It measures bore diameters at 0.191 inches with a tolerance of 0.0002 inches, making it suitable for applications where tight dimensional control is required. The gage is constructed from steel for durability and consistent performance under repeated use. Machinists, quality control technicians, and tool room professionals use plug gages like this one to verify that drilled, reamed, or bored holes meet specified dimensional requirements before parts move to the next stage of production.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is intended for use in precision inspection tasks on the shop floor or in a dedicated metrology area. Class ZZ Plus gages are typically used for production go\/no-go inspection of hole diameters in machined components. The 0.191-inch size is commonly encountered in light manufacturing, fixture building, and general machining operations where small-diameter hole verification is part of the quality process.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.191-inch nominal diameter for precise small-bore measurement\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus tolerance rating at 0.0002 inches for reliable go\/no-go inspection\u003c\/li\u003e\n  \u003cli\u003eSteel construction for wear resistance and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.2 pounds for easy handling during inspection\u003c\/li\u003e\n  \u003cli\u003eSingle-piece package quantity for individual tooling procurement\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 hole inspection applications requiring a 0.191-inch nominal diameter measurement.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are typically handled and used by quality technicians or machinists following standard metrology practices. Before use, clean the gage and the bore being checked to remove chips, coolant, or debris that could affect accuracy. Do not force the gage into a hole; excessive force can damage both the gage and the workpiece. Store the gage in a protective case away from other tools to prevent surface damage and maintain calibration integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter of Measurement\u003c\/strong\u003e: 0.191 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  \u003cli\u003e\n\u003cstrong\u003eGage Class\u003c\/strong\u003e: ZZ Plus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 29-191-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51694637613362,"sku":"29-191-4","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0f479f8812277b22df785280fd8f817f.jpg?v=1788326589","url":"https:\/\/voomisupply.com\/products\/spi-29-191-4-class-zz-plus-plug-gage-0-191-in","provider":"Voomi Supply","version":"1.0","type":"link"}
