Vermont Gage 111173700 Class Zz Plus Plug Gage 0.737 in

Product Description

The VERMONT GAGE 111173700 is a Class ZZ Plus plug gage designed for precise go-type dimensional inspection of bored holes and machined features. Built from tool steel with a 10 microinch surface finish, this gage provides a measurement diameter of 0.737 inches with a tolerance of 0.0002 inches. At 2.0 inches overall length, it is sized for comfortable single-hand use on the shop floor or inspection bench. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting ASME B89.1 standards. Machinists, quality technicians, and precision metrology professionals use this gage to verify conformance on production parts.

This plug gage is suited for go inspection applications in machine shops, toolrooms, and quality control environments. It is used to verify hole diameters on machined components as part of a go/no-go inspection routine. The 0.737-inch diameter makes it applicable to a range of medium-bore features in both prototype and production settings. It is also appropriate for setting and calibrating micrometers, verniers, and other measuring devices requiring a known reference standard.

Key Features

• Class ZZ Plus tolerance grade with 0.0002-inch tolerance for high-accuracy go inspection
• 10 microinch surface finish for consistent, repeatable gage contact
• Tool steel construction for durability and wear resistance in production environments
• Includes Certificate of Accuracy with NIST traceability
• Meets ASME B89.1 dimensional gage standards
• 2.0-inch overall length for convenient bench and in-line use

Compatibility

Designed for go inspection use with bored holes and machined features at 0.737 inches diameter. Also suitable for setting micrometers, verniers, and other precision measuring devices requiring a traceable reference standard.

Installation Notes

Handle with clean, dry hands or lint-free gloves to prevent corrosion from skin oils. Store in a protective case away from temperature extremes to maintain calibration integrity. Do not force the gage into a feature; if resistance is felt, the bore is undersize and the part should be re-evaluated. Periodic recalibration against a traceable standard is recommended per shop quality control procedures.
