Vermont Gage 111299400 Class Zz Minus Plug Pin Gage

Product Description

The VERMONT GAGE 111299400 is a Class ZZ Minus plug pin gage with a 0.9940-inch measurement diameter, designed for NoGo inspection applications in dimensional quality control work. Built from steel with a 10 microinch surface finish, it provides a tolerance of 0.0002 inches and ships with a Certificate of Accuracy traceable to NIST standards. This type of gage is used by machinists, quality technicians, and metrology professionals to verify that bores and holes do not exceed a specified maximum limit. The 2-inch overall length offers a comfortable handling profile for bench and floor inspection use.

This plug pin gage is suited for use in manufacturing environments where go/no-go inspection protocols are required on machined bores, drilled holes, or reamed features. It is also appropriate for setting and verifying micrometers, verniers, and other dimensional measuring devices. Applications span precision machining shops, aerospace, automotive, and general metalworking environments where strict dimensional tolerances must be confirmed before parts advance through production or ship to customers.

Key Features

• Class ZZ Minus tolerance class — designed for NoGo inspection use
• 0.0002-inch tolerance for reliable dimensional verification
• Steel construction with 10 microinch surface finish for durability and accuracy
• NIST-traceable Certificate of Accuracy included with each gage
• Compatible with micrometers, verniers, and other calibrated measuring devices
• 2-inch overall length for easy handling during inspection routines

Compatibility

Designed as an OEM-style plug pin gage for use in NoGo bore inspection applications and for setting micrometers, verniers, and other dimensional measuring instruments in trade and manufacturing environments.

Installation Notes

Handle pin gages with clean, dry hands or cotton gloves to prevent corrosion from skin oils. Store in the provided case or protective sleeve when not in use. Do not force the gage into a feature — excessive insertion force can damage both the gage and the workpiece. Calibration intervals should follow your facility's quality management procedures or applicable standards such as ASME B89.1.5.
