Vermont Gage 112315170 Class Zz Plus Plug Gage 15.17 Mm

Product Description

The VERMONT GAGE 112315170 is a Class ZZ Plus plug gage designed for go inspection of bored holes, machined bores, and precision-fitted openings. It measures 15.17 mm in diameter with a tolerance of 0.00508 mm, making it suitable for applications that demand tight dimensional verification. Manufactured from tool steel with a 10 micro coating finish, the gage delivers consistent, repeatable readings across high-volume inspection cycles. A Certificate of Accuracy with NIST traceability is included, supporting documentation requirements in quality-controlled environments. Machinists, tool room technicians, and quality control inspectors are the primary users of this instrument.

This plug gage is used in manufacturing and inspection settings where bore diameter must be verified to ASME B89.1 standards. Typical applications include go inspection of precision-machined components, setting and verifying micrometers, verniers, and other measuring devices. It fits into standard gage handle holders appropriate for the 15.17 mm diameter range and is suited for both production floor spot-checks and formal dimensional inspection records. The included NIST-traceable certificate makes it compatible with ISO 9001 and AS9100 quality management documentation requirements.

Compatibility

Designed for go inspection use with micrometers, verniers, and other precision measuring devices requiring a 15.17 mm reference diameter plug gage per ASME B89.1.

Installation Notes

Plug gages are handled and used by qualified inspection or tool room personnel. Clean the gage and bore thoroughly before use to prevent debris from affecting measurement accuracy. Store the gage in its protective case away from temperature extremes, as thermal expansion can affect dimensional readings. Do not force the gage into an undersized bore, as this can cause damage to both the gage and the workpiece.
