Vermont Gage 112100560 Class Zz Plus Plug Gage 0.56 Mm

Product Description

The VERMONT GAGE 112100560 is a Class ZZ Plus precision plug gage designed to verify minimum acceptable hole dimensions in go-inspection applications. Machined from tool steel and finished to a 10 microfinish surface, this gage delivers reliable dimensional verification at 0.56 mm diameter with a tolerance of 0.00508 mm. At 2.0 inches overall length and weighing just 0.01 pounds, it is a compact, handheld instrument suited for use on the shop floor or in quality-control environments. Each unit ships with a Certificate of Accuracy with NIST traceability, satisfying documentation requirements for AS9100, ISO 9001, and similar quality management systems.

This plug gage is used in go-inspection routines to confirm that a drilled, reamed, or otherwise formed hole meets its minimum size specification. It is appropriate for use alongside set micrometers, verniers, and other precision measuring devices as part of a complete dimensional inspection program. Typical users include machinists, quality technicians, and tool-and-die professionals working in precision manufacturing environments where tight hole tolerances must be verified to ASME B89.1 standards.

Key Features

• Class ZZ Plus tolerance grade: 0.00508 mm tolerance for high-accuracy go-inspection work
• 10 microfinish surface for repeatable, low-wear contact with the gauged bore
• Tool steel construction for durability under regular shop use
• Includes Certificate of Accuracy with NIST traceability for quality system documentation
• Conforms to ASME B89.1 standards for plug gage dimensional requirements
• Compact 2.0-inch overall length for easy single-hand operation

Compatibility

Designed for use in go-inspection applications and compatible with set micrometers, verniers, and other precision measuring devices per ASME B89.1 requirements.

Installation Notes

Plug gages are handled and used by quality technicians and machinists - no installation in the traditional sense applies, but proper handling practice is critical. Store the gage in its case when not in use to prevent nicks or surface contamination that could affect accuracy. Never force the gage into a bore; go gages should pass under their own weight or light hand pressure only. Clean the gage and bore contact surfaces before each use, and re-verify calibration status against the included NIST-traceable certificate at intervals required by your quality management system.
