It measures hole diameters at a nominal size of 0.705 inches with a tolerance of 0.0002 inches, providing a reliable reference for checking whether a finished bore meets print specification. Machined from steel, this gage delivers the hardness and wear resistance required for repeated use in production or inspection environments. Metrology technicians, machinists, and quality control inspectors use plug gages like this to verify conformance quickly without requiring a CMM or indicating bore gage.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is suited for use in machine shops, toolrooms, and manufacturing facilities where hole tolerances must be verified during or after machining operations. It is appropriate for both incoming inspection of purchased parts and in-process checks on milled, turned, or ground bores. The compact single-end or double-end format fits standard gage handle sets, making it easy to integrate into an existing inspection workflow. Residential or light-trade use is uncommon; this is primarily a precision manufacturing and metrology tool.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal diameter of 0.705 inches for direct hole-size verification\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus tolerance of 0.0002 inches for reliable dimensional acceptance\u003c\/li\u003e\n  \u003cli\u003eSteel construction for hardness and extended service life in production environments\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.2 pounds, easy to handle during high-volume inspection tasks\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard gage handle sets used in toolroom and shop-floor inspection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use plug gage for any application requiring inspection of a 0.705-inch nominal diameter bore to Class ZZ Plus standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages should be handled with clean, dry hands or lint-free gloves to prevent corrosion from skin oils. Before use, wipe the gage clean and verify there is no visible wear or damage to the gage surface. Apply the gage at room temperature whenever possible, as thermal expansion of the part or gage can affect readings. Store in a protective case away from abrasive materials when not in use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.705 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Class\u003c\/strong\u003e: ZZ Plus\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\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: 29-705-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51706957496626,"sku":"29-705-1","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ed4b13e49f344105cc1991988e912922.jpg?v=1788437635","url":"https:\/\/voomisupply.com\/products\/spi-29-705-1-class-zz-plus-plug-gage-0-705-in","provider":"Voomi Supply","version":"1.0","type":"link"}
