Vermont Gage 112111720 Class Zz Plus Plug Gage 11.72mm

Product Description

The VERMONT GAGE 112111720 is a Class ZZ Plus cylindrical plug gage designed for precise go inspection of bored, reamed, and drilled holes. It features an 11.72 mm diameter with a tolerance of 0.00508 mm, making it suitable for high-accuracy dimensional verification. The 10 microfinish surface provides consistent, repeatable gauge contact. Machined from tool steel for durability and dimensional stability, this plug gage includes a Certificate of Accuracy with NIST traceability, meeting ASME B89.1 standards. Metrology technicians, machinists, and quality control inspectors use this gage for go-type attribute inspection in production and inspection environments.

The 112111720 plug gage is used in go inspection applications to verify that a hole or bore meets minimum diameter specifications. It is appropriate for use alongside set micrometers, verniers, and other precision measuring devices during incoming inspection, in-process quality checks, or final part verification. With an overall length of 2.0 inches and a compact form factor, it suits benchtop inspection stations and floor-level use. The included NIST-traceable Certificate of Accuracy supports quality system documentation requirements such as ISO 9001 or AS9100 programs.

Compatibility

Designed as an OEM-style go plug gage compatible for use with set micrometers, verniers, and other precision measuring devices requiring an 11.72 mm diameter reference standard.

Installation Notes

Plug gages are handled and used by metrology technicians and quality inspectors. Store the gage in its protective case when not in use to prevent surface damage and contamination. Clean the gage and the workpiece hole before gauging to prevent debris from affecting readings or causing premature wear. Never force the plug gage into a hole, as this can damage the gage surface and invalidate measurement accuracy.
