Vermont Gage 111257600 Class Zz Minus Plug Gage 0.5760 in

Product Description

The VERMONT GAGE 111257600 is a Class ZZ Minus plug pin gage ground to a diameter of 0.5760 inches with a tolerance of 0.0002 inches. At 2 inches in overall length, this steel pin gage is used to check that a hole or bore does not exceed its maximum allowable size — the NoGo function in a standard Go/NoGo inspection routine. Each unit ships with a Certificate of Accuracy carrying NIST traceability, confirming the measurement is referenced to a national standard. Machinists, quality technicians, and inspection personnel use this gage on the shop floor or in the inspection room.

This pin gage is suited for dimensional inspection of machined bores, drilled holes, and precision-fit components where a 0.5760-inch NoGo check is required. It is also used to set and verify micrometers, verniers, and other measuring devices that require a calibrated reference. The Class ZZ tolerance class is appropriate for general-purpose inspection work rather than master or precision laboratory applications. Typical users include machinists performing in-process inspection and quality control technicians conducting final part acceptance checks.

Key Features

• Class ZZ Minus tolerance designation for NoGo inspection applications
• Measurement diameter of 0.5760 inches with a tolerance of 0.0002 inches
• Overall length of 2 inches for easy handling and insertion
• Steel construction for durability and dimensional stability
• 10 micro finish coating for consistent surface quality
• Includes Certificate of Accuracy with NIST traceability

Compatibility

Designed for use as a NoGo plug pin gage in standard Go/NoGo bore inspection setups and as a reference standard for setting micrometers, verniers, and other measuring devices requiring a 0.5760-inch calibrated reference.

Installation Notes

Pin gages are handled by quality technicians and metrologists following standard dimensional inspection procedures. Keep the gage clean and lightly oiled when not in use to prevent corrosion and dimensional drift. Never force the pin into a bore — insertion should rely only on the weight of the gage or light hand pressure. Store in the original case or a padded gage holder to protect the ground surface from nicks and wear.
