Vermont Gage 911318750 Class Zz Plus Plug Gage 0.1875 in

Product Description

The VERMONT GAGE 911318750 is a Class ZZ Plus plug gage designed for precise go inspection of bored holes, machined openings, and similar features requiring tight dimensional control. Measuring a nominal diameter of 0.1875 inches with a tolerance of 0.0002 inches, this gage delivers the accuracy required for verifying work against close-tolerance specifications. Manufactured from tool steel with a black oxide finish for corrosion resistance and durability, the 911318750 has an overall length of 2 inches. A Certificate of Accuracy with NIST traceability is included, confirming that the gage meets ASME B89.1 standards. Machinists, quality control technicians, and tool room personnel use this type of gage in production and inspection environments.

This plug gage is suited for go inspection applications in machine shops, tool rooms, and manufacturing quality control stations. It is compatible with use alongside micrometers, verniers, and other precision measuring devices as a reference standard. The 0.1875 inch diameter makes it appropriate for checking drilled, reamed, or bored holes at that nominal size. Both production floor inspection and receiving inspection workflows are common applications. The compact 2 inch overall length allows use in benchtop comparator setups and hand-held inspection routines.

Key Features

• Class ZZ Plus tolerance of 0.0002 inches for high-accuracy go inspection
• Tool steel construction provides wear resistance and dimensional stability
• Black oxide finish resists corrosion during shop-floor handling
• Includes Certificate of Accuracy with NIST traceability
• Meets ASME B89.1 dimensional gage standards
• Overall length of 2 inches suits standard handle and bench setups

Compatibility

Designed for go inspection use with micrometers, verniers, and other precision measuring devices per ASME B89.1. Suitable as an OEM-style replacement or supplemental plug gage in any tool room or inspection station requiring a 0.1875 inch nominal diameter Class ZZ Plus gage.

Installation Notes

Plug gages are handled and used by quality technicians and machinists; no power source or lockout procedure is required. Keep the gage clean and lightly oiled when not in use to prevent surface corrosion on the tool steel. Do not force the gage into an undersized feature, as this will damage the gage and invalidate its calibration. Periodic recalibration against a NIST-traceable standard is recommended to maintain measurement integrity.
