Vermont Gage 112317910 Class Zz Plus Plug Gage 17.91mm

Product Description

The VERMONT GAGE 112317910 is a Class ZZ Plus plug gage used to verify bore and hole dimensions in precision inspection environments. The gage measures 17.91 mm in diameter and is manufactured from tool steel with a 10 micro finish coating. It carries a tolerance of 0.005 mm, making it suitable for go inspection tasks where accurate dimensional verification is required. A Certificate of Accuracy with NIST traceability is included with each unit. Machinists, quality technicians, and metrology lab personnel use this gage to confirm that drilled, reamed, or bored features fall within specified limits before parts advance through the production process.

This plug gage is intended for use in go inspection applications on the shop floor or in the metrology lab. Compatible measuring contexts include use alongside set micrometers, verniers, and other precision measuring devices. The gage suits both incoming inspection and in-process quality checks in manufacturing environments where tight dimensional tolerances must be held. It is appropriate for use in general metalworking, tooling, and precision machining operations. With an overall length of 2.0000 inches, it handles standard bore depths in typical workpiece configurations without requiring an extension handle in most cases.

Key Features

• 17.91 mm nominal diameter for precise go inspection of bored and reamed features
• Class ZZ Plus tolerance of 0.005 mm for accurate dimensional verification
• Tool steel construction with 10 micro finish coating for durability and surface consistency
• Conforms to ASME B89.1 standards for plain limit gages
• Includes Certificate of Accuracy with NIST traceability for documentation and calibration records
• Overall length of 2.0000 inches suits standard workpiece configurations

Compatibility

Designed for use in go inspection of bored, drilled, and reamed holes nominally sized at 17.91 mm. Also compatible with set micrometers, verniers, and other precision measuring devices as a reference standard.

Installation Notes

Plug gages are handled and used by quality technicians and machinists trained in precision measurement practices. Keep the gage clean and lightly oiled when not in use to prevent corrosion of the tool steel surface. Do not force the gage into a bore; apply only light, steady hand pressure to avoid damage to the gage or the workpiece. Store in a protective case away from heat sources to maintain dimensional stability and preserve NIST-traceable calibration status.
