It checks whether a drilled, reamed, or bored hole falls within acceptable dimensional limits. The gage measures holes at a nominal diameter of 0.067 inches and holds a tolerance of 0.0002 inches, making it suitable for tight-tolerance work where go\/no-go verification is required. Constructed from steel, it is built to resist wear during repeated use on the shop floor or in an inspection environment. Machinists, quality technicians, and tool-and-die professionals rely on this type of gage as a fast, reliable alternative to measuring instruments when checking production parts.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is used in precision manufacturing and inspection settings where small-diameter hole verification is part of routine process control. It is appropriate for residential shop work, industrial production lines, and quality labs working with small-bore features in metal, plastic, or composite components. The 0.067-inch diameter range targets very small hole geometries common in instrument components, small fastener clearances, and precision-machined assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus tolerance classification for go\/no-go hole inspection\u003c\/li\u003e\n  \u003cli\u003eNominal diameter of 0.067 inches for small-bore measurement\u003c\/li\u003e\n  \u003cli\u003eTolerance of 0.0002 inches for tight-tolerance verification\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and wear resistance\u003c\/li\u003e\n  \u003cli\u003eCompact, lightweight design at 0.2 pounds for easy bench or in-process use\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 small-diameter holes in precision machined parts.

Before use, clean both the gage and the hole being measured to remove chips, coolant, or debris that could affect accuracy. Never force the gage into a hole; insertion should be smooth and consistent with proper gage technique. Store the gage in a protective case away from other tools to prevent surface damage that could compromise measurement accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.067 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches (0.0002 mm)\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: 29-067-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51694336475442,"sku":"29-067-6","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ad3d8e216859bd27a7487733dc5a2f92.jpg?v=1788323297","url":"https:\/\/voomisupply.com\/products\/spi-29-067-6-class-zz-plus-plug-gage-0-067-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
