Vermont Gage 111315650 Class Zz Plus Plug Gage 0.1565 in

Product Description

The VERMONT GAGE 111315650 is a Class ZZ Plus plug gage designed to perform go-type dimensional inspection on holes and bores with a nominal diameter of 0.1565 inches. Machined from tool steel and finished to a 10 microfinish surface, this gage provides reliable, repeatable measurement in production and quality-control environments. Overall length is 2.0000 inches. The tolerance is 0.0002 inches, meeting ASME B89.1 standards. Each unit ships with a Certificate of Accuracy traceable to NIST, making it suitable for applications where documented traceability is required by quality management systems.

This plug gage is used in machine shops, manufacturing facilities, and inspection labs wherever precise bore or hole verification is required. Typical applications include go inspection of drilled, reamed, or punched holes, as well as calibration and verification of set micrometers, verniers, and other measuring devices. It is sized for work on small-diameter features common in precision machining, tooling, and instrument manufacturing. Machinists, quality technicians, and metrology professionals are the primary users of this type of gage.

Key Features

• Class ZZ Plus tolerance grade at 0.0002 inches for precise go inspection
• Tool steel construction for durability and wear resistance in production use
• 10 microfinish surface for consistent, low-friction gage contact
• Meets ASME B89.1 dimensional standards
• Includes Certificate of Accuracy with NIST traceability for quality documentation
• Compact 2.0000-inch overall length suits tight-access inspection scenarios

Compatibility

Designed as an OEM-style inspection gage for use in go-inspection setups and as a reference standard for setting micrometers, verniers, and other precision measuring devices requiring a 0.1565-inch diameter reference.

Installation Notes

This gage is handled and used by quality technicians and machinists following standard metrology practices. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel surface. Never force the gage into a feature; apply only light hand pressure to avoid wear or damage to the gage or the workpiece. Store in a protective case away from temperature extremes to maintain dimensional integrity and calibration validity.
