The gage measures a nominal diameter of 0.994 inches and holds a tolerance of 0.0002 inches, making it suitable for go\/no-go inspection routines on machined parts. Constructed from steel, it provides the rigidity and wear resistance expected in a production or inspection environment. Machinists, quality technicians, and tool-room professionals use plug gages like this to confirm hole sizes during in-process and final inspection.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is used in manufacturing, machining, and quality control settings where tight-tolerance hole verification is required. It is appropriate for inspecting drilled, reamed, or bored holes in metal, plastic, or composite workpieces. Class ZZ Plus designation indicates the gage conforms to tolerance standards appropriate for general-purpose inspection work. It is suited to both job-shop and production environments where consistent, repeatable measurement of 0.994-inch diameter features is needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal measurement diameter of 0.994 inches for precise bore verification\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus tolerance of 0.0002 inches for general-purpose inspection accuracy\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides durability and dimensional stability during repeated use\u003c\/li\u003e\n  \u003cli\u003eCompact single-unit package suitable for bench, floor, or tool-room use\u003c\/li\u003e\n  \u003cli\u003eTolerance also expressed as 0.0002 mm for dual-unit reference\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 general-purpose go\/no-go inspection of machined bores and holes at a nominal diameter of 0.994 inches.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by quality technicians and machinists and do not require installation in the traditional sense. Before use, clean the gage and the bore being checked to remove chips, coolant, and debris that could affect the reading. Store the gage in its protective case when not in use to prevent nicks or corrosion that would compromise accuracy. Periodic recalibration against a traceable standard is recommended to maintain measurement integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter of Measurement\u003c\/strong\u003e: 0.994 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches (0.0002 mm)\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  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111600\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: 29-994-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51718147440946,"sku":"29-994-1","price":16.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/70c1f68a34a8fccb42c24ab5f31c216e.jpg?v=1788550337","url":"https:\/\/voomisupply.com\/products\/spi-29-994-1-class-zz-plus-plug-gage-0-994-in-dia","provider":"Voomi Supply","version":"1.0","type":"link"}
