Vermont Gage 112402750 Class Zz Minus Plug Pin Gage 2.75mm

Product Description

The VERMONT GAGE 112402750 is a Class ZZ Minus plug pin gage machined from steel for NoGo inspection work. It measures 2.75 mm in diameter with a tolerance of 0.00508 mm, making it suitable for precise go/no-go inspection of bored holes, drilled passages, and machined features. The overall length is 2 inches. A 10 microfinish surface coating provides consistent contact with the gage surface. Each unit ships with a Certificate of Accuracy traceable to NIST, satisfying documentation requirements for calibrated tooling in quality-controlled environments. Machinists, quality technicians, and tool-and-die professionals use this type of gage as part of dimensional inspection routines on the shop floor or in the metrology lab.

This pin gage is used in NoGo inspection applications where a hole or bore must not accept a gage of the specified diameter. It is also compatible with setting and verifying micrometers, verniers, and other measuring devices that require a known reference. Typical deployment is in machine shops, manufacturing facilities, and metrology labs performing dimensional quality control on precision-machined components. The 2.75 mm diameter targets metric-dimensioned work.

Installation Notes

Pin gages require no installation in the traditional sense but should be handled with clean, dry hands or cotton gloves to prevent corrosion from skin oils. Store in the supplied case or a designated gage block tray when not in use. Clean contact surfaces with a lint-free cloth and appropriate instrument cleaner before and after each use. Periodic recalibration against a traceable standard is recommended to maintain measurement integrity.
