Vermont Gage 111310150 Class Zz Plus Plug Gage 0.1015 in

Product Description

The VERMONT GAGE 111310150 is a Class ZZ Plus plug gage machined from tool steel for dimensional go inspection of holes and bores at 0.1015 inches diameter. It carries a tolerance of 0.0002 inches and a 10 microfinish surface finish, delivering the precision required for verifying inside diameters against tight engineering tolerances. Each gage ships with a Certificate of Accuracy traceable to NIST, making it suitable for use in calibrated inspection environments. Machinists, quality technicians, and tool room personnel use this gage to qualify workpieces and to set micrometers, verniers, and other measuring devices to a known reference diameter.

This plug gage is suited for precision inspection work in machine shops, manufacturing cells, and metrology labs handling small-bore components. Its 0.1015 inch diameter places it in the range commonly encountered in precision drilling, reaming, and boring operations. Applications include go-inspection of drilled or reamed holes to confirm the bore is within the minimum acceptable size before assembly. The gage is also used as a setting standard for inside micrometers, bore gages, and similar instruments requiring a reference of known diameter.

Key Features

• Class ZZ Plus tolerance grade: 0.0002 inches, suitable for precision go inspection
• 10 microfinish surface on the gage member for accurate, repeatable contact
• Tool steel construction for hardness and wear resistance in production use
• Certificate of Accuracy with NIST traceability included for calibrated inspection records
• Conforms to ASME B89.1 dimensional standards
• Overall length of 2.0 inches for a secure grip during inspection

Compatibility

Designed for go inspection of holes and bores at 0.1015 inches diameter. Also functions as a setting reference for micrometers, verniers, and other inside measuring devices requiring a traceable diameter standard.

Installation Notes

Plug gages are used by quality technicians and machinists and require no permanent installation. Before use, clean both the gage and the workpiece bore with a lint-free cloth to remove chips, oil, and debris that could affect the measurement. Store the gage in its protective case when not in use to prevent surface damage that would affect tolerance accuracy. Never force a go gage into a bore; if resistance is felt beyond normal slip-fit contact, the bore condition should be investigated before proceeding.
