Vermont Gage 112109860 Class Zz Plus Plug Gage 9.86 Mm

Product Description

The VERMONT GAGE 112109860 is a Class ZZ Plus plug gage designed for precise bore and hole inspection in machine shops, quality labs, and manufacturing environments. It measures 9.86 mm in diameter with a tolerance of 0.00508 mm, making it suitable for Go inspection applications where tight dimensional verification is required. Constructed from tool steel with a 10 microfinish surface coating, this gage delivers consistent, repeatable results. Overall length is 2.0000 inches. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting documented quality control workflows. Licensed metrologists, machinists, and quality technicians are the primary users of this tool.

This plug gage is used in applications requiring Go inspection of bored holes, machined features, and precisely toleranced openings. It is also appropriate for setting micrometers, verniers, and other measuring devices to a known reference diameter. Typical install scenarios include incoming inspection stations, in-process quality checks on CNC-machined parts, and calibration bench setups. The 9.86 mm diameter covers a common metric bore size found in precision mechanical assemblies. Its compact form and standard plug gage handle design make it easy to integrate into existing gage sets and inspection routines.

Key Features

• Class ZZ Plus tolerance rating: 0.00508 mm for high-precision Go inspection
• Tool steel construction for hardness and wear resistance in repeated use
• 10 microfinish surface coating for smooth, consistent gage contact
• Overall length of 2.0000 inches in a standard plug gage form factor
• Includes Certificate of Accuracy with NIST traceability for documented QC compliance
• Meets ASME B89.1 standard for dimensional gaging

Compatibility

Designed for use as a Go inspection plug gage in standard metric bore inspection applications and as a reference standard for setting micrometers, verniers, and comparable measuring devices.

Installation Notes

Plug gages are handled and applied by machinists, metrologists, and quality control technicians. No power tools or fasteners are required. Store the gage in its protective case when not in use to prevent surface damage or contamination that could affect measurement accuracy. Clean the gage and the bore being inspected before use, and apply light gage oil when appropriate to protect the tool steel surface and reduce wear. Follow ASME B89.1 guidelines for proper gage handling, storage, and calibration intervals.
