Built to Class ZZ tolerance standards, this go-style gage checks whether a hole is within specification by confirming minimum acceptable size. The gage measures 0.583 inches in diameter with a tolerance of 0.0002 inches, making it suitable for quality control work where dimensional accuracy is critical. Constructed from steel, it is durable enough for repeated use in shop-floor and inspection-room environments. Machinists, quality technicians, and tool-and-die professionals rely on plug pin gages like this one for fast, reliable dimensional verification.\u003c\/p\u003e\n\u003cp\u003eThis gage is designed for use in manufacturing, machining, and metrology environments where hole diameter conformance must be confirmed to tight tolerances. It is appropriate for both production-line inspection and bench-level quality checks. The 0.583-inch diameter and Class ZZ minus designation make it a practical tool for verifying holes drilled, reamed, or bored to that nominal size. It is typically used in conjunction with a matching go\/no-go gage set or as a standalone minus plug for confirming minimum hole size acceptance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ tolerance grade for standard inspection and quality control applications\u003c\/li\u003e\n  \u003cli\u003eMinus plug configuration checks minimum acceptable hole diameter\u003c\/li\u003e\n  \u003cli\u003e0.583-inch nominal diameter with 0.0002-inch tolerance\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and dimensional stability under 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 an OEM-style plug pin gage for use in standard bore and hole inspection applications requiring a 0.583-inch nominal diameter at Class ZZ minus tolerance.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug pin gages are handled and used by machinists and quality control technicians — no installation in the traditional sense is required. Before use, ensure the gage and workpiece surfaces are clean and free of burrs, chips, or debris that could affect measurement accuracy. Do not force the gage into an undersized hole, as this can damage both the gage and the workpiece. Store the gage in a protective case or sleeve and calibrate periodically according to your facility's metrology standards.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 0.583 inches\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\u003eGage Class\u003c\/strong\u003e: 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: 19-583-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51699753517362,"sku":"19-583-4","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/da6646b92ea876af6087ff3b75a3a9f6.jpg?v=1788380327","url":"https:\/\/voomisupply.com\/products\/spi-19-583-4-class-zz-minus-plug-pin-gage-0-583-in","provider":"Voomi Supply","version":"1.0","type":"link"}
