It measures 0.185 inches in diameter and holds a minus tolerance of 0.0002 inches, placing it within the Class ZZ specification for general-purpose inspection work. This gage is used by machinists, quality control technicians, and toolroom personnel to verify hole size conformance during production or incoming inspection. The steel construction provides durability under repeated use in shop environments.\u003c\/p\u003e\n\u003cp\u003eClass ZZ plug gages are the standard choice for inspection of holes in manufactured parts where a high-precision master gage is not required. The 19-185-8 is suited for checking drilled or reamed through-holes and blind holes in metalworking, fabrication, and light manufacturing settings. It is a single-end gage intended for manual hand use without requiring fixtures or special tooling. This size covers applications where a nominal 0.185-inch hole diameter must be verified against a defined tolerance band.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ minus tolerance designation for general-purpose hole inspection\u003c\/li\u003e\n  \u003cli\u003e0.185 inch nominal diameter for precise go\/no-go gauging\u003c\/li\u003e\n  \u003cli\u003eMinus tolerance of 0.0002 inches machined to ANSI Class ZZ standards\u003c\/li\u003e\n  \u003cli\u003eSteel construction for resistance to wear in production environments\u003c\/li\u003e\n  \u003cli\u003eSingle-piece design requires no assembly before use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-use Class ZZ minus plug pin gage for manual inspection of 0.185-inch nominal diameter holes in metalworking and manufacturing applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug pin gages are inspected and used by quality control technicians and machinists without power tools or utilities. Handle the gage carefully to avoid dropping, which can alter the calibrated diameter. Clean the gage and the hole being measured before use to prevent debris from affecting readings. Store in a protective case away from other tools to prevent surface damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Class\u003c\/strong\u003e: ZZ Minus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.185 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance (Decimal Inch)\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\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: 19-185-8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51720403419442,"sku":"19-185-8","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/36a1b7144d3aee17c2ee1d5785750ef7.jpg?v=1788563501","url":"https:\/\/voomisupply.com\/products\/spi-19-185-8-class-zz-minus-plug-pin-gage-0-185-in","provider":"Voomi Supply","version":"1.0","type":"link"}
