Vermont Gage 111154400 Class Zz Plus Plug Gage 0.544 in

Product Description

The VERMONT GAGE 111154400 is a Class ZZ Plus plug gage machined from tool steel for precision bore and hole inspection. It measures 0.544 inches in diameter with a tolerance of 0.0002 inches and a 10 microinch surface finish, delivering the dimensional accuracy required for reliable go inspection work. At 2.0 inches in overall length, the gage is sized for straightforward handling during bench or floor inspection tasks. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting quality documentation requirements in regulated manufacturing and metrology environments. Machinists, toolroom technicians, and quality control inspectors use this gage to verify hole diameters against nominal specifications.

This plug gage is suited for go inspection of bored, drilled, and reamed holes at the 0.544-inch nominal size. It is also used to set and verify micrometers, vernier calipers, and other comparative measuring devices. Applications span general metalworking, tool and die, aerospace component inspection, and any production environment where ASME B89.1 dimensional standards must be met. The 10 microinch finish on the gage member ensures minimal wear on precision gauging surfaces during repeated use.

Compatibility

Designed for go inspection of holes at 0.544 inches nominal diameter and for use as a setting standard with micrometers, vernier calipers, and other precision measuring devices per ASME B89.1.

Installation Notes

This gage is handled by quality control technicians and toolroom personnel, not installed in a mechanical system. Store the gage in its protective case when not in use to prevent surface damage. Clean the gage member before each use to remove chips, oils, or debris that could affect measurement accuracy. Never force the gage into an undersized hole, as this will damage both the gage and the workpiece.
