Vermont Gage 111216100 Class Zz Minus Plug Pin Gage 0.1610 in

Product Description

The VERMONT GAGE 111216100 is a Class ZZ Minus plug pin gage machined from steel and used to perform NoGo inspection checks on bored, drilled, or reamed holes. It measures 0.1610 inches in diameter with a tolerance of 0.0002 inches, making it suitable for verifying that a hole does not exceed its maximum allowable size. At 2 inches in overall length, the gage is sized for handheld use in production or inspection environments. Each unit ships with a Certificate of Accuracy that carries NIST traceability, satisfying quality-system documentation requirements. Machinists, quality control technicians, and tool and die professionals are the primary users of this type of gage.

This plug pin gage is designed for NoGo inspection work and can also be used to set micrometers, verniers, and other measuring devices requiring a known reference diameter. It is appropriate for incoming inspection, in-process checks, and final inspection on machined components in both job-shop and production-floor settings. The 10 microfinish surface coating supports accurate, repeatable contact with the work surface and helps resist wear during routine gauging operations.

Key Features

• Class ZZ Minus tolerance grade at 0.0002 inches for NoGo inspection applications
• 0.1610 inch diameter for checking maximum hole-size limits
• Steel construction with 10 microfinish surface for wear resistance and measurement consistency
• 2 inch overall length suits handheld inspection use
• Includes Certificate of Accuracy with NIST traceability for quality-system compliance
• Compatible with use as a setting reference for micrometers, verniers, and other measuring devices

Compatibility

Designed for use as a NoGo plug gage in standard go/no-go inspection setups and as a setting reference for micrometers, verniers, and comparable measuring instruments requiring a 0.1610 inch diameter reference.

Installation Notes

Plug pin gages are handled and used by quality control technicians and machinists — no power source or mechanical installation is required. Store the gage in its protective case when not in use to prevent surface damage that could affect measurement accuracy. Clean the gage and the part being inspected before use to remove chips, oil, or debris that can introduce error. Do not force the gage into an undersized hole, as this can cause galling and alter the gage diameter.
