It measures a nominal diameter of 0.074 inches with a tolerance of 0.0002 inches, making it suitable for applications where tight go\/no-go verification is required. Constructed from steel for durability and dimensional stability, this plug gage is a standard tool in quality control environments. Machinists, tool-and-die makers, and inspection technicians use this type of gage to verify hole diameter conformance to drawing tolerances on the shop floor or in the inspection room.\u003c\/p\u003e\n\u003cp\u003eClass ZZ Plus plug gages are typically used in production and inspection settings where moderate-precision hole verification is needed. This gage is appropriate for checking drilled, reamed, or broached holes in metal, plastic, or composite workpieces. It is suited for both incoming inspection and in-process quality checks. The small 0.074-inch diameter makes it particularly relevant for tight-tolerance work in aerospace, automotive, and general machining applications where small-bore accuracy is critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus tolerance rating for reliable go\/no-go dimensional verification\u003c\/li\u003e\n  \u003cli\u003eNominal measurement diameter of 0.074 inches\u003c\/li\u003e\n  \u003cli\u003eTolerance of 0.0002 inches for precise hole conformance checking\u003c\/li\u003e\n  \u003cli\u003eSteel construction for wear resistance and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eCompact, single-piece form factor suited for small-bore inspection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Class ZZ Plus plug gage for use in go\/no-go inspection of holes and bores nominally sized at 0.074 inches in diameter across a range of machined workpiece materials and industries.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages should be handled and stored carefully to prevent damage to the precision-ground surfaces. Clean the gage and the hole being inspected before use to avoid debris-induced measurement error. Do not force the gage into an undersized hole, as this can damage the gage surface and produce inaccurate results. Periodic calibration 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\u003eMeasurement Diameter\u003c\/strong\u003e: 0.074 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Class\u003c\/strong\u003e: ZZ Plus\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: 29-074-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51707959574834,"sku":"29-074-2","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/438a71359070fea2f1225288e8320794.jpg?v=1788443120","url":"https:\/\/voomisupply.com\/products\/spi-29-074-2-class-zz-plus-plug-gage-0-074-in","provider":"Voomi Supply","version":"1.0","type":"link"}
