Built to a 0.788-inch nominal diameter with a tolerance of 0.0002 inches, this gage provides a reliable go\/no-go reference for verifying bore dimensions on machined parts and assemblies. Constructed from steel, it delivers the dimensional stability required for repeat inspection tasks. Machinists, quality technicians, and tool-room professionals use plug gages like this one as a fast, low-variability method for confirming hole size compliance without complex setup.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is suited for use in machine shops, production floors, and quality inspection stations where consistent bore verification is required. It applies to any application calling for a 0.788-inch hole check, including fixture verification, incoming inspection of machined components, and in-process quality control. The Class ZZ Plus designation indicates a commercial-grade tolerance class appropriate for general-purpose inspection work rather than master or reference gage applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.788-inch nominal diameter for precise bore measurement\u003c\/li\u003e\n  \u003cli\u003e0.0002-inch tolerance meets Class ZZ Plus classification requirements\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides dimensional stability and wear resistance\u003c\/li\u003e\n  \u003cli\u003eCompact, single-piece design for fast go\/no-go inspection\u003c\/li\u003e\n  \u003cli\u003eIndividual unit packaging protects the gage surface during storage and transport\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose Class ZZ Plus plug gage for any application requiring inspection of a 0.788-inch nominal diameter bore.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by quality technicians and machinists in accordance with standard metrology practices. Keep the gage surface clean and lightly oiled when not in use to prevent corrosion. Do not force the gage into a bore; excessive insertion pressure can damage both the gage and the workpiece. Store separately from cutting tools and abrasive materials to protect the precision-ground surface.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Class\u003c\/strong\u003e: ZZ Plus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter of Measurement\u003c\/strong\u003e: 0.788 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches (0.0002 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111600\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 29-788-7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51689360064818,"sku":"29-788-7","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2503b037fb6f34e534436e6608f6d067.jpg?v=1788258244","url":"https:\/\/voomisupply.com\/products\/spi-29-788-7-class-zz-plus-plug-gage-0-788-in","provider":"Voomi Supply","version":"1.0","type":"link"}
