Plug gages are go\/no-go inspection tools used to confirm that a drilled, reamed, or bored hole falls within an acceptable dimensional range. This gage is constructed from steel for wear resistance and dimensional stability. It is a standard hand tool used by machinists, quality control inspectors, and toolroom technicians during part inspection and process verification on the shop floor or in the inspection lab.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is suited for small-diameter hole inspection in precision machining environments, including manufacturing, fabrication, and toolroom applications. The Class ZZ Plus designation indicates a commercial-grade tolerance class appropriate for general inspection of production parts where close dimensional control is required. Typical use cases include incoming inspection, in-process quality checks, and final part verification on components with 0.179-inch nominal hole features.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal measurement diameter of 0.179 inches for precise small-hole inspection\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus tolerance class rated at 0.0002 inches for reliable go\/no-go inspection\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides durability and dimensional stability under repeated use\u003c\/li\u003e\n  \u003cli\u003eCompact, lightweight design at 0.2 pounds for easy single-hand operation\u003c\/li\u003e\n  \u003cli\u003eStandard single-piece packaging suitable for individual toolroom or bench 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 general-purpose inspection of 0.179-inch nominal diameter holes in machined components across a wide range of manufacturing and toolroom applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are used by machinists and quality inspectors and do not require power or mechanical installation. Before use, clean the gage and the hole being inspected to remove chips, coolant, or debris that could affect the reading. Apply light, even hand pressure when inserting the gage — never force a plug gage, as this can damage the gage or the workpiece. Store the gage in its case or on a clean surface away from abrasive materials to preserve its calibrated tolerance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.179 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\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: 29-179-9\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51689656353074,"sku":"29-179-9","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c2a8ca787159e958fdd8fe367f7c429b.jpg?v=1788262521","url":"https:\/\/voomisupply.com\/products\/spi-29-179-9-class-zz-plus-plug-gage-0-179-in","provider":"Voomi Supply","version":"1.0","type":"link"}
