Vermont Gage 111311050 Class Zz Plus Plug Gage 0.1105 in

Product Description

The VERMONT GAGE 111311050 is a Class ZZ Plus plug gage manufactured from tool steel for dimensional go inspection work. It measures a nominal diameter of 0.1105 inches with a tolerance of 0.0002 inches, making it suitable for precision quality control on the shop floor or in the inspection lab. The 111311050 carries a 10 microfinish surface on the gage member, which reduces wear on both the gage and the workpiece bore during repeated use. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming conformance to ASME B89.1 standards. Licensed metrology technicians, machinists, and quality inspectors are the primary users of this tool.

This plug gage is used in go inspection applications where a technician needs to verify that a drilled, reamed, or bored hole meets the minimum acceptable size before a part advances in the production process. It is also a calibration reference for setting micrometers, verniers, and other measuring devices to a known diameter. Typical installation environments include machine shops, manufacturing inspection stations, and metrology labs handling small-diameter precision parts. The 2.0-inch overall length provides adequate handling clearance for most standard workholding setups.

Key Features

• Nominal measurement diameter of 0.1105 inches for small-bore go inspection
• Tolerance of 0.0002 inches per Class ZZ Plus specification
• 10 microfinish surface reduces gage and bore wear during repeated checks
• Tool steel construction for hardness and dimensional stability
• Overall length of 2.0 inches for practical bench and in-fixture handling
• Includes Certificate of Accuracy with NIST traceability, conforming to ASME B89.1

Compatibility

Designed as an OEM-style go plug gage for use with standard gage handle systems and as a setting reference for micrometers, verniers, and comparable precision measuring devices requiring a 0.1105-inch diameter reference standard.

Installation Notes

Plug gages should be handled by metrology or quality inspection personnel following shop calibration procedures. Store the gage in its protective case when not in use to prevent corrosion and surface damage to the gage member. Never force the gage through a bore; go gages should pass through the workpiece hole under the weight of the gage alone or with light hand pressure. Recalibrate or remove from service if the gage member shows visible wear, scoring, or fails a master-ring verification check.
