It holds a tolerance of 0.0002 inches, making it suitable for precision quality-control work in manufacturing, machining, and mechanical assembly environments. The gage body is constructed from steel for wear resistance and dimensional stability under repeated use. Machinists, quality technicians, and tool-and-die professionals use plug gages like this one to verify that a hole falls within an acceptable size range before a part advances to the next stage of production.\u003c\/p\u003e\n\u003cp\u003eThis gage is applied wherever a 0.88-inch diameter hole must be confirmed to print specification. Typical use cases include incoming inspection of machined components, in-process checks on CNC-milled or drilled parts, and final inspection on production floors. It is equally at home in a job-shop environment or a high-volume manufacturing line. The Class ZZ Plus designation reflects a commercial-grade tolerance class commonly specified for general-purpose inspection work rather than master or reference gage applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.88-inch nominal diameter for go\/no-go hole inspection\u003c\/li\u003e\n  \u003cli\u003e0.0002-inch tolerance for reliable Class ZZ Plus dimensional verification\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides wear resistance and long service life\u003c\/li\u003e\n  \u003cli\u003eCompact form factor at 0.2 pounds for easy single-hand use\u003c\/li\u003e\n  \u003cli\u003eSingle-piece package quantity — ready to deploy individually\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose Class ZZ Plus plug gage for inspecting 0.88-inch nominal diameter bored or drilled holes in steel, aluminum, and other machined materials across standard manufacturing and quality-control applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages require no installation but should be handled and stored according to standard metrology practices. Clean and lightly oil the gage before and after use to prevent corrosion and contamination of the reference surfaces. Always verify the gage itself is within calibration before use; a worn or out-of-tolerance gage produces false acceptance results. Gages should be stored in a protective case away from temperature extremes to maintain dimensional stability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter of Measurement\u003c\/strong\u003e: 0.88 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\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: 29-880-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51715813867826,"sku":"29-880-2","price":16.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3c62e5ae011a096e7053802c973de4b7.jpg?v=1788518658","url":"https:\/\/voomisupply.com\/products\/spi-29-880-2-class-zz-plus-plug-gage-0-88-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
