a Certificate of Accuracy backed by NIST traceability, meeting ASME B89.1 standards.

This plug gage is used in go inspection applications, including setting and verifying micrometers, verniers, and other precision measuring devices. It is appropriate for use in precision machining, manufacturing quality control, and metrology lab environments. Machinists, quality technicians, and calibration specialists rely on Class ZZ Plus gages for routine production inspection and instrument calibration setups where certified dimensional accuracy is required.

• 10 microinch surface finish for consistent, repeatable gage contact
• Tool steel construction for wear resistance and dimensional stability
• 2.0-inch overall length for easy hand-held use in bench and floor applications
• Meets ASME B89.1 standards for dimensional gaging
• Includes Certificate of Accuracy with NIST traceability

Compatibility

Designed as a go inspection plug gage for use with micrometers, verniers, and other precision measuring devices requiring a certified 0.548-inch reference standard.

Installation Notes

Plug gages are handled and used by quality technicians and calibration professionals. Keep the gage clean and lightly oiled when not in use to prevent corrosion of the tool steel surface. Do not force the gage into a bore; light, consistent hand pressure is appropriate for accurate go inspection results. Store in the provided case or a protected rack to preserve the surface finish and dimensional integrity.
