It holds a tolerance of 0.0002 inches, making it a reliable go\/no-go inspection tool for production and quality control environments. Constructed from steel, this gage is designed for repeated use on the shop floor without loss of dimensional accuracy. Machinists, quality technicians, and precision manufacturing professionals use this type of gage to confirm that finished bores fall within acceptable tolerance limits before parts move to the next stage of production.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is suited for use in precision machining shops, tool rooms, and manufacturing facilities where bore diameter verification is part of standard inspection protocol. It applies to any application requiring confirmation of a 0.975-inch nominal bore, including hydraulic components, mechanical assemblies, and general metalworking. The compact size and steel construction make it practical for both bench inspection and in-process checks at the machine.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal measurement diameter of 0.975 inches for precise bore verification\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus tolerance rating of 0.0002 inches for go\/no-go inspection use\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and dimensional stability under repeated use\u003c\/li\u003e\n  \u003cli\u003eSingle-piece package quantity suited for individual technician or toolroom use\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.2 pounds for easy handling during inspection tasks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use inspection gage for any application requiring a 0.975-inch Class ZZ Plus plug gage in standard steel construction.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by quality technicians and machinists as inspection instruments, not installed components. Clean the gage and bore surfaces before use to prevent false readings from chips or coolant residue. Store the gage in its protective case when not in use to prevent wear or corrosion that could compromise tolerance accuracy. Do not force the gage into a bore; resistance indicates the bore is undersize and requires further machining.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.975 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  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111600\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: 29-975-0\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51718744113458,"sku":"29-975-0","price":16.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/851a1afd6f7345bd93765e22cbf3798f.jpg?v=1788555318","url":"https:\/\/voomisupply.com\/products\/spi-29-975-0-class-zz-plus-plug-gage-0-975-in","provider":"Voomi Supply","version":"1.0","type":"link"}
