Vermont Gage 112115820 Class Zz Plus Plug Gage 15.82mm

Product Description

The VERMONT GAGE 112115820 is a Class ZZ Plus plug gage designed for dimensional inspection of bored holes and machined features at a nominal diameter of 15.82 mm. Made from tool steel with a 10 micro-inch surface finish, this gage delivers a tolerance of 0.005 mm, meeting ASME B89.1 standards for precision measurement. It ships with a Certificate of Accuracy traceable to NIST, giving quality departments documented verification at the point of use. Machinists, quality technicians, and metrology lab personnel rely on this style of gage for fast, reliable go-inspection checks on production and repair work.

This plug gage is suited for go inspection applications across manufacturing, machine shops, and quality control environments. It is used with micrometers, vernier calipers, and other measuring devices to verify that a bored or reamed hole meets minimum diameter requirements. The 15.82 mm nominal diameter targets precision-machined components where tight tolerances are critical. Its compact overall length of 2.0000 inches makes it easy to handle in both bench-top and in-process inspection scenarios.

Key Features

• Class ZZ Plus tolerance grade with 0.005 mm tolerance per ASME B89.1
• Tool steel construction for durability and wear resistance in repeated use
• 10 micro-inch surface finish for accurate, consistent contact measurements
• Includes Certificate of Accuracy with NIST traceability for documentation compliance
• Designed for go inspection use with micrometers, verniers, and other measuring devices
• Compact 2.0000-inch overall length for easy handling in bench or in-process inspection

Compatibility

Designed for go inspection use with micrometers, vernier calipers, and other precision measuring devices requiring a 15.82 mm diameter reference standard.

Installation Notes

Plug gages are handled and used by quality technicians and machinists familiar with ASME B89.1 inspection practices. Keep the gage surface clean and lightly oiled when not in use to prevent corrosion on the tool steel body. Do not force the gage into a bore; excessive force will cause premature wear and compromise measurement accuracy. Store in a protective case away from temperature extremes to maintain dimensional stability.
