It measures a nominal diameter of 0.154 inches with a tolerance of 0.0002 inches, making it suitable for verifying close-tolerance drilled, reamed, or bored holes. Constructed from steel, this gage provides the wear resistance and dimensional stability required for repeated use in production and inspection environments. Machinists, tool and die makers, and quality technicians use Class ZZ Plus plug gages as a reliable go\/no-go or dimensional reference standard.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is used in shop floor and inspection room settings where hole diameter verification is required. Typical applications include checking finished bores in machined components, verifying drill and reamer output, and confirming fit before assembly. The 0.154-inch diameter makes it appropriate for small-bore inspection tasks common in precision machining, toolmaking, and manufacturing quality assurance workflows.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal measurement diameter of 0.154 inches for small-bore inspection\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus tolerance rating of 0.0002 inches for precise dimensional verification\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and dimensional stability under repeated use\u003c\/li\u003e\n  \u003cli\u003eCompact, single-piece gage suitable for bench and floor inspection use\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 1 for individual replacement or toolbox stocking\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard plug gage for use in any inspection setup requiring a 0.154-inch diameter Class ZZ Plus go\/no-go or dimensional reference standard.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by machinists and quality control technicians and do not require power or mechanical installation. Store the gage in a protective case or holder when not in use to prevent damage to the precision-ground surface. Clean the gage and the bore being measured before use to avoid measurement error caused by debris or oil film. Do not force the gage into an undersized hole, as this can damage the gage land and compromise accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter of Measurement\u003c\/strong\u003e: 0.154 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: 29-154-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51710856757554,"sku":"29-154-2","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2c9c0a516b7fe70c652ea83ea45ac231.jpg?v=1788471474","url":"https:\/\/voomisupply.com\/products\/spi-29-154-2-class-zz-plus-plug-gage-0-154-in","provider":"Voomi Supply","version":"1.0","type":"link"}
