Vermont Gage 112316570 Class Zz Plus Plug Gage 16.57mm

Product Description

The VERMONT GAGE 112316570 is a Class ZZ Plus plug gage designed for precision dimensional inspection of bored holes and machined features. Built from tool steel with a 10 micro-inch finish coating, it holds a tolerance of 0.00508 mm, making it suitable for Go inspection applications where accurate pass/fail verification is required. The gage ships with a Certificate of Accuracy that carries NIST traceability, supporting quality documentation requirements in machine shops, toolrooms, and production inspection environments. It measures 16.57 mm in diameter with an overall length of 2.0000 inches.

This plug gage is intended for use in Go inspection workflows alongside micrometers, verniers, and other precision measuring devices. It is a standard choice for machinists, quality technicians, and tool room professionals verifying hole diameters to ASME B89.1 tolerances in both job-shop and production settings. The compact size and single-piece format make it easy to integrate into an existing gage set or use as a standalone reference standard.

Key Features

• Class ZZ Plus tolerance rating with 0.00508 mm (0.005 mm) tolerance for precise Go inspection
• Tool steel construction with 10 micro-inch finish coating for durability and measurement consistency
• NIST-traceable Certificate of Accuracy included for quality and audit compliance
• Conforms to ASME B89.1 dimensional standards
• Overall length of 2.0000 inches for easy handling in typical bore-checking applications

Compatibility

Designed as an OEM-style precision reference tool for use with Go inspection setups, set micrometers, verniers, and other calibrated measuring devices requiring a 16.57 mm diameter plug reference.

Installation Notes

Plug gages are installed and used by quality technicians and machinists; no power shutoff is required, but the work area and measured feature should be clean and free of chips or coolant before use. Handle the gage with care to avoid surface contact that could alter the finish or introduce dimensional error. Store in the provided case or a clean, dry environment to preserve the tool steel surface and calibration integrity. Reference ASME B89.1 for inspection procedure and environmental temperature requirements.
