Vermont Gage 111401550 Class Zz Minus Plug Pin Gage 0.0155 in

Product Description

The VERMONT GAGE 111401550 is a Class ZZ Minus plug pin gage machined from steel and used to perform NoGo inspection checks in precision measurement applications. At 0.0155 inches in diameter and 2 inches in overall length, this pin gage is built for verifying small-bore and fine-tolerance work where dimensional accuracy is critical. The minus tolerance designation means the gage is ground to the lower boundary of the Class ZZ tolerance band, holding a tolerance of 0.0002 inches. Each unit ships with a Certificate of Accuracy traceable to NIST standards, supporting quality-system documentation requirements for calibrated tooling. Machinists, quality technicians, and tool-and-die professionals use this gage in production and inspection environments.

This pin gage is suited for NoGo inspection tasks as well as setting and verifying micrometers, verniers, and other precision measuring devices. Its fine diameter makes it appropriate for inspecting small holes, bores, and slots in precision-machined components across aerospace, medical device, automotive, and general manufacturing applications. The 10 microfinish surface coating supports accurate, repeatable contact with the measurement surface and reduces wear during regular inspection use.

Key Features

• Class ZZ Minus tolerance designation: ground to the lower boundary of the tolerance band at 0.0002 inches
• 0.0155-inch measurement diameter for fine-bore and small-hole inspection
• 2-inch overall length for controlled handling during close-tolerance gaging
• 10 microfinish surface for consistent contact and reduced gage wear
• Includes Certificate of Accuracy with NIST traceability for calibration records
• Steel construction for dimensional stability in production inspection environments

Compatibility

Designed for use as a NoGo inspection gage and for setting micrometers, verniers, and other precision measuring devices where a 0.0155-inch reference diameter is required.

Installation Notes

Pin gages are handled by quality technicians and metrology professionals. Store the gage in its protective sleeve or case when not in use to prevent surface damage and contamination. Clean contact surfaces with a lint-free cloth before use to ensure accurate measurement readings. Do not force the gage into a bore; apply only light, controlled hand pressure to avoid deflection or surface damage.
