It measures a nominal diameter of 0.71 inches with a tolerance of 0.0002 inches, making it suitable for go\/no-go verification where tight dimensional accuracy is required. Constructed from steel, the gage resists wear under repeated use in shop environments. Machinists, toolroom technicians, and quality inspectors use this type of gage to verify that drilled, reamed, or bored holes fall within specified tolerance limits before parts move to the next stage of production.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is suited for use in production and toolroom settings where hole diameter conformance must be confirmed quickly and reliably. It is appropriate for both incoming inspection of raw stock and in-process checks on machined components. The 0.71-inch nominal size covers a common bore dimension found in general mechanical assemblies. Class ZZ Plus designation indicates a standard tolerance grade used for checking work piece tolerances in production inspection rather than master or reference gage applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.71-inch nominal measurement diameter for precise bore inspection\u003c\/li\u003e\n  \u003cli\u003e0.0002-inch tolerance for reliable go\/no-go dimensional verification\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and resistance to wear in shop environments\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus tolerance grade suitable for production inspection use\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.2 pounds for easy single-handed operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Class ZZ Plus plug gage for production inspection of 0.71-inch nominal diameter bores and holes in general machined components.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by machinists, quality technicians, and toolroom personnel rather than installed in a system. Before use, clean the gage and the bore being checked to remove chips, coolant, and debris that could affect readings. Do not force the gage into an undersized hole, as this can damage the gage surface and compromise accuracy. Store the gage in its protective case when not in use to prevent nicks, corrosion, and dimensional drift.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.71 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance (metric)\u003c\/strong\u003e: 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\u003eGage Class\u003c\/strong\u003e: ZZ Plus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 29-710-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51709682516274,"sku":"29-710-1","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a6e2e87a22b43077e5ef5c00b1bd4b8e.jpg?v=1788459102","url":"https:\/\/voomisupply.com\/products\/spi-29-710-1-class-zz-plus-plug-gage-0-71-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
