Built from steel, this gage provides a tolerance of 0.0002 inches, conforming to Class ZZ minus specifications for general-purpose inspection work. It is used by machinists, quality control technicians, and tool-and-die professionals to verify that a hole or bore falls within acceptable dimensional limits. The minus designation indicates the gage is ground to the lower tolerance boundary, consistent with standard go-gage practice.\u003c\/p\u003e\n\u003cp\u003eClass ZZ plug gages at this diameter range are well suited for production floor inspection and incoming quality checks on machined components in light manufacturing, tool rooms, and precision fabrication shops. The 0.191-inch size is commonly called out in standard hole charts and fits applications where close-tolerance bore verification is required without the cost of higher-class precision gages.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.191-inch nominal diameter for precise bore verification\u003c\/li\u003e\n  \u003cli\u003eClass ZZ minus tolerance classification for general-purpose go-gage inspection\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and wear resistance in production environments\u003c\/li\u003e\n  \u003cli\u003e0.0002-inch tolerance ensures consistent and repeatable dimensional checks\u003c\/li\u003e\n  \u003cli\u003eCompact, single-piece design suitable for bench-top and floor-level inspection\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 pin gage for general-purpose dimensional inspection applications requiring a Class ZZ minus gage at 0.191-inch diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug pin gages are used by quality control technicians and machinists and require no permanent installation. Before use, clean the gage and the bore being checked to remove chips, coolant, and debris that could affect readings. Handle gages carefully to avoid dropping or striking, as impact damage can alter the ground diameter and invalidate the tolerance class. Store in a protective case or roll when not in use to prevent surface damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\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\u003eTolerance Class\u003c\/strong\u003e: Class ZZ Minus\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: 19-191-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51721890660658,"sku":"19-191-6","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3c62993b180af628b7fb5756b8d19fd4.jpg?v=1788582664","url":"https:\/\/voomisupply.com\/products\/spi-19-191-6-class-zz-minus-plug-pin-gage-0-191-in","provider":"Voomi Supply","version":"1.0","type":"link"}
