Vermont Gage 111108600 Class Zz Plus Plug Gage 0.086 in

Product Description

The VERMONT GAGE 111108600 is a Class ZZ Plus plug gage machined from tool steel, designed to perform go inspection on drilled, reamed, or bored holes with a nominal diameter of 0.086 inches. The gage holds a tolerance of 0.0002 inches and carries a 10 microfinish surface finish, ensuring precise, repeatable measurement at the bench or on the shop floor. Overall length is 2 inches. A Certificate of Accuracy with NIST traceability is included, meeting ASME B89.1 standards. Machinists, quality technicians, and metrologists use this gage to verify whether a feature falls within acceptable dimensional limits.

This plug gage is suited for go inspection of small-diameter holes in production and inspection environments, including machine shops, toolrooms, and quality labs. It is also used to set and verify micrometers, verniers, and other measuring devices requiring a traceable reference standard. The small 0.086-inch diameter makes it appropriate for precision work on tight-tolerance components such as instrument parts, small fastener holes, and hydraulic or pneumatic porting. Both production floor inspectors and metrology professionals rely on this class of gage for attribute-style pass-fail inspection.

Key Features

• Class ZZ Plus tolerance: 0.0002 inches for reliable go inspection
• 10 microfinish surface for consistent, low-wear contact
• Tool steel construction for durability in repeated use
• Meets ASME B89.1 dimensional gage standard
• Includes Certificate of Accuracy with NIST traceability
• Overall length of 2 inches for easy handling on small-bore work

Compatibility

Designed as an OEM-style go plug gage for inspecting holes with a nominal diameter of 0.086 inches. Compatible with standard gage handle systems and suitable for use as a reference standard when setting micrometers, verniers, and other precision measuring devices.

Installation Notes

Plug gages are handled and used by quality technicians and machinists; no permanent installation is required. Store the gage in its protective case when not in use to prevent damage to the lapped surface. Do not force the gage into a hole under inspection, as this can damage both the gage and the workpiece. Clean the gage and the hole to be measured before use to ensure accurate results.
