Vermont Gage 1.3086 Plus Class Zz Plus Plug Gage 1.3086 in

Product Description

The VERMONT GAGE 1.3086 PLUS is a Class ZZ Plus plug gage used to verify bore and hole dimensions in machined parts. It provides a go/no-go tolerance check at a nominal diameter of 1.3086 inches, confirming whether a hole meets the specified size requirement. Class ZZ Plus gages are manufactured to tighter tolerances than standard Class ZZ, making them appropriate for quality control inspection in precision machining, metalworking, and industrial manufacturing environments. The handle is sold separately and must be ordered independently. Machinists, quality control inspectors, and toolroom technicians are the typical end users.

This plug gage is suited for incoming inspection, in-process checks, and final inspection of bored, drilled, or reamed holes in production and job-shop environments. It is used wherever a 1.3086-inch nominal hole dimension must be verified against a defined tolerance. Applications span general manufacturing, aerospace fabrication, and precision mechanical assembly. Because the handle is sold separately, users should verify handle compatibility with the gage blank diameter before ordering.

Key Features

• Class ZZ Plus tolerance class for tighter accuracy than standard Class ZZ gages
• Nominal measurement diameter of 1.3086 inches for precise hole verification
• Go/no-go design enables fast, repeatable pass-fail inspection
• Handle sold separately, allowing selection of the appropriate handle for the application
• Single gage member per package — order quantity of one

Compatibility

Designed as a replacement or supplemental Class ZZ Plus plug gage member for use in standard gage handle systems where the handle accepts a 1.3086-inch gage blank. Handle not included.

Installation Notes

Plug gages should be installed and used by qualified machinists or quality control personnel familiar with ASME B89 gage standards. Before use, confirm the gage handle is compatible with the gage blank diameter and that the gage and workpiece are at the same ambient temperature to avoid thermal expansion errors. Clean the gage and the bore before each measurement. Never force a plug gage into an undersized hole, as this can damage the gage surface and compromise calibration.
