Vermont Gage 112100520 Class Zz Plus Plug Gage 0.52mm

Product Description

The VERMONT GAGE 112100520 is a Class ZZ Plus plug gage designed for precise go inspection of small-diameter bores and holes. Turned from tool steel, this pin gage measures 0.52 mm in diameter with a tolerance of 0.00508 mm, making it suitable for high-accuracy dimensional verification in toolrooms and quality-control environments. A 10 microfinish surface provides consistent contact during inspection. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting ASME B89.1 standards. Machinists, quality technicians, and metrology professionals use this gage as part of systematic go inspection routines.

This plug gage is used in go inspection applications to verify that a feature meets its minimum size requirement. It is well suited for checking precision bores on machined components, setting micrometers, and calibrating verniers and other measuring devices. The 0.52 mm diameter targets fine-tolerance features common in medical device manufacturing, electronics, and precision mechanical assemblies. Its compact form factor suits both bench and floor inspection stations.

Key Features

• Class ZZ Plus tolerance classification for reliable go inspection
• 0.52 mm diameter with 0.00508 mm tolerance for tight dimensional control
• 10 microfinish surface for consistent, repeatable gauge contact
• Tool steel construction for durability and wear resistance
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 standards

Compatibility

Designed for use with go inspection setups and compatible with standard gage handle systems. Suitable for setting micrometers, verniers, and other measuring devices requiring a certified reference pin in the 0.52 mm diameter range.

Installation Notes

Pin gages should be handled with clean, dry hands or lint-free gloves to prevent corrosion from skin contact. Store in the provided case or a clean, dry environment when not in use. No power source is required; however, the gage should be inspected for wear or damage before each use. Calibration and inspection work should be performed in accordance with applicable quality system requirements and ASME B89.1 guidelines.
