Vermont Gage 111143500 Class Zz Plus Plug Gage 0.435 in

Product Description

The VERMONT GAGE 111143500 is a Class ZZ Plus plug gage machined to a 0.435-inch nominal diameter with a tolerance of 0.0002 inches. It is designed for go-type dimensional inspection of bored holes, machined bores, and precision-fit features across manufacturing and metrology environments. The gage measures 2.0 inches in overall length and is manufactured from tool steel with a 10 microfinish surface treatment. Each unit ships with a Certificate of Accuracy with NIST traceability, meeting ASME B89.1 standards. Machinists, tool room technicians, and quality-control inspectors use this type of gage to verify that a feature falls within specified limits quickly and reliably.

This plug gage is suited for go-type inspection on the shop floor or in a quality lab. It is used to verify bore diameters on machined components in production and job-shop settings. The 0.435-inch diameter makes it appropriate for checking holes that must accept fasteners, pins, or mating parts at that nominal size. It is also used to calibrate and set micrometers, verniers, and other measuring devices where a traceable physical reference is required. Applications span general manufacturing, aerospace, automotive, and any precision machining operation where dimensional control is critical.

Key Features

• 0.435-inch nominal diameter with 0.0002-inch Class ZZ Plus tolerance
• 10 microfinish surface on the gage pin for accurate, repeatable seating
• Tool steel construction for hardness and wear resistance in production use
• Meets ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST traceability for audit and calibration records
• 2.0-inch overall length provides a comfortable, stable grip during inspection

Compatibility

Designed as a go-type plug gage reference for setting and verifying micrometers, verniers, and other measuring devices requiring a 0.435-inch traceable dimensional standard in precision inspection applications.

Installation Notes

Plug gages are handled and used by quality technicians and machinists; no installation in the traditional sense applies. Store the gage in its protective case when not in use to prevent surface damage and corrosion. Clean the gage pin and the bore being inspected before use to remove chips, coolant, and debris that could affect the measurement reading. Do not force the gage into an undersized bore, as this will damage the precision-ground surface and compromise gage accuracy.
