Vermont Gage 112101380 Class Zz Plus Plug Gage 1.38 Mm

Product Description

The VERMONT GAGE 112101380 is a Class ZZ Plus plug gage designed for precision dimensional inspection of small bores and holes. It measures 1.38 mm in diameter with a tolerance of 0.00508 mm, making it suitable for high-accuracy go inspection tasks. Machined from tool steel and finished to a 10 microfinish surface quality, this gage delivers consistent, repeatable results. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting ASME B89.1 standards. Machinists, quality technicians, and metrology professionals use this type of gage to verify hole sizes in production and inspection environments.

This plug gage is used in shop-floor and lab settings where precise bore verification is required. It is suited for go inspection applications and can also be used to set and verify micrometers, verniers, and other measuring devices. The compact form factor and 2.0-inch overall length make it easy to handle during routine inspection tasks on small-diameter features in precision machined components.
