Vermont Gage 111237400 Class Zz Minus Plug Pin Gage 0.374 in

Product Description

The VERMONT GAGE 111237400 is a Class ZZ Minus plug pin gage machined from steel and used to verify that a hole or bore does not exceed its maximum allowable size during NoGo inspection. The gage measures 0.3740 inches in diameter and holds a tolerance of 0.0002 inches, making it suitable for precision dimensional inspection in manufacturing and machining environments. A Certificate of Accuracy with NIST Traceability is included, supporting quality documentation requirements in regulated production settings. Machinists, quality technicians, and metrology professionals install and use this gage as part of go/nogo inspection routines.

This plug pin gage is used in applications requiring NoGo hole inspection, as well as for setting and verifying micrometers, verniers, and other measuring devices. Its 0.3740 inch diameter makes it appropriate for inspecting bored, drilled, or reamed holes in steel, aluminum, and similar workpiece materials. At 2 inches in overall length, it fits comfortably in a standard pin gage handle. It is suited for both production floor inspection and toolroom metrology work.

Installation Notes

Pin gages are installed and used by machinists and quality technicians following standard metrology practices. Handle the gage with clean, dry hands or inspection gloves to prevent corrosion from skin oils. Store the gage in its protective case when not in use to maintain surface finish and dimensional integrity. Periodic recalibration against traceable standards is recommended to confirm ongoing accuracy.
