Vermont Gage 112311650 Class Zz Plus Plug Gage 11.65mm

Product Description

The VERMONT GAGE 112311650 is a Class ZZ Plus cylindrical plug gage with an 11.65 mm diameter, designed for go-inspection of bored, reamed, and drilled holes in precision manufacturing environments. Built from tool steel and finished to a 10 microfinish surface, it delivers consistent, reliable dimensional verification. The gage holds a tolerance of 0.00508 mm, making it suitable for applications where tight dimensional control is required. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting ASME B89.1 standards. Machinists, quality technicians, and metrology professionals use this gage as part of incoming inspection, in-process checks, and final acceptance routines.

This plug gage is used in machine shops, manufacturing cells, and quality labs where hole diameter verification is part of standard process control. It is suited for go inspection of workpieces where the nominal hole diameter is 11.65 mm. It also serves as a reference standard for setting micrometers, verniers, and other measuring devices to a known dimension. The compact overall length of 2.0000 inches makes it easy to handle and store in a standard gage block set or inspection kit.

Key Features

• Class ZZ Plus tolerance class for go-inspection duty
• 11.65 mm nominal diameter with 0.00508 mm tolerance
• 10 microfinish surface for accurate contact and reduced wear
• Tool steel construction for hardness and dimensional stability
• Includes Certificate of Accuracy with NIST traceability
• Meets ASME B89.1 standards for plain limit gages

Compatibility

Designed for go inspection of holes with a nominal diameter of 11.65 mm. Also suitable for use as a setting standard with micrometers, verniers, and other measuring devices requiring a known reference dimension.

Installation Notes

Plug gages are handled and used by quality technicians and machinists in inspection settings, not installed in a mechanical system. Keep the gage clean and lightly oiled when not in use to prevent corrosion. Never force a go gage through a hole; if resistance is felt, the hole is undersize and should be re-evaluated. Store the gage in its case away from heat sources and abrasive materials to maintain calibration integrity.
