Vermont Gage 911104100 Class Zz Plus Plug Gage 0.041 in

Product Description

The VERMONT GAGE 911104100 is a Class ZZ Plus plug gage designed for precision dimensional inspection of small bored holes and machined openings. Built from tool steel with a black oxide finish, this gage measures a nominal diameter of 0.041 inches with a tolerance of 0.0002 inches, making it suitable for go inspection workflows where repeatable, traceable measurement is required. It ships with a Certificate of Accuracy with NIST Traceability, confirming conformance to ASME B89.1 standards. Metrology technicians, toolroom machinists, and quality control inspectors rely on this type of instrument for tight-tolerance verification tasks.

This plug gage is used in shop-floor and laboratory environments for go inspection of precision holes. It is also used to calibrate and verify the accuracy of micrometers, vernier calipers, and other measuring devices. With an overall length of 2 inches and a 0.041-inch measurement diameter, it fits into small-bore inspection tasks common in precision machining, tooling manufacture, and quality assurance operations. Single-piece packaging makes it straightforward to order and deploy as a replacement or addition to an existing gage set.

Key Features

• Class ZZ Plus tolerance rating at 0.0002 inches for tight-tolerance go inspection
• Tool steel construction for hardness and wear resistance in repeated-use environments
• Black oxide finish provides corrosion resistance and reduces surface glare during inspection
• Includes Certificate of Accuracy with NIST Traceability per ASME B89.1
• 0.041-inch measurement diameter with a 2-inch overall length for small-bore applications
• Suitable for verifying micrometers, verniers, and other precision measuring devices

Compatibility

Designed for go inspection of precision bored holes at 0.041 inches nominal diameter and for use in setting and verifying micrometers, vernier calipers, and comparable measuring instruments requiring a certified reference standard.

Installation Notes

Plug gages are handled and used by metrology technicians and toolroom personnel following standard inspection procedures. Keep the gage clean and lightly oiled when not in use to prevent corrosion. Do not force the gage into an undersized bore, as this will damage both the gage and the workpiece. Store in a protective case away from abrasive materials and temperature extremes to maintain calibration integrity.
