Plug pin gages are precision measurement tools used to verify whether a hole or bore meets its dimensional specification. The Class ZZ designation indicates a working-grade gage intended for production floor use, where parts are being checked repeatedly during manufacturing or quality inspection cycles. Constructed from steel, the 19-435-7 delivers the hardness and dimensional stability required for consistent, reliable go\/no-go or dimensional verification tasks. Machinists, quality technicians, and tool-and-die professionals are the primary users of this type of gage.\u003c\/p\u003e\n\u003cp\u003eThis plug pin gage is suited for use in machine shops, manufacturing facilities, and production environments where hole diameter verification is part of standard quality control workflow. It is used to check bored, drilled, or reamed holes in metal, plastic, or composite workpieces. The minus tolerance grind means the gage is manufactured slightly below nominal, following standard gage-making practice for go-type inspection members. At 0.435 inches nominal diameter, this gage fits a common range of precision-drilled and reamed hole sizes found in general machining and light industrial applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.435-inch nominal diameter for precise hole verification at that bore size\u003c\/li\u003e\n  \u003cli\u003eClass ZZ working-grade tolerance for production floor inspection use\u003c\/li\u003e\n  \u003cli\u003eMinus tolerance grind of 0.0002 inches following standard gage-making convention\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides hardness and wear resistance for repeated use\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.2 pounds for easy single-hand operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a working-grade Class ZZ plug pin gage for use in standard production inspection applications requiring verification of 0.435-inch nominal diameter bores.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug pin gages are handled by quality technicians and machinists and require no permanent installation. Store the gage in its case or in a protected rack away from other tooling to prevent nicks or scoring on the gage surface. Clean the gage and the bore being checked before use to avoid false readings caused by chips, coolant, or debris. Handle with care to avoid dropping, as impact can alter the precision ground surface and render the gage out of tolerance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.435 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches (minus)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance (mm)\u003c\/strong\u003e: 0.0002 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Class\u003c\/strong\u003e: Class ZZ\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: 19-435-7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51722900603186,"sku":"19-435-7","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1d9b657226da9e1e86ffca1898fda2f4.jpg?v=1788597609","url":"https:\/\/voomisupply.com\/products\/spi-19-435-7-class-zz-minus-plug-pin-gage-0-435-in","provider":"Voomi Supply","version":"1.0","type":"link"}
