Vermont Gage 112403610 Class Zz Minus Plug Pin Gage 3.61mm

Product Description

The VERMONT GAGE 112403610 is a Class ZZ minus plug pin gage used for NoGo inspection of precision bored holes and machined features. It measures 3.61 mm in diameter with a tolerance of 0.00508 mm, making it suitable for high-accuracy dimensional verification in production and quality control environments. The gage is machined from steel and finished to a 10 microfinish surface for consistent contact and reliable readings. At 2 inches in overall length, it fits standard pin gage handles and holders. Each unit ships with a Certificate of Accuracy with NIST Traceability, confirming that the gage meets documented metrology standards required in many shop and inspection environments.

This plug pin gage is designed for use in dimensional inspection applications where NoGo verification is required. It is compatible with set micrometers, verniers, and other calibrated measuring devices used during incoming inspection, in-process checks, or final quality audits. Machinists, quality control technicians, and metrology professionals in manufacturing, aerospace, automotive, and general precision machining environments rely on Class ZZ pin gages for fast, repeatable go or nogo checks on drilled, reamed, or bored features at the 3.61 mm nominal size.

• Steel construction with 10 microfinish surface for consistent contact
• 2 inch overall length fits standard pin gage handles and holders
• Includes Certificate of Accuracy with NIST Traceability
• Compatible with set micrometers, verniers, and other precision measuring devices

Compatibility

Designed for use with standard pin gage handles and holders, and compatible with set micrometers, verniers, and other precision measuring devices used in dimensional inspection of 3.61 mm nominal bore features.

Installation Notes

Pin gages are handled and used by quality control technicians and machinists in inspection environments. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the steel surface. Do not force the gage into a feature; apply only light hand pressure to avoid damage to the gage or the workpiece. Store in the original case or a protective sleeve to preserve the precision ground finish and NIST-traceable calibration status.
