It is designed for go\/no-go inspection workflows, providing a fast, reliable method to confirm whether a bore falls within acceptable tolerance. The gage holds a tolerance of 0.0002 inches, making it suitable for quality control in machine shops, toolrooms, and production environments. It is typically used by machinists, quality technicians, and tool-and-die professionals who require traceable dimensional verification on small-diameter features.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is suited for inspecting small bores in manufactured components across metalworking, precision machining, and light manufacturing applications. The 0.023-inch nominal diameter targets very fine bores commonly found in fuel system components, instrument housings, and precision mechanical assemblies. It is used at receiving inspection stations, on the shop floor, or in dedicated quality labs where consistent hole-size verification is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal measurement diameter of 0.023 inches for small-bore inspection\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus tolerance rating of 0.0002 inches for reliable go\/no-go checks\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and dimensional stability during repeated use\u003c\/li\u003e\n  \u003cli\u003eCompact, single-piece form factor suitable for bench or in-process inspection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style precision inspection gage for use with standard go\/no-go gage handle sets accepting pin gages at the 0.023-inch nominal diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by quality technicians and machinists; no power source or special tooling is required for operation. Keep the gage clean and lightly oiled when not in use to prevent corrosion and maintain dimensional accuracy. Do not force the gage into a bore, as this can damage both the gage and the workpiece. Store separately from other metal tooling to avoid nicks or surface damage that would affect accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.023 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches\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\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: 29-023-9\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51707711652146,"sku":"29-023-9","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ed0e96aed9efd51bad712d1e6edb4049.jpg?v=1788441774","url":"https:\/\/voomisupply.com\/products\/spi-29-023-9-class-zz-plus-plug-gage-0-023-in","provider":"Voomi Supply","version":"1.0","type":"link"}
