Vermont Gage 112315590 Class Zz Plus Plug Gage 15.59mm

Product Description

The VERMONT GAGE 112315590 is a Class ZZ Plus plug gage designed for precision dimensional inspection of bored holes and machined features. It measures 15.59 mm in diameter with a tolerance of 0.00508 mm, making it suitable for Go inspection applications where confirming minimum acceptable hole size is critical. Manufactured from tool steel and finished to a 10 micro surface, this gage delivers the dimensional stability and wear resistance required in production and metrology environments. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting quality documentation requirements under ASME B89.1.

This plug gage is used in machine shops, manufacturing facilities, and quality control labs. It is well suited for verifying hole diameter on machined components alongside micrometers, verniers, and other measuring devices. The Go configuration confirms that a hole meets the lower boundary of its tolerance zone, making it a standard tool in first-article inspection, in-process gauging, and final acceptance checks. It is appropriate for both job-shop and production-line environments where ASME B89.1 compliance is required.

Compatibility

Designed for use with standard plug gage handles and compatible with Go inspection setups alongside micrometers, verniers, and other measuring devices as noted in the product specifications.

Installation Notes

Plug gages are handled and used by quality technicians and machinists in inspection environments. Before use, ensure the gage and workpiece are at a stable ambient temperature to minimize thermal expansion error. Clean the gage and hole thoroughly before gauging to prevent false readings and surface damage. Store the gage in its protective case when not in use to preserve the calibrated surface finish.
