Vermont Gage 112105400 Class Zz Plus Plug Gage 5.4 Mm

Product Description

The VERMONT GAGE 112105400 is a Class ZZ Plus plug gage manufactured from tool steel for dimensional inspection of bores and holes. It measures 5.4 mm in diameter with a tolerance of 0.00508 mm and features a 10 microfinish surface finish. Designed for go inspection applications, this gage provides a reliable, repeatable method to verify that a machined hole falls within acceptable dimensional limits. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting quality system documentation requirements. Licensed metrology technicians, machinists, and quality control inspectors are the typical end users.

This plug gage is suited for use in manufacturing, machining, and precision inspection environments where tight bore tolerances must be verified. It is appropriate for both production floor and inspection room use. Beyond go inspection, it is compatible with setup and calibration of micrometers, verniers, and other measuring devices. The compact overall length of 2 inches makes it easy to handle at a workbench or on the shop floor. It is commonly used in aerospace, automotive, and general precision manufacturing where ASME B89.1 compliance is required.

Key Features

• Class ZZ Plus tolerance grade per ASME B89.1 for go inspection reliability
• 5.4 mm diameter with 0.00508 mm tolerance for tight bore verification
• 10 microfinish surface for consistent, accurate contact with the workpiece
• Tool steel construction provides durability and wear resistance in production environments
• Includes Certificate of Accuracy with NIST traceability for quality system compliance
• Compatible with micrometers, verniers, and other precision measuring devices for setup and calibration

Compatibility

Designed for go inspection of 5.4 mm diameter bores and for use as a reference standard with micrometers, verniers, and other precision measuring devices per ASME B89.1.

Installation Notes

Handle plug gages with clean, dry hands or lint-free gloves to prevent contamination and corrosion on the precision surface. Before use, verify the gage is clean and free of burrs or debris that could affect the measurement reading. Store the gage in its protective case when not in use to maintain the calibrated surface finish. Periodic recalibration by a qualified metrology lab is recommended to maintain NIST-traceable accuracy over time.
