Vermont Gage 112117360 Class Zz Plus Plug Gage 17.36mm

Product Description

The VERMONT GAGE 112117360 is a Class ZZ Plus cylindrical plug gage designed for go inspection of bored, reamed, and drilled holes with a nominal diameter of 17.36 mm. Manufactured from tool steel with a 10 microfinish surface coating, this gage delivers a tolerance of 0.00508 mm, meeting the accuracy requirements of ASME B89.1. Every unit ships with a Certificate of Accuracy traceable to NIST. It is used by machinists, quality technicians, and metrology professionals to verify that a workpiece hole falls within the specified acceptance limit during in-process or final inspection.

This plug gage is suited for use in machine shops, tool rooms, and quality control labs handling precision machined components. It functions as a go member to confirm that a hole is large enough to accept the mating part or fastener. The 17.36 mm diameter and tight Class ZZ Plus tolerance make it appropriate for applications where standard Class ZZ tolerances are insufficient. It is also referenced when setting and verifying micrometers, verniers, and other comparative measuring devices.

Key Features

• Class ZZ Plus tolerance of 0.00508 mm for tight-tolerance go inspection
• 17.36 mm nominal diameter with 10 microfinish surface coating
• Tool steel construction for hardness and dimensional stability
• Meets ASME B89.1 standard for plain plug gages
• Includes Certificate of Accuracy with NIST traceability
• Compatible with go inspection use and as a reference standard for measuring instruments

Compatibility

Designed for go inspection of holes with a 17.36 mm nominal diameter. Also suitable for setting and verifying micrometers, verniers, and other measuring devices requiring a traceable reference standard at this diameter.

Installation Notes

Plug gages are handled and stored by metrology technicians and quality control personnel, not installed in the conventional sense. Always clean the gage and workpiece bore before use to prevent false readings or surface damage. Do not force the gage through an undersized hole, as this can damage the gage land or alter its calibration. Store in a protective case away from temperature extremes to maintain dimensional integrity.
