Vermont Gage 112402810 Class Zz Minus Plug Pin Gage 2.81mm

Product Description

The VERMONT GAGE 112402810 is a Class ZZ Minus plug pin gage machined from steel and used to verify that a bored or drilled hole does not exceed its maximum allowable size. With a measurement diameter of 2.81 mm and a tolerance of 0.00508 mm, this gage delivers the precision required for NoGo inspection work. The 10 Microfinish surface coating reduces wear and maintains dimensional integrity over repeated use. Each unit ships with a Certificate of Accuracy traceable to NIST standards, making it suitable for documented quality-control processes. Licensed metrologists, machinists, and quality technicians are the primary users of this tool.

This pin gage is designed for NoGo inspection applications where a hole or bore must be verified as within its maximum material condition limit. It is also appropriate for setting and checking micrometers, verniers, and other precision measuring devices that require a certified reference standard. At 2 inches overall length, it fits comfortably in a hand or pin gage handle for bench and floor inspection use in machine shops, manufacturing cells, and quality labs.

Key Features

• Includes Certificate of Accuracy with NIST traceability for documented QC processes
• Steel construction for durability in production and inspection environments
• 2-inch overall length compatible with standard pin gage handles and fixtures

Compatibility

Designed for use in NoGo hole inspection applications and as a reference standard for setting micrometers, verniers, and other precision measuring devices requiring a certified pin reference.

Installation Notes

Pin gages are handled and stored by metrology and quality technicians following standard gage-handling procedures. Keep the gage clean and lightly oiled when stored to prevent corrosion on the steel surface. Never force the gage into a hole or bore; the part being inspected should accept or reject the pin with light, controlled hand pressure only. Store in the supplied case or a dedicated gage block tray away from impact hazards to preserve the certified tolerance.
