Built to a nominal diameter of 0.768 inches with a tolerance of 0.0002 inches, this gage provides reliable go\/no-go verification for drilled, reamed, or bored features. The steel construction delivers the hardness and dimensional stability required for repeated use in shop-floor and inspection-room environments. Machinists, toolmakers, and quality technicians use plug gages like this one to confirm that a hole falls within the specified size range before a part moves to the next stage of production.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for use in manufacturing facilities, machine shops, and inspection departments where tight-tolerance hole verification is required. It is appropriate for both production-line spot checks and incoming or final inspection workflows. The 0.768-inch nominal size makes it a practical choice for applications involving close-tolerance bores in ferrous and non-ferrous components. A single gage is supplied per package, making it easy to stock as a replacement or supplement to an existing gage set.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal measurement diameter of 0.768 inches for direct hole-size verification\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus tolerance rating of 0.0002 inches for precision go\/no-go inspection\u003c\/li\u003e\n  \u003cli\u003eSteel construction for hardness, wear resistance, and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eSingle-piece package suitable for individual replacement or set expansion\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.2 pounds for easy handling during inspection\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 use in general precision inspection applications requiring 0.768-inch nominal bore verification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by machinists, toolmakers, and quality-control inspectors — no power tools or energy isolation is required. Keep gage surfaces clean and lightly oiled when not in use to prevent corrosion. Do not force the gage into a bore; if resistance is felt, the hole is undersized and should be re-inspected before proceeding. Store in a protective case away from temperature extremes to maintain calibration integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.768 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: 29-768-9\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51691455643954,"sku":"29-768-9","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5f32656ea9f2742d45aed1a48f550e30_c9aed14b-c1fb-4928-bfb9-ad69541ecd15.jpg?v=1788285303","url":"https:\/\/voomisupply.com\/products\/spi-29-768-9-class-zz-plus-plug-gage-0-768-in","provider":"Voomi Supply","version":"1.0","type":"link"}
