Manufactured from steel, this gage checks a nominal diameter of 0.012 inches with a tolerance of 0.0002 inches, making it suited for precision inspection work in manufacturing, toolroom, and quality-control environments. Class ZZ Plus gages meet established go\/no-go inspection standards and are a standard tool for machinists, metrologists, and quality technicians who require reliable, repeatable measurement of small-diameter features.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is intended for use in precision measurement applications where small-bore diameter verification is required. It is commonly used in machining shops, toolrooms, and production inspection stations to confirm that drilled, reamed, or machined holes fall within specified dimensional tolerances. The 0.012-inch diameter makes it appropriate for inspecting very fine bores typical in precision components, nozzles, or small-diameter orifice applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal measurement diameter of 0.012 inches for fine-bore inspection\u003c\/li\u003e\n  \u003cli\u003eTolerance of 0.0002 inches for precise go\/no-go verification\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus classification meets standard inspection-grade requirements\u003c\/li\u003e\n  \u003cli\u003eCompact, single-unit package suitable for individual toolroom use\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 with any go\/no-go inspection system or gage handle that accepts 0.012-inch diameter plug gage wire inserts.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages should be handled with clean, dry hands or inspection gloves to prevent corrosion from skin oils. Store in a protective case away from other tooling to avoid damage to the gage surface. Before use, confirm the gage and workpiece are at the same ambient temperature to avoid thermal expansion errors. Calibration and use should follow applicable ASME or ISO dimensional measurement standards as required by your quality program.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter of Measurement\u003c\/strong\u003e: 0.012 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\u003eGage Class\u003c\/strong\u003e: ZZ Plus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\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: 29-012-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51701026062642,"sku":"29-012-2","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/45f76e29f0176b023a423acb5da2d26d.jpg?v=1788396984","url":"https:\/\/voomisupply.com\/products\/spi-29-012-2-class-zz-plus-plug-gage-0-012-in","provider":"Voomi Supply","version":"1.0","type":"link"}
