It measures a nominal diameter of 0.998 inches with a tolerance of 0.0002 inches, providing the tight accuracy required for go\/no-go dimensional verification. Built from steel for durability and wear resistance, this plug gage is a standard tool for quality control technicians and machinists who need reliable, repeatable measurement results on production or inspection floors.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for use in machine shops, tool rooms, and manufacturing facilities where hole diameter verification is part of a quality assurance process. It fits into workflows that require compliance with dimensional tolerances on bored, drilled, or reamed holes. The compact form factor and 0.2-pound weight make it easy to handle during repeated inspection cycles.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus tolerance rating for precision dimensional inspection\u003c\/li\u003e\n  \u003cli\u003e0.998-inch nominal measurement diameter\u003c\/li\u003e\n  \u003cli\u003e0.0002-inch tolerance for tight accuracy requirements\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and wear resistance\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.2 pounds for easy single-hand use during inspection\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 holes and bores at a nominal diameter of 0.998 inches.

Clean the gage and the bore being measured before use to ensure accurate readings. Do not force the gage into a hole; apply only light, steady pressure. Calibration and periodic re-inspection against gage blocks or master rings is recommended to maintain measurement accuracy over time.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 0.998 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  \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: 29-998-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51698622791986,"sku":"29-998-2","price":16.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fd690c43e6644655f609526c466c7dd0.jpg?v=1788365595","url":"https:\/\/voomisupply.com\/products\/spi-29-998-2-class-zz-plus-plug-gage-0-998-in-dia","provider":"Voomi Supply","version":"1.0","type":"link"}
