Vermont Gage 112303630 Class Zz Plus Plug Gage 3.63mm

Product Description

The VERMONT GAGE 112303630 is a Class ZZ Plus cylindrical plug gage manufactured from tool steel for dimensional inspection of internal bores and holes. It measures 3.63 mm in diameter with a tolerance of 0.00508 mm and a 10 microfinish surface finish. The overall length is 2.0000 inches. Designed for Go inspection applications, this gage is used to verify that a drilled, reamed, or bored hole falls within its minimum acceptable size. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting ASME B89.1 standards. Machinists, quality technicians, and metrology personnel are the primary users.

This plug gage is suited for production floor and metrology lab use in applications requiring tight tolerance verification. It is appropriate for Go inspection checks on precision-machined components and for setting or verifying micrometers, verniers, and other measuring devices. The 3.63 mm diameter makes it applicable to small-bore inspection work common in precision manufacturing, tooling, and mechanical assembly environments.

Key Features

• Class ZZ Plus tolerance grade with 0.00508 mm tolerance for precision Go inspection
• 10 microfinish surface finish reduces wear and ensures consistent gage contact
• Tool steel construction provides hardness and dimensional stability under repeated use
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 standards
• Compact 2.0000-inch overall length suits bench and handheld inspection tasks

Compatibility

Designed for Go inspection use with micrometers, verniers, and other measuring devices requiring a 3.63 mm reference standard. Suitable as an OEM-style precision gage for small-bore inspection setups in conformance with ASME B89.1.

Installation Notes

Plug gages of this type are handled and applied by quality technicians or machinists during inspection procedures. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel surface. Do not force the gage into a bore; apply only enough manual pressure to confirm fit. Store in a protective case away from temperature extremes to maintain dimensional stability.
