Built from steel, it delivers a tolerance of 0.0002 inches, meeting the dimensional verification requirements typical of precision machining and inspection environments. Class ZZ Plus is a widely recognized tolerance class for plain plug gages used in go\/no-go inspection workflows. Machinists, quality control technicians, and tool room personnel use this gage to verify bore conformance during production and incoming inspection.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is suited for inspection of precision-machined components where tight hole tolerances must be confirmed before assembly. It fits standard hand-held inspection use and is appropriate for both floor-level production checks and formal inspection bench setups. The 0.396-inch nominal diameter targets a specific bore size common in mechanical component manufacturing. At 0.2 pounds, it is lightweight and easy to handle during repetitive measurement tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal measurement diameter of 0.396 inches for precise bore verification\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus tolerance rating at 0.0002 inches for dimensional accuracy\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and resistance to wear during repeated use\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.2 pounds for comfortable single-hand operation\u003c\/li\u003e\n  \u003cli\u003eSuitable for go\/no-go inspection procedures in production and QC environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or equivalent plug gage for use in any standard plain plug gage application requiring a 0.396-inch nominal bore diameter and Class ZZ Plus tolerance classification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by quality control technicians and machinists; no installation in a mechanical system is required. Before use, clean the gage and the bore being checked to remove chips, coolant, and debris that could affect measurement accuracy. Do not force the gage into the bore, as this can damage the gage surface and compromise future readings. Store the gage in its protective case when not in use to prevent wear and corrosion.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 0.396 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\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\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: 29-396-9\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51703603396914,"sku":"29-396-9","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b62d4e90596232b21a6667ece3021539.jpg?v=1788417552","url":"https:\/\/voomisupply.com\/products\/spi-29-396-9-class-zz-plus-plug-gage-0-396-in","provider":"Voomi Supply","version":"1.0","type":"link"}
