Built from steel, this go\/no-go style gage gives machinists, toolmakers, and quality inspectors a fast, reliable method for confirming inside diameter conformance on production parts and assemblies. Class ZZ is the standard tolerance grade for plug gages used in general inspection work where consistent dimensional accuracy is required.\u003c\/p\u003e\n\u003cp\u003eThis plug gage suits shop-floor and inspection-room applications in manufacturing environments where precise hole diameter verification is part of the quality process. It is appropriate for use on drilled, reamed, or bored features in metal components. Typical users include machining shops, tool rooms, and production facilities performing in-process or final inspection checks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.451 inch nominal measurement diameter for precision bore inspection\u003c\/li\u003e\n  \u003cli\u003e0.0002 inch tolerance meets Class ZZ Plus gage standards\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.2 pounds for easy handling at the machine or inspection bench\u003c\/li\u003e\n  \u003cli\u003eSingle-piece package quantity for individual gage acquisition\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 verifying inside diameters at 0.451 inches across a range of machined components and production parts.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled by machinists and quality inspection personnel and require no installation in the traditional sense. Before use, clean the gage and the bore being measured to remove chips, oil, and debris that could affect readings. Do not force the gage into an undersized bore, as this can damage the gage land and compromise calibration. Store the gage in a protective case away from other tooling to prevent surface damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter of Measurement\u003c\/strong\u003e: 0.451 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches\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\u003eGage Class\u003c\/strong\u003e: ZZ Plus\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: 29-451-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51718668353842,"sku":"29-451-2","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/17d21e3b66d450ef5ee4979c30e3b3c7.jpg?v=1788554888","url":"https:\/\/voomisupply.com\/products\/spi-29-451-2-class-zz-plus-plug-gage-0-451-in","provider":"Voomi Supply","version":"1.0","type":"link"}
