Vermont Gage 112408130 Class Zz Minus Plug Pin Gage 8.13mm

Product Description

The VERMONT GAGE 112408130 is a Class ZZ Minus plug pin gage used to perform NoGo dimensional inspection on bored holes, machined bores, and precision-fit openings. It measures 8.13 mm in diameter with a tolerance of 0.00508 mm, making it suited for applications where tight dimensional control is required. The gage is manufactured from steel with a 10 microfinish surface coating for consistent contact and wear resistance. Each unit ships with a Certificate of Accuracy carrying NIST traceability, which satisfies documentation requirements in quality management systems. Machinists, toolroom technicians, and quality control inspectors are the primary users of this type of gage.

This pin gage is designed for NoGo inspection work, where the gage must not pass through an acceptable hole. It is also suitable for setting micrometers, verniers, and other comparative measuring devices. At 2 inches overall length, the 112408130 is compact enough for use at a bench or inline in a production environment. Typical applications include incoming inspection, in-process checks, and final inspection of machined components in manufacturing, toolroom, and metrology lab settings.

Key Features

• Class ZZ Minus tolerance designation: 0.00508 mm tolerance for NoGo inspection applications
• Steel construction with 10 microfinish surface coating for durability and consistent gage contact
• NIST-traceable Certificate of Accuracy included with each unit for quality documentation compliance
• 8.13 mm measurement diameter with 2-inch overall length for compact bench or production use
• Compatible with micrometer, vernier, and other measuring device setup applications

Compatibility

Designed for NoGo hole inspection and as a setting reference for micrometers, verniers, and other precision measuring devices requiring an 8.13 mm diameter reference standard.

Installation Notes

Pin gages are handled and used by quality technicians, machinists, and metrologists - no mechanical installation is required. Always clean the gage and the workpiece bore before use to prevent debris from affecting measurement results. Store the gage in its protective case when not in use to prevent surface damage to the precision-ground diameter. Do not force the gage into a bore; if resistance is encountered during a NoGo check, the bore is within tolerance and the gage should be withdrawn without applying additional pressure.
