Vermont Gage 111169300 Class Zz Plus Plug Gage 0.693 in

Product Description

The VERMONT GAGE 111169300 is a Class ZZ Plus plug gage used to verify bore and hole dimensions in precision machining and quality-control applications. It measures a nominal diameter of 0.693 inches with a tolerance of 0.0002 inches, providing the accuracy required for go inspection work. The gage is manufactured from tool steel and carries a 10 microinch surface finish. Overall length is 2.0 inches. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting the documentation requirements of most quality management systems. Machinists, tool-room technicians, and QC inspectors are the primary users of this type of gage.

This plug gage is suited for go inspection tasks in production and tool-room environments. It is used to verify that bored, drilled, or reamed holes fall within acceptable dimensional limits before assembly or further machining. It is also appropriate for setting and checking micrometers, vernier calipers, and other comparative measuring devices. Typical installation environments include job shops, production floors, and inspection labs handling tight-tolerance metal or plastic components. The gage complies with ASME B89.1 standards, making it suitable for regulated manufacturing contexts.

Compatibility

Designed as an OEM-style go inspection plug gage suitable for use with standard gage handles accepting 0.693 inch diameter gage members, and compatible with micrometers, verniers, and other comparative measuring devices as stated in the product application data.

Installation Notes

Plug gages of this type are handled and used by machinists and quality-control technicians. Ensure the workpiece and gage are at or near the same ambient temperature before measurement to avoid thermal expansion errors. Clean both the gage and the bore with a lint-free cloth before use. Do not force the gage member into a hole; go members should pass under their own weight or with minimal hand pressure when the bore is within tolerance.
