Vermont Gage 112305130 Class Zz Plus Plug Gage 5.13mm

Product Description

The VERMONT GAGE 112305130 is a Class ZZ Plus plug gage manufactured from tool steel and sized to a 5.13 mm diameter. It is used to verify bore and hole dimensions to a tolerance of 0.00508 mm, confirming whether a feature falls within acceptable limits during go inspection. The 10 microfinish surface coating supports accurate, repeatable contact with the workpiece. Each unit ships with a Certificate of Accuracy with NIST Traceability, making it suitable for quality control environments that require documented calibration support. At 2.0 inches overall length, it is sized for bench or in-process inspection use by machinists, quality technicians, and metrology professionals.

This plug gage is intended for go inspection applications across precision machining, manufacturing, and quality assurance settings. It is compatible with standard gage handle systems and is used alongside set micrometers, verniers, and other measuring devices for dimensional verification. The Class ZZ Plus tolerance class meets ASME B89.1 standards, making it appropriate for inspection in both production and toolroom environments where tight dimensional control is required.

Compatibility

Designed for use in go inspection applications with set micrometers, verniers, and other standard measuring devices per the manufacturer specification. Compatible with standard gage handle systems used in toolroom and production inspection setups.

Installation Notes

Plug gages of this type are handled and used by quality technicians and machinists; no power source or shutoff is required for use. Keep the gage clean and lightly oiled when not in use to prevent corrosion of the tool steel body. Do not force the gage into a bore; apply only light, consistent hand pressure to avoid wear or damage to the gage or workpiece. Store in a protective case away from temperature extremes to maintain dimensional stability and calibration integrity.
