Manufactured from steel, it is used to verify that a hole or bore meets minimum acceptable size requirements. Class ZZ is the standard tolerance class for go\/no-go inspection of production parts where high-precision master-grade gages are not required. Machinists, quality control inspectors, and tool room technicians use plug pin gages as part of routine dimensional verification on machined components.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for use in machine shops, production environments, and inspection departments working with bores nominally sized at 0.534 inches. A minus-tolerance gage checks the low limit of a hole, confirming the bore has not been cut undersize. It is appropriate for applications involving drilled, reamed, or bored holes in metal, plastic, or composite workpieces where dimensional conformance is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ tolerance class for general-purpose production inspection\u003c\/li\u003e\n  \u003cli\u003eMinus designation checks the low-limit condition of the bore\u003c\/li\u003e\n  \u003cli\u003e0.534 inches nominal diameter with 0.0002 inches tolerance\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and wear resistance in shop environments\u003c\/li\u003e\n  \u003cli\u003eSingle-piece design for straightforward go\/no-go inspection workflow\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use gage for go\/no-go inspection setups requiring a Class ZZ minus plug gage at the 0.534 inches nominal diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug pin gages are handled and used by quality control inspectors or machinists and require no installation in the traditional sense. Store gages in a protective case and keep them clean and lightly oiled to prevent corrosion. Do not force the gage into a bore; apply only light hand pressure to avoid wear or damage to the gage surface. Periodic recalibration against NIST-traceable standards is recommended to maintain measurement integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.534 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\u003eTolerance (Decimal Inch)\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\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: 19-534-7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51717387780402,"sku":"19-534-7","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cdcdd757d58156edb0a0ef85943e1750.jpg?v=1788539591","url":"https:\/\/voomisupply.com\/products\/spi-19-534-7-class-zz-minus-plug-pin-gage-0-534-in","provider":"Voomi Supply","version":"1.0","type":"link"}
