Vermont Gage 112108160 Class Zz Plus Plug Gage 8.16mm

Product Description

The VERMONT GAGE 112108160 is a Class ZZ Plus cylindrical plug gage with an 8.16 mm diameter, designed for Go inspection of bored, drilled, reamed, or broached holes. Built from tool steel with a 10 microfinish surface, it delivers dimensional verification at a tolerance of 0.005 mm, making it suitable for quality control environments that require traceable, repeatable measurement results. The gage ships with a Certificate of Accuracy backed by NIST traceability, supporting documentation requirements for ISO and ASME-compliant inspection programs. Overall length is 2.0000 inches. At 0.05 pounds, the gage is lightweight and easy to handle during bench or floor inspection tasks.

This plug gage is used in production and inspection settings where hole diameter conformance must be verified before assembly. Typical applications include setting micrometers, verniers, and other measuring devices, as well as Go inspection of machined components in manufacturing facilities. Quality technicians, machinists, and metrology professionals use this gage at inspection stations, CMM support benches, and tool crib setups. It is appropriate for both low-volume job shop environments and higher-throughput production lines where dimensional accuracy of 8.16 mm bores is a process control requirement.

Key Features

• 8.16 mm Go inspection diameter with 0.005 mm tolerance for precise hole conformance checking
• 10 microfinish surface coating for consistent, low-wear contact during repeated use
• Tool steel construction provides durability and dimensional stability over service life
• Includes Certificate of Accuracy with NIST traceability for documented inspection programs
• Meets ASME B89.1 standards for plain plug gage dimensional requirements
• 2.0000 inch overall length fits standard handle configurations used in bench inspection

Compatibility

Designed for Go inspection of 8.16 mm diameter holes and for use as a setting standard with micrometers, verniers, and other precision measuring devices in accordance with ASME B89.1.

Installation Notes

Plug gages are handled and used by quality technicians and machinists - no power tools or utility shutoffs are required. Store the gage in its case and apply a light coat of protective oil when not in use to prevent corrosion of the tool steel. Do not force the gage into an undersized hole, as this can damage both the gage and the workpiece. Verify gage calibration status against the Certificate of Accuracy before use in a controlled inspection process.
