Vermont Gage 112211520 Class Zz Minus Plug Pin Gage 11.52mm

Product Description

The VERMONT GAGE 112211520 is a Class ZZ minus plug pin gage machined to a 11.52 mm diameter with a tolerance of 0.00508 mm. It is designed for NoGo go/no-go inspection applications and is also suitable for setting micrometers, verniers, and other precision measuring devices. Constructed from steel with a 10 microfinish surface coating, this pin gage delivers the dimensional accuracy required for quality control checks on the shop floor or in a metrology lab. Each unit ships with a Certificate of Accuracy that includes NIST traceability, confirming the gage has been verified against national measurement standards. Machinists, quality technicians, and metrology professionals are the primary users of this tool.

This pin gage is suited for dimensional inspection work in manufacturing, machining, and fabrication environments where tight bore or hole tolerances must be verified. The 11.52 mm diameter and Class ZZ minus classification make it appropriate for NoGo inspection checks where a part must reject the gage to pass. It is also used to calibrate and verify micrometers, verniers, and other hand-measuring instruments prior to use. The overall length of 2 inches provides a comfortable, stable grip during single-hand inspection operations.

Key Features

• Class ZZ minus tolerance classification: 0.00508 mm tolerance for NoGo inspection work
• 11.52 mm measurement diameter for precise bore and hole verification
• Steel construction with 10 microfinish surface coating for dimensional stability and smooth insertion
• NIST-traceable Certificate of Accuracy included with each unit
• 2-inch overall length for single-hand use during inspection
• Compatible with setting micrometers, verniers, and other measuring devices

Compatibility

Designed for NoGo inspection applications and for setting micrometers, verniers, and other precision measuring devices where an 11.52 mm reference diameter is required.

Installation Notes

Plug pin gages are handled and stored by quality technicians and metrology personnel. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the steel surface. Do not force the gage into a bore; controlled hand pressure is the correct insertion method. Store in the original case or protective sleeve to avoid contact damage to the finished surface.
