It measures hole diameters at 0.282 inches with a tolerance of 0.0002 inches, making it suitable for quality control applications where tight dimensional verification is required. Machined from steel, this gage provides consistent, repeatable results in production and inspection environments. Machinists, toolmakers, and quality control technicians use plug gages like this as a fast, reliable method to confirm hole dimensions meet specification without requiring a full measurement instrument setup.\u003c\/p\u003e\n\u003cp\u003eThe 29-282-1 is used in machine shops, manufacturing facilities, and precision fabrication environments for incoming inspection, in-process checks, and final part verification. It is appropriate for both light production runs and high-volume inspection tasks where speed and accuracy are equally important. The compact, single-ended format makes it easy to handle and store as part of a broader gage set or used as a standalone check for a specific hole diameter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus tolerance grade for general-purpose hole inspection\u003c\/li\u003e\n  \u003cli\u003e0.282 inch nominal diameter for precise dimensional checking\u003c\/li\u003e\n  \u003cli\u003e0.0002 inch tolerance for repeatable go\/no-go verification\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in shop environments\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.2 pounds for easy single-hand use\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 0.282 inch nominal diameter holes in machined components across a wide range of industries and materials.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by machinists and quality control inspectors — no installation in the traditional sense is required. Store the gage in a protective case away from moisture and contaminants to prevent corrosion of the steel surface. Do not force the gage into an undersized hole, as this can damage the gage or the workpiece. Allow the gage to reach ambient shop temperature before use to avoid thermal expansion errors in close-tolerance measurements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter of Measurement\u003c\/strong\u003e: 0.282 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  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 29-282-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51715550773554,"sku":"29-282-1","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/25b7502deb0a8a5961a9fae8d6cc05de.jpg?v=1788515492","url":"https:\/\/voomisupply.com\/products\/spi-29-282-1-class-zz-plus-plug-gage-0-282-in","provider":"Voomi Supply","version":"1.0","type":"link"}
