Built from steel, this pin gage measures 0.04 inches in diameter and carries a tolerance of 0.0002 inches, making it suitable for go\/no-go inspection routines and dimensional verification work. Class ZZ is a widely recognized tolerance grade for general-purpose inspection gages. Machinists, quality control technicians, and tool room personnel use plug pin gages like this one to verify that drilled, reamed, or punched holes fall within specified dimensional limits.\u003c\/p\u003e\n\u003cp\u003eThis pin gage is used in shop floor and inspection room environments where consistent, reliable hole-size verification is required. It fits standard gage handle sets and is appropriate for use in light manufacturing, precision machining, and quality assurance workflows. The minus designation indicates the gage is manufactured to the lower end of the nominal diameter tolerance, which is standard practice for plug gages used in go-gage applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ tolerance grade for general-purpose dimensional inspection\u003c\/li\u003e\n  \u003cli\u003eMinus designation for go-gage application at lower tolerance boundary\u003c\/li\u003e\n  \u003cli\u003e0.0002 inch tolerance for reliable hole-size verification\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in shop and inspection environments\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard plug gage handles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use plug pin gage fitting standard gage handle sets appropriate for 0.04 inch nominal diameter inspection applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug pin gages are handled by quality control technicians and machinists during part inspection. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the steel surface. Do not force the pin gage into a hole, as this can damage both the gage and the workpiece. Store pin gages in a protective case away from abrasive materials to maintain calibration integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 0.04 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: 19-040-5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51690466083122,"sku":"19-040-5","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/279b46a91a167f906d6c21559bc1c528.jpg?v=1788270385","url":"https:\/\/voomisupply.com\/products\/spi-19-040-5-class-zz-minus-plug-pin-gage-0-04-in-dia","provider":"Voomi Supply","version":"1.0","type":"link"}
