Vermont Gage 112300350 Class Zz Plus Plug Gage 0.35 Mm

Product Description

The VERMONT GAGE 112300350 is a Class ZZ Plus plug gage ground to a 0.35 mm diameter with a tolerance of 0.00508 mm and a 10 microfinish surface finish. Made from tool steel, this plug gage is used to verify bore and hole dimensions in precision machined parts. It is designed for go inspection applications and is compatible with use alongside micrometers, verniers, and other measuring devices. Each unit ships with a Certificate of Accuracy that carries full NIST traceability, making it suitable for quality-controlled environments and calibration lab workflows. Machinists, tool-and-die technicians, and quality inspection professionals are the primary users of this gage.

This plug gage fits into light-duty precision inspection work involving very small diameter bores, commonly encountered in medical device manufacturing, electronics assembly, instrument fabrication, and fine-tolerance machining. The 0.35 mm diameter targets extremely small hole features. At an overall length of 2.0000 inches, the gage is easy to handle during bench inspection routines. It is intended for single-unit use and is sold individually, making it straightforward to source as a direct replacement or addition to an existing gage set.

Key Features

• Class ZZ Plus tolerance grade with 0.00508 mm dimensional tolerance for precision go inspection
• 10 microfinish surface finish for consistent, repeatable contact with bore surfaces
• Tool steel construction for wear resistance and dimensional stability
• NIST-traceable Certificate of Accuracy included with each unit
• Conforms to ASME B89.1 standards for plain plug gages
• Overall length of 2.0000 inches for ergonomic bench use

Compatibility

Designed for go inspection use with micrometers, verniers, and other precision measuring devices where a 0.35 mm diameter plug gage is required per ASME B89.1 specifications.

Installation Notes

Plug gages of this class are handled and used by quality technicians and machinists in controlled inspection environments. Store the gage in its protective case when not in use to prevent surface damage or dimensional change. Never force the gage into a bore; apply only light, consistent hand pressure to avoid wear or deflection of the gage pin. Clean contact surfaces before each use to ensure accurate readings.
