At 0.277 inches in diameter with a tolerance of 0.0002 inches, this gage provides a reliable go\/no-go reference for quality control in machining, fabrication, and inspection environments. Class ZZ is the standard tolerance class for plug gages used in general-purpose inspection work. Machinists, toolmakers, and quality technicians use this type of gage to confirm dimensional conformance on production parts and assemblies without relying on variable measuring instruments.\u003c\/p\u003e\n\u003cp\u003eThis plug pin gage is suited for shop-floor and inspection-room use wherever a 0.277-inch bore or hole must be verified against a minimum size specification. It is appropriate for residential, commercial, and industrial manufacturing environments. Typical applications include checking drilled, reamed, or bored holes in metal, plastic, or composite workpieces as part of incoming inspection, in-process quality checks, or final acceptance testing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ minus tolerance class for general-purpose hole inspection\u003c\/li\u003e\n  \u003cli\u003e0.277-inch nominal diameter for direct go\/no-go size verification\u003c\/li\u003e\n  \u003cli\u003eTolerance of 0.0002 inches ensures consistent, repeatable measurement reference\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability under regular shop use\u003c\/li\u003e\n  \u003cli\u003eCompact single-piece design suitable for hand-held inspection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Class ZZ minus plug pin gage for general-purpose bore and hole inspection at a 0.277-inch nominal diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug pin gages are used by machinists and quality inspectors and require no installation in the traditional sense. Ensure the gage and workpiece are clean and free of chips, coolant, or debris before use to prevent false readings or gage wear. Store the gage in its protective case when not in use to preserve the ground surfaces. Handle with care to avoid dropping, which can alter the gage diameter and invalidate measurements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.277 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 Class\u003c\/strong\u003e: Class ZZ Minus\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: 19-277-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51694535934258,"sku":"19-277-3","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/245eb560319846308287b92bf7bc8a83.jpg?v=1788325194","url":"https:\/\/voomisupply.com\/products\/spi-19-277-3-class-zz-minus-plug-pin-gage-0-277-in","provider":"Voomi Supply","version":"1.0","type":"link"}
