Vermont Gage 112115520 Class Zz Plus Plug Gage 15.52mm

Product Description

The VERMONT GAGE 112115520 is a Class ZZ Plus plug gage designed for precise bore and hole inspection in production and quality control environments. Manufactured from tool steel with a 10 micro-inch finish, this gage checks whether a feature falls within acceptable dimensional limits. It carries a 0.005 mm (0.00508 mm actual) tolerance and is sized at 15.52 mm in diameter. A Certificate of Accuracy with NIST traceability is included, making it suitable for documented inspection processes. Machinists, quality technicians, and metrology professionals install and use this gage during go inspection procedures on the shop floor or in the inspection lab.

This plug gage is used for go inspection of bored, drilled, reamed, or otherwise machined holes nominally sized at 15.52 mm. It is also suited for setting and verifying micrometers, verniers, and other measuring devices. Typical applications include production-line attribute inspection in manufacturing environments where hole diameter conformance must be confirmed quickly and reliably. The overall length of 2.0000 inches makes it compatible with standard gage handle systems used in light to medium industrial inspection work.

Key Features

• Class ZZ Plus tolerance of 0.005 mm for accurate go inspection
• Tool steel construction with 10 micro-inch surface finish for durability and wear resistance
• 15.52 mm nominal diameter for direct hole conformance checking
• Certificate of Accuracy with NIST traceability included for documented quality systems
• Conforms to ASME B89.1 standards
• Overall length of 2.0000 inches compatible with standard gage handles

Compatibility

Designed for use with standard gage handle systems for go inspection of 15.52 mm diameter features. Also suitable for setting micrometers, verniers, and other measuring devices as specified by the manufacturer.

Installation Notes

Plug gages are handled and used by quality technicians and machinists trained in precision measurement practices. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel surface. Do not force the gage into a feature; if resistance is felt, the hole is undersized and should be returned for rework. Store the gage in its case away from temperature extremes to preserve dimensional stability and calibration integrity.
