Vermont Gage 111408750 Class Zz Minus Plug Pin Gage 0.0875 in

Product Description

The VERMONT GAGE 111408750 is a Class ZZ Minus plug pin gage designed for NoGo inspection applications in precision measurement work. Machined from steel with a 10 microfinish surface coating, this pin gage measures a nominal diameter of 0.0875 inches with a tolerance of 0.0002 inches, making it suitable for verifying that a bored hole or feature does not exceed the maximum allowable size. Each unit ships with a Certificate of Accuracy traceable to NIST standards, confirming dimensional conformance at the point of manufacture. Overall length is 2 inches. Machinists, quality control technicians, and tool room personnel are the primary users of this type of gage.

This pin gage is used in machine shops, manufacturing facilities, and inspection departments where tight hole tolerances must be verified. It is appropriate for use alongside micrometers, verniers, and other precision measuring devices. The NoGo classification means this gage is applied to confirm rejection of out-of-tolerance features — if the pin enters the hole, the hole is oversized. It is suited for both production-floor spot checks and formal inspection routines on small-diameter bored features.

Key Features

• Class ZZ Minus tolerance classification for NoGo inspection use
• 0.0875 inch nominal measurement diameter with 0.0002 inch tolerance
• Steel construction with 10 microfinish surface coating for accurate contact
• 2 inch overall length for controlled handling during inspection
• Includes Certificate of Accuracy with NIST traceability
• Compatible with micrometers, verniers, and standard measuring setups

Compatibility

Designed for use in NoGo inspection routines and as a companion gage with micrometers, verniers, and other precision measuring devices requiring a 0.0875 inch diameter Class ZZ Minus pin reference.

Installation Notes

Pin gages of this type are handled by qualified inspection or tool room personnel and require no installation in the traditional sense. Clean the gage and the feature being inspected before use to prevent debris from affecting readings. Store the pin gage in a protective case away from moisture and other tools to preserve the machined surface finish and dimensional integrity. Do not force the pin into a feature — proper NoGo technique relies on light, controlled insertion pressure only.
