Vermont Gage 111445750 Class Zz Minus Plug Pin Gage 0.4575 in

Product Description

The VERMONT GAGE 111445750 is a Class ZZ Minus plug pin gage with a 0.4575-inch diameter, designed for NoGo inspection applications in precision measurement work. Machined from steel with a 10 microfinish surface coating, this pin gage delivers consistent dimensional verification for quality control processes. Each unit includes a Certificate of Accuracy with NIST traceability, confirming it meets Class ZZ minus tolerance standards of 0.0002 inches. Machinists, quality technicians, and toolroom professionals use this gage to verify that bores, holes, and features do not exceed the maximum allowable size limit.

This plug pin gage is suited for use in production inspection environments, toolrooms, and quality labs where accurate NoGo gauging is required. At 2 inches in overall length, it is sized for convenient single-hand use. Compatible applications include setting micrometers, vernier calipers, and other measuring devices requiring a traceable reference standard. It is appropriate for both shop-floor dimensional checks and bench-level metrology tasks in aerospace, manufacturing, and general machining operations.

Installation Notes

Pin gages are handled and stored by quality technicians and toolroom personnel — no power shutoff is required. Keep the gage clean and lightly oiled when not in use to prevent corrosion and protect the precision-ground surface. Avoid dropping or striking the gage, as any impact can alter dimensional accuracy. Store in the provided case or a protected location away from abrasive materials.
