Vermont Gage 112303350 Class Zz Plus Plug Gage 3.35 Mm

Product Description

The VERMONT GAGE 112303350 is a Class ZZ Plus plug gage designed for precise bore and hole inspection in quality control and metrology applications. Manufactured from tool steel, this pin-style gage has a 3.35 mm diameter and holds a tolerance of 0.00508 mm, meeting ASME B89.1 standards. The 10 microfinish surface provides a consistent, repeatable contact surface critical for accurate dimensional verification. Each unit ships with a Certificate of Accuracy traceable to NIST, making it suitable for documented inspection processes. Licensed metrologists, machinists, and quality technicians are the primary users of this instrument.

This plug gage is used in Go inspection routines to verify that a hole or bore meets minimum dimensional requirements. It is applicable across light manufacturing, precision machining shops, and calibration labs where tight tolerances must be confirmed before parts advance in production. The 112303350 is also used for setting and verifying micrometers, verniers, and other measuring devices requiring a known reference standard. The overall length of 2.0000 inches suits standard pin gage handles and setting fixtures.

Key Features

• 3.35 mm diameter with 0.00508 mm tolerance for precise Go inspection
• Tool steel construction for durability and dimensional stability
• 10 microfinish surface for consistent, accurate contact
• Meets ASME B89.1 dimensional standards
• Includes Certificate of Accuracy with NIST traceability for documented QC processes

Compatibility

Designed for use as a Go plug gage in standard pin gage handle systems. Also suitable for setting micrometers, verniers, and other measuring devices requiring a traceable reference standard at 3.35 mm diameter.

Installation Notes

Plug gages are handled and used by quality technicians and machinists familiar with dimensional metrology practices. Store in a protective case away from moisture and contaminants to maintain the 10 microfinish surface and dimensional integrity. When inserting the gage into a bore, apply light, consistent hand pressure only — never force the gage or use mechanical aids. Calibration intervals should follow the facility quality management system and applicable metrology standards.
