Vermont Gage 111114500 Class Zz Plus Plug Gage 0.145 in

Product Description

The VERMONT GAGE 111114500 is a Class ZZ Plus plug gage machined from tool steel for precision bore and hole inspection. It measures 0.145 inches in diameter with a tolerance of 0.0002 inches, making it suitable for Go inspection work where tight dimensional verification is required. The gage carries a 10 microfinish surface finish and ships with a Certificate of Accuracy traceable to NIST, confirming it meets ASME B89.1 standards. Machinists, quality technicians, and tool room personnel use this type of gage to verify that a drilled, reamed, or bored hole falls within its specified acceptance limit. Overall length is 2.0 inches.

This plug gage is suited for use in inspection stations, machine shops, and production environments where repeatable dimensional verification is critical. Primary applications include Go inspection of precision bores, calibration and verification setups with set micrometers, verniers, and other measuring devices. Its compact 0.145-inch diameter makes it appropriate for small-bore work common in precision part manufacturing, tool and die, and quality control operations.

Key Features

• Class ZZ Plus tolerance rating with 0.0002 inch tolerance for precise Go inspection
• Tool steel construction for wear resistance and dimensional stability
• 10 microfinish surface for consistent gage-to-bore contact
• Includes Certificate of Accuracy with NIST traceability
• Complies with ASME B89.1 dimensional standard
• Compact 2.0 inch overall length suited for bench and in-process inspection

Compatibility

Designed for Go inspection of precision bores and for use with set micrometers, verniers, and other measuring devices requiring a Class ZZ Plus reference standard at 0.145 inches diameter.

Installation Notes

Plug gages of this type are handled by quality technicians and machinists in controlled inspection environments. Keep the gage clean and lightly oiled with instrument-grade oil when not in use to prevent corrosion and protect the finish. Do not force the gage into a bore; proper Go inspection relies on hand pressure only. Store in a protective case away from temperature extremes to maintain dimensional accuracy.
