Vermont Gage 111305850 Class Zz Plus Plug Gage 0.0585 in

Product Description

The VERMONT GAGE 111305850 is a Class ZZ Plus plug gage designed for precise go-inspection of bored holes, machined openings, and similar features requiring tight dimensional verification. Manufactured from tool steel with a 10 microfinish surface, this gage measures a nominal diameter of 0.0585 inches with a tolerance of 0.0002 inches. It is 2.0 inches in overall length, making it suitable for bench-top inspection work in machine shops, toolrooms, and quality-control environments. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming conformance to ASME B89.1 standards.

This plug gage is used for go inspection of precision bored or drilled holes at the 0.0585-inch diameter class. Typical applications include verifying hole size on machined components before assembly, calibrating or checking set micrometers, verniers, and other measuring devices. It is appropriate for both production floor inspection and toolroom metrology in industrial and manufacturing settings. The small diameter makes it especially relevant for precision work in watchmaking, medical device manufacturing, aerospace component inspection, and similar fine-tolerance industries.

Key Features

• Class ZZ Plus tolerance rating for go-inspection accuracy in precision measurement applications
• 0.0585-inch nominal measurement diameter with 0.0002-inch tolerance
• 10 microfinish surface coating for consistent, low-wear contact during repeated use
• Tool steel construction provides hardness and dimensional stability over time
• Includes Certificate of Accuracy with NIST traceability, conforming to ASME B89.1
• Compact 2.0-inch overall length suitable for bench inspection and measuring-device calibration

Compatibility

Designed for go inspection of holes and bores at 0.0585-inch diameter. Also suitable for setting and checking micrometers, verniers, and other precision measuring devices requiring a certified reference standard at this diameter.

Installation Notes

Plug gages are handled and used by quality technicians, machinists, and toolroom personnel. Store the gage in its protective case when not in use and keep it free of contaminants, oils, and debris that can affect measurement accuracy. Do not force the gage into a hole; apply only light, consistent hand pressure to avoid wear or damage to the gage or workpiece. Periodic recertification is recommended per facility quality-management procedures and applicable metrology standards.
