Vermont Gage 111347450 Class Zz Plus Plug Gage 0.4745 in

Product Description

The VERMONT GAGE 111347450 is a Class ZZ Plus plug gage machined from tool steel for dimensional inspection of hole diameters. Designed to verify whether a bored or drilled feature falls within acceptable tolerance, this gage is built to ASME B89.1 standards with a 0.0002 inch tolerance and a 10 microfinish surface finish. The nominal measurement diameter is 0.4745 inches, and the overall length is 2.0 inches. Each unit ships with a Certificate of Accuracy backed by NIST traceability, making it suitable for documented inspection programs in production and quality-control environments. Machinists, quality technicians, and metrology professionals are the primary end users.

This plug gage is used for Go inspection applications in manufacturing and machining shops. It is also used to calibrate and verify the accuracy of set micrometers, verniers, and other handheld measuring devices. Typical installation scenarios include incoming inspection of machined components, in-process quality checks on CNC-machined bores, and periodic instrument verification on the shop floor. The compact 2.0-inch overall length makes it easy to handle in both bench and floor inspection environments.

Key Features

• ASME B89.1 standard compliance for dimensional plug gage accuracy
• 0.0002 inch tolerance for precise Go inspection of 0.4745 inch diameter features
• 10 microfinish surface finish for consistent, repeatable contact
• Tool steel construction for durability and wear resistance
• Includes Certificate of Accuracy with NIST traceability for documented QC programs
• 2.0 inch overall length for convenient bench and floor use

Compatibility

Designed for Go inspection of 0.4745 inch diameter bores and for use as a reference standard when setting micrometers, verniers, and other dimensional measuring devices.

Installation Notes

Plug gages should be handled by quality technicians or metrology personnel familiar with ASME B89.1 inspection practices. Keep the gage clean and lightly oiled when not in use to prevent corrosion of the tool steel surface. Never force the gage into a bore; excessive force can damage both the gage and the workpiece. Store in its case or protective sleeve when not in active use to preserve the microfinish surface.
