Plug gages of this class are used for go\/no-go dimensional inspection in precision machining, manufacturing, and quality control environments. The tight tolerance makes this gage suitable for checking bores and drilled holes where close-fit assembly is required. Machinists, quality technicians, and tool-and-die professionals rely on Class ZZ Plus gages for fast, repeatable pass\/fail verification without the need for electronic measuring equipment.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is intended for precision inspection work in machine shops, fabrication facilities, and production environments where small-diameter hole verification is part of the quality control process. It is well suited for checking pilot holes, dowel pin bores, and similar features in ferrous and non-ferrous workpieces. The compact size and light weight make it practical for bench inspection as well as in-process checks on the shop floor.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal measurement diameter of 0.075 inches for small-bore inspection\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus tolerance of 0.0002 inches for reliable pass\/fail gauging\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and wear resistance in production use\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.2 pounds, suited for handheld use\u003c\/li\u003e\n  \u003cli\u003eSingle-piece unit ready for immediate use without additional setup\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 precision inspection applications requiring a 0.075-inch nominal bore diameter check in Class ZZ Plus tolerance grade.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by machinists and quality control technicians following standard metrology practices. Keep the gage clean and lightly oiled when not in use to prevent corrosion and maintain accuracy. Do not force the gage into an undersized bore, as this can damage the gage surface and compromise measurement integrity. Store in a protective case away from heat sources and abrasive materials to preserve tolerance accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Class\u003c\/strong\u003e: ZZ Plus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 0.075 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches\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: 29-075-9\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51691388469554,"sku":"29-075-9","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c03b3bb06c1329d79cc552e288a3e22f.jpg?v=1788284345","url":"https:\/\/voomisupply.com\/products\/spi-29-075-9-class-zz-plus-plug-gage-0-075-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
