Built from steel, this go\/no-go style gage gives machinists, toolmakers, and quality control technicians a fast, reliable method for checking bore dimensions on production and inspection work. Class ZZ Plus gages meet standard tolerance requirements for general-purpose dimensional inspection and are a staple in machine shops, fabrication facilities, and manufacturing QC departments.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is suited for inspecting drilled, reamed, or bored holes where a nominal diameter of 0.286 inches must be confirmed within tight tolerance. It is appropriate for use on production floors, inspection benches, and incoming material checks. Technicians use this gage as part of standard go\/no-go inspection routines to confirm that workpiece holes fall within acceptable dimensional limits before assembly or further machining operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal measurement diameter of 0.286 inches for precise hole inspection\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus tolerance rating of 0.0002 inches suits general-purpose production inspection\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides durability and wear resistance in shop environments\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.2 pounds for easy single-hand use\u003c\/li\u003e\n  \u003cli\u003eGo\/no-go style enables fast pass-fail inspection without measurement calculation\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 inspection of 0.286-inch nominal diameter bores in machined components across a range of materials and industries.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by machinists, toolmakers, and quality inspectors — no installation in the traditional sense is required. Store the gage in a protective case away from moisture and abrasive surfaces to preserve the ground steel finish. Before use, clean both the gage and the workpiece bore to remove chips, coolant, and debris that could cause false readings or accelerate wear. Never force the gage into an undersized hole; apply only light, consistent hand pressure to avoid damaging the gage surface.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Class\u003c\/strong\u003e: ZZ Plus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.286 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches\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: 29-286-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51699729629490,"sku":"29-286-2","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/35bb7e18772c5f54499849098a748972.jpg?v=1788379969","url":"https:\/\/voomisupply.com\/products\/spi-29-286-2-class-zz-plus-plug-gage-0-286-in","provider":"Voomi Supply","version":"1.0","type":"link"}
