It measures a nominal diameter of 0.046 inches with a tolerance of 0.0002 inches, making it suitable for tight-tolerance quality control work in machine shops, tool rooms, and production environments. Constructed from steel, this gage provides the dimensional stability required for repeatable measurement. Machinists, quality technicians, and inspection personnel use plug gages like this to verify that drilled, reamed, or punched holes fall within specified dimensional limits.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for inspecting small-diameter features in precision-machined components, sheet metal parts, and fabricated assemblies. The Class ZZ Plus designation indicates a commercial-grade tolerance class appropriate for general inspection and production-floor go\/no-go checks. It is commonly used in metalworking, aerospace, automotive, and industrial manufacturing settings where hole diameter verification is part of a standard quality process.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.046-inch nominal diameter for inspection of small bores and holes\u003c\/li\u003e\n  \u003cli\u003e0.0002-inch tolerance meeting Class ZZ Plus standards\u003c\/li\u003e\n  \u003cli\u003eSteel construction for dimensional stability and durability\u003c\/li\u003e\n  \u003cli\u003eGo\/no-go design enables fast pass-fail inspection on the production floor\u003c\/li\u003e\n  \u003cli\u003eCompact, single-piece form for easy handling and storage\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style plug gage for go\/no-go inspection applications requiring a 0.046-inch nominal diameter check at Class ZZ Plus tolerance.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are used by machinists and quality inspection personnel and do not require installation in the traditional sense. Before use, clean the gage and the bore being measured to remove chips, oil, and debris that could affect readings. Do not force the gage through a hole; excessive insertion force can damage the gage or the workpiece and will produce unreliable results. Store plug gages in a protective case away from other tooling to prevent wear and corrosion that would compromise accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter of Measurement\u003c\/strong\u003e: 0.046 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 (mm)\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\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\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: 29-046-0\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51692482887986,"sku":"29-046-0","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c93e0e7559ec14022398cd8826166048.jpg?v=1788298211","url":"https:\/\/voomisupply.com\/products\/spi-29-046-0-class-zz-plus-plug-gage-0-046-in","provider":"Voomi Supply","version":"1.0","type":"link"}
