Vermont Gage 112400390 Class Zz Minus Plug Pin Gage 0.39 Mm

Product Description

The VERMONT GAGE 112400390 is a Class ZZ Minus plug pin gage used to verify that a hole or bore does not exceed its maximum allowable size. Built from steel with a 10 microfinish surface coating, this gage measures a nominal diameter of 0.39 mm with a tolerance of 0.00508 mm. It has an overall length of 2 inches. The part ships with a Certificate of Accuracy that carries NIST traceability, confirming the measurement standard behind each unit. Machinists, quality control technicians, and tool-and-die professionals use this type of gage on the shop floor for NoGo inspection work where tight dimensional control is required.

This plug pin gage is sized for NoGo inspection applications and is also suitable for setting and verifying micrometers, verniers, and other precision measuring devices. The 0.39 mm diameter makes it appropriate for small-bore and precision-hole inspection tasks common in manufacturing, machining, and metrology environments. Its compact size and included NIST-traceable accuracy certificate make it ready for use in quality programs that require documented traceability to a national measurement standard.

Key Features

• Class ZZ Minus tolerance class: 0.00508 mm tolerance for reliable NoGo inspection
• 10 microfinish surface coating for consistent contact and reduced wear on gauged surfaces
• Steel construction for durability in shop-floor conditions
• 2-inch overall length for easy handling during inspection
• Includes Certificate of Accuracy with NIST traceability for documented quality programs
• Compatible with micrometers, verniers, and other precision measuring devices as a setting reference

Compatibility

Designed for NoGo plug gage inspection applications and for setting micrometers, verniers, and other precision measuring devices requiring a 0.39 mm reference diameter.

Installation Notes

Plug pin gages are handled and used by metrology technicians and quality control personnel, not installed in a mechanical system. Store the gage in its case or protective sleeve when not in use to prevent surface damage. Clean contact surfaces before use and avoid dropping or striking the gage, as impact can affect calibration. Follow your facility's gage control program for calibration intervals and handling procedures.
