Built from steel, it delivers a tolerance of 0.0002 inches, meeting Class ZZ Plus standards for go\/no-go verification in production and quality-control environments. Machinists, tool-and-die makers, and quality technicians use this gage to confirm that drilled, reamed, or bored holes fall within specified limits before parts move to the next stage of manufacture or assembly.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is suited for use on the shop floor or in inspection rooms where consistent, repeatable measurement of small-diameter holes is required. It is appropriate for both low-volume job shops and higher-volume production lines that need a reliable, simple tool for pass\/fail hole verification. The 0.569-inch nominal diameter targets a specific bore size common in precision machined components across general metalworking, tooling, and mechanical assembly applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus tolerance rating at 0.0002 inches for precise go\/no-go inspection\u003c\/li\u003e\n  \u003cli\u003eNominal measurement diameter of 0.569 inches\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and wear resistance in production environments\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.2 pounds for easy single-hand use during inspection\u003c\/li\u003e\n  \u003cli\u003eSingle-piece package quantity supports individual replacement or tooling additions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct addition to Class ZZ plug gage sets used for go\/no-go inspection of 0.569-inch nominal diameter cylindrical bores in precision machining and quality-control applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by machinists or quality-control technicians — no power tools or trade licensing is required, but proper gage-handling procedures should be followed to preserve accuracy. Clean the gage and the bore being inspected before use to prevent false readings from chips, coolant, or debris. Store the gage in its protective case when not in use to prevent corrosion and surface damage that can affect tolerance accuracy. Do not force the gage into a bore; resistance indicates the bore is out of tolerance on the small side.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 0.569 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\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: 29-569-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51723251646770,"sku":"29-569-1","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fc083a0141fd34c661a2ffe9339c5563.jpg?v=1788602288","url":"https:\/\/voomisupply.com\/products\/spi-29-569-1-class-zz-plus-plug-gage-0-569-in","provider":"Voomi Supply","version":"1.0","type":"link"}
