It measures 0.02 inches in diameter and holds a tolerance of 0.0002 inches, making it suitable for go\/no-go inspection workflows where tight dimensional control is required. Machined from steel, this gage provides the rigidity and wear resistance needed for repeated use in production or maintenance environments. Machinists, tool-and-die workers, and quality control technicians are the primary users.\u003c\/p\u003e\n\u003cp\u003eClass ZZ plug gages are designed for general-purpose inspection use rather than master or reference applications. The minus designation means the gage is manufactured to the lower end of the tolerance band, which is standard practice for go-side plug gages used in checking minimum acceptable hole sizes. This gage is appropriate for use in machine shops, maintenance facilities, and light manufacturing settings where small-bore hole verification is part of the inspection process.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.02-inch nominal diameter for small-bore hole inspection\u003c\/li\u003e\n  \u003cli\u003eClass ZZ tolerance class suitable for general-purpose go\/no-go gauging\u003c\/li\u003e\n  \u003cli\u003eMinus tolerance designation for go-side dimensional checking\u003c\/li\u003e\n  \u003cli\u003e0.0002-inch tolerance for consistent, repeatable measurement results\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and resistance to wear during repeated use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose Class ZZ minus plug pin gage for inspecting holes with a nominal diameter of 0.02 inches in standard machining and quality control applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug pin gages are used by machinists and quality technicians during inspection, not installation. Handle the gage with clean, dry hands or cotton gloves to prevent corrosion from skin oils. Store in a protective case or rack away from other tooling to avoid surface damage. Calibrate or verify against a certified master gage at regular intervals to maintain measurement traceability per applicable quality standards.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.02 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: 19-020-7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51710782636338,"sku":"19-020-7","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f6e0f0d98b873f7ec6921e1d01cd6f9c.jpg?v=1788470509","url":"https:\/\/voomisupply.com\/products\/spi-19-020-7-class-zz-minus-plug-pin-gage-0-02-in","provider":"Voomi Supply","version":"1.0","type":"link"}
