Built from steel, this pin gage measures 0.8440 inches in diameter with a tolerance of 0.0002 inches and an overall length of 2 inches. It ships with a Certificate of Accuracy backed by NIST traceability, confirming the gage meets the dimensional requirements for Class ZZ minus classification. Machinists, quality control technicians, and tool-and-die professionals use this type of gage as part of go\/no-go inspection routines in production and inspection environments.\u003c\/p\u003e\n\u003cp\u003eThis plug pin gage is suited for NoGo inspection applications where confirming a hole is within maximum material condition is required. It is also appropriate for setting micrometers, verniers, and other measuring devices that need a traceable reference standard at the 0.8440-inch diameter. Typical use environments include machine shops, inspection labs, and manufacturing floors where tight-tolerance hole inspection is part of standard quality workflow.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ minus classification for NoGo inspection of holes at 0.8440 inches diameter\u003c\/li\u003e\n  \u003cli\u003eTolerance of 0.0002 inches ensures consistent, reliable measurement\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides durability in shop and lab environments\u003c\/li\u003e\n  \u003cli\u003e10 micro surface finish coating supports accurate contact measurement\u003c\/li\u003e\n  \u003cli\u003eIncludes Certificate of Accuracy with NIST traceability\u003c\/li\u003e\n  \u003cli\u003eCompact 2-inch overall length for easy handling in tight inspection setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style plug pin gage for use in go\/no-go inspection setups, and compatible for setting micrometers, verniers, and other measuring devices requiring a traceable 0.8440-inch diameter reference.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis gage is handled and used by machinists and quality technicians, not installed in the traditional sense. Store the pin in its protective case when not in use to prevent surface damage that could affect measurement accuracy. Clean the pin and the bore being inspected before use to avoid false readings caused by debris or coolant residue. Never force a plug gage into a hole, as this can damage the gage surface and invalidate its traceability certification.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter of Measurement\u003c\/strong\u003e: 0.8440 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 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\u003eCoating\/Finish\u003c\/strong\u003e: 10 Micro\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass\u003c\/strong\u003e: ZZ Minus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: NoGo Inspection, Setting Micrometers, Verniers, and Other Measuring Devices\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Certificate of Accuracy with NIST Traceability\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: VERMONT GAGE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 111284400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51735446454578,"sku":"111284400","price":22.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1cf04934d75d3eb37d973f6ea4b25c4d_e326cf54-7216-4dd4-bf18-d7d725008760.jpg?v=1788772492","url":"https:\/\/voomisupply.com\/products\/vermont-gage-111284400-class-zz-minus-plug-pin-gage-0-8440-in","provider":"Voomi Supply","version":"1.0","type":"link"}
