Vermont Gage 112122140 Class Zz Plus Plug Gage 22.14mm

Product Description

The VERMONT GAGE 112122140 is a Class ZZ Plus plug gage designed for dimensional inspection of bored holes and machined features at 22.14 mm nominal diameter. Manufactured from tool steel with a 10 micro finish, it holds a tolerance of 0.005 mm, meeting the requirements of ASME B89.1. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting documented quality systems and audit trails. This gage is intended for use by machinists, quality technicians, and metrologists performing go-type attribute inspection in production or calibration environments.

This plug gage is suited for go inspection of precision bored holes, drilled passages, and reamed features in metal components across manufacturing and machining operations. It is compatible with standard gage block comparators, set micrometers, verniers, and other fixed-limit measuring devices used in shop-floor or lab inspection setups. The 22.14 mm diameter makes it applicable to metric-dimensioned workpieces common in general machining, tooling, and OEM component inspection workflows.

Key Features

• Class ZZ Plus tolerance grade per ASME B89.1 for reliable attribute inspection
• 0.005 mm tolerance for accurate go-type dimensional verification
• Tool steel construction for durability in repetitive inspection use
• 10 micro surface finish for consistent gage-to-bore contact
• Includes Certificate of Accuracy with NIST traceability for quality documentation
• Overall length of 2.0000 inches for standard handle compatibility

Compatibility

Designed for use with set micrometers, verniers, and other fixed-limit measuring devices requiring a Class ZZ Plus plug gage reference at 22.14 mm diameter, per ASME B89.1 standards.

Installation Notes

Plug gages should be handled by quality technicians or calibration personnel following your facility's gage control procedures. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel body. Do not force the gage through an undersized feature, as this will damage the gage surface and invalidate readings. Store in its protective case away from heat sources and abrasive materials to maintain calibration integrity.
