Vermont Gage 111313050 Class Zz Plus Plug Gage

Product Description

The VERMONT GAGE 111313050 is a Class ZZ Plus plug gage used to verify bore and hole diameters with precision in manufacturing and inspection environments. Machined from tool steel to a 10 microfinish surface quality, this gage measures 0.1305 inches in diameter with a tolerance of 0.0002 inches. At 2.0 inches in overall length, it is sized for handheld use in close-tolerance inspection work. Each unit ships with a Certificate of Accuracy that includes NIST traceability, meeting the documentation requirements of quality management systems. Licensed metrologists, machinists, and quality control technicians are the primary users of this instrument.

This plug gage is suited for go inspection applications across precision machining, toolroom, and production floor environments. It is used to check whether a hole or bore falls within acceptable dimensional limits before assembly or further processing. It is also referenced when calibrating or setting micrometers, verniers, and other measuring devices. The 0.1305-inch diameter targets small-bore applications common in precision component manufacturing, aerospace, and general metalworking. Its compact form fits easily into standard gage blocks and storage setups used in both shop and lab inspection stations.

Key Features

• Class ZZ Plus tolerance grade with 0.0002 inches tolerance for high-accuracy go inspection
• 10 microfinish surface finish on the gage pin for repeatable, wear-resistant contact
• Tool steel construction provides durability in production inspection use
• Includes Certificate of Accuracy with NIST traceability for quality system compliance
• Conforms to ASME B89.1 dimensional standards
• 2.0 inches overall length for comfortable handheld use on small-bore work

Compatibility

Designed for use as a go inspection gage for holes and bores at 0.1305 inches nominal diameter. Also suitable for setting and verifying micrometers, verniers, and other dimensional measuring devices requiring a traceable reference standard.

Installation Notes

Plug gages are handled and used by quality technicians, machinists, and metrologists. Store and handle this gage in a clean, temperature-stable environment to prevent thermal expansion errors and surface contamination. Inspect the gage pin for nicks or wear before each use, and never force the gage into an undersized bore. Follow your facility's calibration interval procedures and retain the NIST-traceable Certificate of Accuracy in your quality records.
