Vermont Gage 112211240 Class Zz Minus Plug Pin Gage 11.24mm

Product Description

The VERMONT GAGE 112211240 is a Class ZZ minus plug pin gage machined from steel and sized to 11.24 mm diameter. It is designed for NoGo inspection work, where a controlled minus tolerance confirms that a hole or bore does not exceed the upper limit of its tolerance range. The gage carries a tolerance of 0.00508 mm and features a 10 microfinish surface coating for consistent, repeatable contact. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting documentation requirements for calibrated inspection tools. Machinists, quality technicians, and tool-room personnel use this gage in go/nogo inspection routines alongside micrometers, verniers, and other precision measuring devices.

This pin gage is used in dimensional inspection of drilled, reamed, or bored holes in manufacturing and machining environments. It suits both job-shop and production floor applications where hole-size verification is required before assembly or final inspection. At 2 inches overall length and 0.09 pounds, it is compact enough for bench work and easy to handle during repetitive checks. The 10 microfinish surface ensures accurate seating in the bore without introducing measurement error from surface irregularity.

Key Features

• Class ZZ minus tolerance for NoGo inspection of 11.24 mm diameter holes
• Tolerance of 0.00508 mm for precise dimensional verification
• 10 microfinish surface coating for consistent bore contact
• Steel construction for durability in production and tool-room use
• Certificate of Accuracy included with NIST traceability
• Compact 2-inch overall length for easy single-hand use

Compatibility

Designed for use in NoGo inspection routines and as a setting reference for micrometers, verniers, and other precision measuring devices requiring an 11.24 mm diameter plug gage.

Installation Notes

This gage is handled and used by quality technicians and machinists during inspection procedures, not installed in a system. Clean the gage and the bore thoroughly before use to prevent debris from affecting measurement results. Store the gage in its protective case when not in use to preserve the surface finish and dimensional integrity. Never force the gage into a bore; consistent insertion force is required for reliable go/nogo results.
