Vermont Gage 112119620 Class Zz Plus Plug Gage 19.62 Mm

Product Description

The VERMONT GAGE 112119620 is a Class ZZ Plus plug gage machined from tool steel for dimensional go inspection of bored holes and machined bores at 19.62 mm nominal diameter. It carries a tolerance of 0.00508 mm, making it suitable for high-precision verification work in tool rooms, production floors, and quality labs. The gage ships with a Certificate of Accuracy traceable to NIST, giving calibration teams the documentation required for ISO and AS9100-compliant inspection programs. Overall length is 2.0000 inches. Machinists, quality technicians, and metrologists are the typical end users.

This plug gage is used wherever a reliable go-type attribute check is needed on a 19.62 mm bore. Typical applications include verifying hole size after drilling, reaming, or boring operations on production parts. It is also suited for setting and calibrating micrometers, verniers, bore gages, and other variable measuring devices to a traceable reference. The gage is appropriate for both job-shop and high-volume manufacturing environments where repeatable attribute inspection is required.

Key Features

• Tool steel construction for durability and wear resistance in production use
• 10 Micro surface finish coating for consistent gage contact
• Certificate of Accuracy included with full NIST traceability
• Conforms to ASME B89.1 standard
• Suitable for setting micrometers, verniers, and other measuring devices

Compatibility

Designed as a go-type attribute plug gage for 19.62 mm nominal diameter bores in accordance with ASME B89.1. Compatible with standard gage handle sets used in production and quality inspection applications.

Installation Notes

Plug gages are handled and used by quality technicians and machinists and do not require power or mechanical installation. Store the gage in its protective case when not in use to prevent nicks or corrosion that would affect accuracy. Clean the gage and the bore being inspected before use to remove chips, coolant, and debris. Never force a go gage into an undersized bore, as this will damage the gage surface and void traceability.
