Vermont Gage 112311270 Class Zz Plus Plug Gage 11.27mm

Product Description

The VERMONT GAGE 112311270 is a Class ZZ Plus cylindrical plug gage designed to verify bore diameters with precision in production and inspection environments. It has a nominal diameter of 11.27 mm and holds a tolerance of 0.00508 mm, making it appropriate for Go inspection tasks where confirming that a hole falls within the acceptable lower limit is required. The gage body is machined from tool steel and features a 10 microfinish surface coating on the gaging member. Each unit ships with a Certificate of Accuracy traceable to NIST standards. Dimensional inspection technicians and quality control professionals are the primary users.

This plug gage is suited for use in machine shops, tool rooms, and quality assurance labs handling precision bore inspection. Typical applications include verifying drilled, reamed, or bored holes as part of a Go/No-Go inspection process. It is also compatible with use alongside set micrometers, verniers, and other calibrated measuring devices as a reference standard. The 2.0000-inch overall length provides adequate handling clearance in most workholding setups. Conformance is stated to ASME B89.1.

Compatibility

Designed for Go inspection of 11.27 mm diameter bores and for use as a reference standard with set micrometers, verniers, and other precision measuring devices in compliance with ASME B89.1.

Installation Notes

Plug gages are handled by metrology technicians and quality inspection personnel, not requiring installation in the traditional sense. Store the gage in its protective case when not in use to prevent surface damage or corrosion on the tool steel gaging member. Clean contact surfaces with a lint-free cloth and apply a light coat of instrument oil during storage. Never force the gage into a bore; if resistance is encountered, the hole is undersized and should be re-evaluated.
