Vermont Gage 111136200 Class Zz Plus Plug Gage 0.362 in

Product Description

The VERMONT GAGE 111136200 is a Class ZZ Plus plug gage used to verify bore and hole diameters to a high degree of dimensional accuracy. Manufactured from tool steel, this go-inspection gage measures a nominal diameter of 0.362 inches with a tolerance of 0.0002 inches. The 10 microfinish surface provides consistent, repeatable contact across inspection cycles. At 2.0 inches in overall length, it is sized for bench-top use in quality control and metrology environments. Each unit ships with a Certificate of Accuracy backed by NIST traceability, making it suitable for calibrated inspection records and audit documentation. Licensed metrologists, machinists, and quality technicians are the primary users of this instrument.

This plug gage is used in go inspection applications to confirm that machined holes and bores fall within specified dimensional tolerances. It is also used to set micrometers, verniers, and other comparative measuring devices to a known reference diameter. Typical environments include machine shops, manufacturing quality lines, and calibration labs working to ASME B89.1 standards. The 0.362-inch diameter range addresses common small-bore inspection tasks in both production and incoming-goods inspection workflows.

Key Features

• Class ZZ Plus tolerance grade at 0.0002 inches for precise go-inspection use
• 10 microfinish surface for consistent gage-to-workpiece contact
• Tool steel construction for durability and dimensional stability over repeated use
• NIST-traceable Certificate of Accuracy included for calibration recordkeeping
• Conforms to ASME B89.1 dimensional gage standards
• 2.0 inches overall length suitable for standard bench and hand-held inspection use

Compatibility

Designed as an OEM-style go plug gage for inspecting bores and holes at 0.362 inches nominal diameter and for setting micrometers, verniers, and other comparative measuring instruments.

Installation Notes

Plug gages should be handled with clean, dry hands or lint-free gloves to prevent corrosion from skin oils. Store the gage in its case or on a padded surface away from other metal tools to avoid contact damage to the lapped surface. Before use, verify the gage and workpiece are at ambient temperature, typically 68 degrees F per ASME B89.1 reference conditions, to minimize thermal expansion error. Periodic recalibration intervals should follow your facility quality management plan.
