Vermont Gage 111152000 Class Zz Plus Plug Gage 0.52 in

Product Description

The VERMONT GAGE 111152000 is a Class ZZ Plus plug gage used to verify bore and hole dimensions in precision machining and quality control environments. Manufactured from tool steel, it measures 0.52 inches in diameter with a tolerance of 0.0002 inches and a surface finish of 10 microinch. The gage is 2.0 inches in overall length and ships with a Certificate of Accuracy with NIST traceability. It is designed for go inspection use, confirming that a feature falls within the acceptable dimensional range. Machinists, quality technicians, and metrologists rely on this class of gage for reliable, repeatable measurement verification.

The 111152000 is suited for go inspection of holes, bores, and other internal features requiring precise dimensional conformance. It is also used to calibrate and set micrometers, verniers, and other measuring devices where a known reference standard is required. Applicable in both job shop and production environments, this gage supports inspection workflows that demand tight tolerances and traceable accuracy documentation. The ASME B89.1 standard governs its manufacturing specifications, making it appropriate for quality systems that require compliance with recognized dimensional metrology standards.

Compatibility

Designed for go inspection of holes and bores at 0.52 inches diameter, and for setting micrometers, verniers, and other measuring devices requiring a traceable reference standard.

Installation Notes

Plug gages are handled and used by quality technicians and machinists; no power source or mechanical installation is required. Store the gage in a clean, dry environment and avoid contact with abrasive surfaces to preserve the 10 microinch finish. Clean the gage and the workpiece bore before use to prevent debris from affecting measurement results or damaging the gage surface. Follow ASME B89.1 guidelines for proper handling, storage, and calibration intervals to maintain traceability.
