Vermont Gage 111108700 Class Zz Plus Plug Gage 0.087 in

Product Description

The VERMONT GAGE 111108700 is a Class ZZ Plus plug gage machined from tool steel for precise go-type inspection of bored holes, drilled passages, and other internal features. The gage measures a nominal diameter of 0.087 inches with a tolerance of 0.0002 inches, giving machinists and quality technicians a reliable reference for verifying that a workpiece opening meets minimum acceptable size. A 10 microfinish surface treatment on the gaging member reduces wear and ensures consistent contact with the workpiece. Each unit ships with a Certificate of Accuracy traceable to NIST, satisfying documentation requirements for ISO and AS9100-registered facilities. Licensed metrology technicians and precision machinists are the primary users.

This plug gage is suited for go inspection tasks in production machining, tool rooms, and quality control departments. It is also used as a reference standard when setting micrometers, verniers, and other indicating or measuring devices to a known diameter. At 0.087 inches, the gage addresses small-bore work common in hydraulic fittings, medical device components, electronic hardware, and precision mechanical assemblies. The 2.0-inch overall length provides adequate handling clearance in most bench inspection setups. Conformance to ASME B89.1 makes it acceptable under standard metrology program requirements.

Key Features

• Class ZZ Plus tolerance of 0.0002 inches for go-inspection accuracy
• 10 microfinish surface on gaging member for reduced wear and consistent contact
• Tool steel construction for long service life under repeated use
• Certificate of Accuracy included with full NIST traceability
• Meets ASME B89.1 dimensional gage standards
• Overall length of 2.0 inches for comfortable bench handling

Compatibility

Designed for go inspection of features at 0.087 inches nominal diameter and for use as a setting reference with micrometers, verniers, and other measuring devices as stated in the product application data.

Installation Notes

Plug gages are handled and used by metrology technicians and machinists in inspection environments rather than installed in mechanical systems. Store the gage in its protective case when not in use to prevent nicks and corrosion. Clean the gaging member with a lint-free cloth before each use and apply a light coat of rust-preventive oil for storage. Do not force the gage into an undersized hole, as this will damage the lapped surface finish and invalidate the calibration certificate.
