Manufactured from steel, this go\/no-go style inspection tool holds a tolerance of 0.0002 inches, making it suitable for general-purpose quality control in machine shops, production environments, and maintenance settings. Metrology technicians and machinists use plug gages like the 29-670-7 to confirm hole size acceptance without the need for calipers or micrometers at the inspection point. The Class ZZ Plus rating indicates a commercial-grade tolerance class appropriate for inspection of standard-tolerance workpieces.\u003c\/p\u003e\n\u003cp\u003eThe 29-670-7 is used in manufacturing, toolroom, and maintenance-repair-operations environments wherever precise hole acceptance testing is required. It is appropriate for checking holes in metal, plastic, or composite workpieces machined to standard tolerances. The gage is typically employed as a final inspection step after drilling, boring, or reaming operations where hole diameter conformance must be confirmed before assembly or further processing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.67 inch nominal diameter for direct hole inspection without calculation\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus tolerance rating at 0.0002 inches for commercial-grade inspection\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and wear resistance in production use\u003c\/li\u003e\n  \u003cli\u003eCompact, lightweight form at 0.2 pounds for easy handling at the workstation\u003c\/li\u003e\n  \u003cli\u003eSingle-piece unit ships individually for direct deployment to inspection stations\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 gage for inspection of holes with a nominal diameter of 0.67 inches in standard commercial-tolerance applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled by quality control technicians and machinists and require no permanent installation. Before use, clean the gage and the hole being inspected to remove chips, coolant, or debris that could cause false readings or gage wear. Do not force the gage through an undersized hole, as this will damage the gage surface and compromise measurement accuracy. Store the gage in a protected case away from other metal tools to prevent nicks and corrosion.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter of Measurement\u003c\/strong\u003e: 0.67 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\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: 29-670-7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51709105176882,"sku":"29-670-7","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f5e7b987adc0e220cfdc8df559c7743a.jpg?v=1788451374","url":"https:\/\/voomisupply.com\/products\/spi-29-670-7-class-zz-plus-plug-gage-0-67-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
