It measures internal diameters at a nominal size of 0.945 inches with a tolerance of 0.0002 inches, making it suitable for go\/no-go inspection workflows where tight dimensional control is required. Constructed from steel, this gage provides the durability and dimensional stability expected in production and inspection applications. It is installed and used by machinists, quality technicians, and toolroom professionals.\u003c\/p\u003e\u003cp\u003eThis plug gage is used to verify the diameter of drilled, bored, or reamed holes in manufacturing and inspection settings. Class ZZ Plus gages are typically applied in less critical tolerance applications where a cost-effective, reliable inspection tool is needed. The 29-945-3 is suited for both shop-floor spot checks and more controlled inspection room use, wherever a 0.945-inch bore diameter must be confirmed to specification.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNominal measurement diameter of 0.945 inches for precise bore inspection\u003c\/li\u003e\n\u003cli\u003eClass ZZ Plus tolerance rating of 0.0002 inches ensures reliable go\/no-go gauging\u003c\/li\u003e\n\u003cli\u003eSteel construction provides durability and dimensional stability during repeated use\u003c\/li\u003e\n\u003cli\u003eCompact and lightweight at 0.2 pounds for easy handling during inspection tasks\u003c\/li\u003e\n\u003cli\u003eSingle-piece package quantity for individual toolroom or inspection station use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit Class ZZ Plus plug gage for inspecting internal bores with a nominal diameter of 0.945 inches in standard manufacturing and quality control applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePlug gages are used by machinists and quality control technicians and require no permanent installation. Before use, ensure the gage and workpiece are at the same ambient temperature to avoid thermal expansion errors. Handle the gage carefully to prevent surface damage that could affect measurement accuracy. Store in a protective case when not in use to maintain calibration integrity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 0.945 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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 29-945-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51689290793266,"sku":"29-945-3","price":16.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f34f47dc38ef5d2bbdd71a319344e5e2.jpg?v=1788256914","url":"https:\/\/voomisupply.com\/products\/spi-29-945-3-class-zz-plus-plug-gage-0-945-in","provider":"Voomi Supply","version":"1.0","type":"link"}
