Vermont Gage 112316130 Class Zz Plus Plug Gage 16.13mm

Product Description

The VERMONT GAGE 112316130 is a Class ZZ Plus plug gage manufactured from tool steel for dimensional inspection of bored holes, machined bores, and precision-fitted features. It is designed to verify that a hole diameter meets the minimum acceptable size for a Go inspection — confirming a workpiece will accept a mating part. The gage measures 16.13 mm in diameter with a tolerance of 0.00508 mm (0.005 mm), providing the close tolerance performance required for quality control work in machining, toolroom, and metrology environments. Overall length is 2.0000 inches. A Certificate of Accuracy with NIST Traceability is included, supporting documentation requirements in calibrated inspection settings.

This plug gage is used in Go inspection applications where a machinist, quality technician, or metrologist needs to confirm a hole falls within the acceptable size range. Typical use includes verifying drilled, reamed, or bored holes on the shop floor or in the inspection room. It is also suitable for setting micrometers, verniers, and other comparative measuring devices requiring a known reference diameter. The 16.13 mm size fits common metric bore specifications found in general manufacturing and precision machining operations.

Key Features

• Class ZZ Plus tolerance grade for Go inspection verification
• 16.13 mm diameter with 0.00508 mm tolerance for precise dimensional control
• Tool steel construction for wear resistance and dimensional stability
• 10 Micro coating finish for consistent surface quality
• Meets ASME B89.1 standard for dimensional gaging
• Includes Certificate of Accuracy with NIST Traceability for calibration documentation

Compatibility

Designed for Go inspection of 16.13 mm diameter bored or machined holes. Also suitable for use as a setting reference with micrometers, verniers, and other precision measuring devices where a known metric diameter reference is required.

Installation Notes

Plug gages are handled and used by quality technicians, machinists, and metrologists — no power source or fastener installation is required. Store the gage in its case when not in use to prevent nicking the gaging surface. Apply a light coat of instrument oil before storage to prevent corrosion on the tool steel surface. Never force the gage into a hole; resistance indicates the bore is undersized and should be evaluated before proceeding.
