Manufactured from steel, this pin gage checks whether a feature falls within a specified tolerance range. The 19-944-8 has a nominal diameter of 0.944 inches and carries a tolerance of 0.0002 inches, making it suitable for go\/no-go inspection work on machined components. Class ZZ designates the loosest tolerance class in the inch plug gage series, typically applied to inspection of parts produced to commercial-grade tolerances. Machinists, tool-and-die makers, and quality control technicians use this type of gage as part of standard dimensional inspection routines.\u003c\/p\u003e\n\u003cp\u003eThis plug pin gage is used in machine shops, manufacturing facilities, and quality inspection departments where accurate bore verification is required. It is appropriate for checking drilled, reamed, or bored holes in metal and other rigid materials. The 0.944-inch diameter targets mid-range bore sizes common in general-purpose machined parts. Single-piece packaging makes it straightforward to add to an existing gage set or replace a worn member in a current set.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal diameter of 0.944 inches for precise bore inspection\u003c\/li\u003e\n  \u003cli\u003eClass ZZ minus tolerance of 0.0002 inches per inch gage standards\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eMinus designation indicates the gage is ground to the lower boundary of the tolerance band\u003c\/li\u003e\n  \u003cli\u003ePackaged individually for single-member replacement or standalone use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or supplemental member for Class ZZ inch plug gage sets requiring a 0.944-inch diameter pin.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug pin gages are handled and stored by metrology and quality control professionals following standard gage-handling procedures. Clean the gage and the bore being checked before use to prevent debris from affecting readings. Store the pin in a protective case away from humidity and temperature extremes to maintain dimensional stability. Do not force the gage into a hole; controlled hand pressure is standard practice to avoid damage to the gage or the workpiece.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.944 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage 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  \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: 19-944-8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51709472014642,"sku":"19-944-8","price":16.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/35b28dcf6234a6609aa55e06a7c6b8bd.jpg?v=1788456901","url":"https:\/\/voomisupply.com\/products\/spi-19-944-8-class-zz-minus-plug-pin-gage-0-944-in","provider":"Voomi Supply","version":"1.0","type":"link"}
