Vermont Gage 112401530 Class Zz Minus Plug Pin Gage 1.53 Mm

Product Description

The VERMONT GAGE 112401530 is a Class ZZ Minus plug pin gage machined to a 1.53 mm diameter with a tolerance of 0.00508 mm. It is used to perform NoGo dimensional inspection checks on bores, holes, and precision-machined features. The gage is manufactured from steel with a 10 microfinish surface coating and has an overall length of 2 inches. Each unit ships with a Certificate of Accuracy traceable to NIST standards, making it suitable for quality-control environments that require documented calibration traceability. Metrologists, machinist inspectors, and toolroom technicians are the primary users of this instrument.

This pin gage is designed for NoGo inspection applications where confirming a hole or bore does not exceed its maximum allowable size is required. It is also used alongside set micrometers, verniers, and other precision measuring devices as a reference standard or setup aid. Typical use environments include machine shops, manufacturing quality-control floors, tool rooms, and metrology labs performing incoming or in-process inspection of tight-tolerance parts.

Key Features

• Class ZZ Minus tolerance classification: 0.00508 mm tolerance for high-precision NoGo gauging
• 1.53 mm diameter for small-bore and precision-hole inspection
• Steel construction with 10 microfinish surface coating for durability and accuracy
• Overall length of 2 inches for comfortable hand-held use
• Includes Certificate of Accuracy with NIST traceability for documented calibration records
• Compatible with set micrometers, verniers, and other precision measuring instruments as a reference

Compatibility

Designed for use in NoGo inspection applications and as a reference standard with set micrometers, verniers, and other precision measuring devices.

Installation Notes

Pin gages are handled and used by metrologists, quality inspectors, and precision machinist technicians. Always clean the gage and the bore or reference surface before use to prevent debris from affecting the measurement. Store the gage in its protective case when not in use to preserve the surface finish and dimensional integrity. Do not force the gage into a bore; if resistance is encountered, the feature is at or below the NoGo limit.
