Vermont Gage 111335750 Class Zz Plus Plug Gage 0.3575 in

Product Description

The VERMONT GAGE 111335750 is a Class ZZ Plus plug gage used to verify bore and hole dimensions to close tolerances in production and inspection environments. Machined from tool steel and finished to a 10 microfinish surface, this gage holds a dimensional tolerance of 0.0002 inches on a 0.3575-inch diameter. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting quality-system documentation requirements. It is the standard choice for machinists, quality technicians, and metrology personnel who need a reliable go-inspection reference on the shop floor or in a gage room.

This plug gage is suited for go inspection of holes, bores, and openings measuring 0.3575 inches in diameter. It is also used to set and verify micrometers, verniers, and other measuring devices where a certified reference standard is required. Overall length is 2.0 inches, making it easy to handle for both bench inspection and in-process checks on machined components in light manufacturing and precision machining operations. Typical users include quality control technicians, tool-and-die makers, and CNC machinists.

Key Features

• 0.3575-inch measurement diameter with a tight 0.0002-inch tolerance for precise go inspection
• 10 microfinish surface finish reduces wear on mating bores and ensures repeatable contact
• Tool steel construction provides hardness and dimensional stability under regular use
• Complies with ASME B89.1 standards for plain plug gages
• Includes Certificate of Accuracy with NIST traceability for quality-system and audit requirements
• Overall length of 2.0 inches suits both benchtop and in-process inspection tasks

Compatibility

Designed for go inspection of 0.3575-inch diameter features and for use as a setting reference with micrometers, verniers, and other measuring devices as stated by the manufacturer.

Installation Notes

Plug gages are handled and stored by metrology or quality personnel, not installed in a system. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel body. Never force the gage into a bore; apply only light hand pressure to avoid damaging the gage or the workpiece. Store in a protective case away from temperature extremes to maintain dimensional stability.
