Vermont Gage 112408970 Class Zz Minus Plug Pin Gage 8.97 Mm

Product Description

The VERMONT GAGE 112408970 is a Class ZZ Minus plug pin gage designed for NoGo inspection applications in precision measurement work. Machined from steel and finished to a 10 microfinish surface, this pin gage measures a nominal diameter of 8.97 mm with a tolerance of 0.00508 mm. The overall length is 2 inches. Each unit ships with a Certificate of Accuracy with NIST Traceability, making it suitable for calibration-controlled environments. Quality control technicians, machinists, and metrology professionals use this gage to verify that a hole or bore does not exceed its maximum allowable size.

Class ZZ Minus pin gages are used in go/nogo inspection routines on production floors, in quality labs, and in tool rooms. The minus designation means the gage is ground to the low side of the nominal diameter, which is standard practice for NoGo members. This gage is appropriate for inspecting bored, drilled, or reamed holes in metal or plastic workpieces where tight dimensional control is required. It is also used to set and verify micrometers, verniers, and other measuring devices that require a traceable reference standard.

Installation Notes

Pin gages are handled and stored by metrology or quality control personnel, not installed in the field. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the steel surface. Never force a pin gage into a hole; if resistance is felt, the bore may be undersize or contain debris. Store in the original protective case and re-certify on a schedule consistent with your facility quality management system.
