Vermont Gage 111192400 Class Zz Plus Plug Gage 0.924 in

Product Description

The VERMONT GAGE 111192400 is a Class ZZ Plus plug gage used to verify bore and hole dimensions in precision inspection work. It measures a nominal diameter of 0.924 inches with a tolerance of 0.0002 inches, making it suitable for go-type inspection checks where tight dimensional control is required. The gage is machined from tool steel and finished to a 10 microinch surface finish. A Certificate of Accuracy with NIST traceability is included, supporting documented quality control processes. Machinists, toolroom inspectors, and quality technicians use this type of gage to confirm that drilled, reamed, or bored features meet specified limits.

This plug gage is designed for go inspection applications and is compatible with use alongside set micrometers, verniers, and other measuring devices in a calibrated inspection environment. It is commonly used in manufacturing, toolroom, and metrology lab settings where bore acceptance criteria must be confirmed against a reference standard. The 2.0-inch overall length provides a comfortable, stable grip during single-handed insertion checks on production or inspection fixtures.

Key Features

• Class ZZ Plus tolerance grade with 0.0002 inch tolerance for reliable go-type inspection
• 0.924 inch nominal measurement diameter
• 10 microinch surface finish for consistent, repeatable contact with bore surfaces
• Tool steel construction for wear resistance in production inspection environments
• Certificate of Accuracy with NIST traceability included for audit and calibration records
• Conforms to ASME B89.1 standards

Compatibility

Designed for go inspection use with set micrometers, verniers, and other precision measuring devices as stated by the manufacturer. Suitable for inspecting 0.924 inch nominal bores in standard toolroom and production inspection applications.

Installation Notes

Plug gages are handled and used by machinists, quality technicians, and calibration lab personnel. Clean the gage and the bore surface before use to prevent debris from affecting the reading or damaging the gage surface. Store the gage in its protective case when not in use to preserve the surface finish and dimensional integrity. Periodic recalibration against a NIST-traceable standard is recommended to maintain measurement accuracy over time.
