Vermont Gage 112313390 Class Zz Plus Plug Gage 13.39 Mm

Product Description

The VERMONT GAGE 112313390 is a Class ZZ Plus plug gage designed for go inspection of bored, reamed, or drilled holes with a nominal diameter of 13.39 mm. Manufactured from tool steel with a 10 micro finish coating, this gage holds a tolerance of 0.00508 mm, making it suitable for precision dimensional verification in production and quality-control environments. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting documented inspection records. Metrology technicians, machinists, and quality-assurance professionals use this gage to confirm that a hole meets its lower tolerance limit before the part advances to the next stage of production.

This plug gage is used in go inspection applications where hole diameter conformance must be verified quickly and consistently. It is compatible with standard gage handle systems and works alongside set micrometers, verniers, and other measuring devices for comparative measurement tasks. Typical install scenarios include incoming inspection stations, in-process machining cells, and final inspection benches in both job-shop and high-volume manufacturing settings. The 2.0000 inch overall length suits a wide range of workpiece thicknesses and fixturing setups.

Compatibility

Designed for go inspection use with standard plug gage handles and measuring setups including set micrometers and verniers. Intended for holes with a nominal diameter of 13.39 mm.

Installation Notes

Plug gages should be handled by metrology or quality-control personnel trained in gage use and care. Always clean the gage and workpiece hole before use to prevent contamination from chips, coolant, or debris that could cause false readings or damage the gage surface. Store in a protective case when not in use and allow the gage to reach ambient temperature before taking measurements to avoid thermal expansion errors. Periodic recalibration against a traceable standard is recommended to maintain measurement integrity.
