Vermont Gage 111156300 Class Zz Plus Plug Gage 0.563 in

Product Description

The VERMONT GAGE 111156300 is a Class ZZ Plus plug gage designed for precision go inspection of machined bores and holes. It measures a nominal diameter of 0.563 inches with a tight tolerance of 0.0002 inches, making it suitable for high-accuracy dimensional verification tasks. Manufactured from tool steel and finished to a 10 microfinish surface, this gage delivers consistent, reliable readings in shop-floor and inspection-room environments. A Certificate of Accuracy with NIST traceability is included, supporting quality documentation requirements. Machinists, tool-and-die makers, and quality control technicians use this type of gage daily for fast pass-fail bore verification.

This plug gage is suited for go inspection applications across manufacturing, toolroom, and quality assurance environments. It is compatible with inspection workflows that require verification against ASME B89.1 standards. The 111156300 is also used to set and check micrometers, verniers, and other measuring devices where a precision reference of 0.563 inches is needed. Its compact overall length of 2.0 inches makes it easy to handle in tight-clearance inspection scenarios. Applicable in both production and job-shop settings where dimensional conformance must be documented.

Key Features

• Class ZZ Plus tolerance grade for reliable go inspection of 0.563 inch bores
• 0.0002 inch tolerance for high-precision dimensional verification
• 10 microfinish surface for consistent gage-to-workpiece contact
• Tool steel construction for durability in production and toolroom use
• Meets ASME B89.1 standards for dimensional gaging
• Includes Certificate of Accuracy with NIST traceability for quality documentation

Compatibility

Designed for go inspection of machined bores and holes at 0.563 inches nominal diameter, and for setting and checking micrometers, verniers, and other measuring devices requiring a precision reference at that diameter.

Installation Notes

This gage is handled and used by machinists, quality technicians, and toolroom personnel. Before use, ensure the gage and workpiece are clean and at a stable ambient temperature, as thermal variation affects precision measurements. Do not force the gage into a bore; apply only light, consistent hand pressure to avoid gage or workpiece damage. Store in the provided case or a clean, protected environment to maintain surface finish and calibration integrity.
