Vermont Gage 112102760 Class Zz Plus Plug Gage 2.76mm

Product Description

The VERMONT GAGE 112102760 is a Class ZZ Plus plug gage designed for precision bore and hole inspection in dimensional quality control applications. Machined from tool steel and finished to a 10 microfinish surface, this gage delivers the accuracy required for go inspection tasks. The 2.76 mm diameter with a tolerance of 0.00508 mm makes it suitable for verifying tight-tolerance features on machined components. Each unit ships with a Certificate of Accuracy that carries NIST traceability, confirming compliance with ASME B89.1 standards. Licensed metrologists, quality technicians, and tool room inspectors are the primary users of this instrument.

This plug gage is used wherever precise hole diameter verification is required on the shop floor or in an inspection lab. Typical applications include go inspection of bored, drilled, or reamed holes and setting of micrometers, verniers, and other measuring devices to a known reference. It is appropriate for both production inspection and tool calibration workflows in precision manufacturing environments.

Key Features

• Class ZZ Plus tolerance grade for reliable go inspection of 2.76 mm diameter features
• Tolerance of 0.00508 mm supports tight-tolerance dimensional verification
• 10 microfinish surface for consistent, repeatable gage contact
• Tool steel construction for wear resistance and dimensional stability
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 dimensional gage standards

Compatibility

Designed for use as a go plug gage for 2.76 mm diameter holes and as a setting reference for micrometers, verniers, and other measuring devices where a certified, traceable diameter reference is required.

Installation Notes

Plug gages are handled and used by quality technicians and metrologists — no installation in the traditional mechanical sense applies. Store the gage in a clean, dry environment and allow it to thermally stabilize to the inspection area temperature before use to prevent false readings due to thermal expansion. Clean the gage and the bore being inspected before each use to remove chips, oil, and debris. Never force the gage into a hole; apply light, controlled hand pressure only.
