At 0.943 inches in nominal diameter, this go\/no-go style gage checks whether a feature is within spec by confirming the lower boundary of an acceptable tolerance range. The minus designation means the gage is manufactured to the low side of the nominal dimension, making it appropriate for checking maximum material condition on internal features. Machinists, quality technicians, and tool-and-die professionals use plug gages like this one during in-process and final inspection routines.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for use in machine shops, manufacturing facilities, and quality control environments where precise hole diameter verification is required. It is typically used with a gage handle (sold separately) sized for the 0.943-inch diameter range. Class ZZ is the most widely used tolerance class for plug gages in general-purpose inspection work, offering a practical balance between accuracy and cost for production environments. The 0.943-inch diameter makes this gage appropriate for inspecting bored, drilled, or reamed holes in metal, plastic, or composite workpieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ tolerance class for general-purpose hole inspection\u003c\/li\u003e\n  \u003cli\u003eMinus designation checks the low side of the nominal diameter\u003c\/li\u003e\n  \u003cli\u003e0.000200 inch tolerance for reliable dimensional verification\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in shop environments\u003c\/li\u003e\n  \u003cli\u003e0.943 inch nominal diameter for precise bore gauging\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.2 pounds for easy single-hand use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard plug gage handles sized for the 0.943-inch diameter range.

Insert the gage into the gage handle appropriate for this diameter range before use. Do not force the gage into a bore; apply light, even hand pressure only to avoid scoring the gage or the workpiece. Store in a protective case away from moisture and temperature extremes to preserve dimensional accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.943 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Class\u003c\/strong\u003e: Class ZZ\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.000200 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDesignation\u003c\/strong\u003e: 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: 19-943-0\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51721059762482,"sku":"19-943-0","price":16.52,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c8579d1159775edc2ce54aa508b476c2.jpg?v=1788572967","url":"https:\/\/voomisupply.com\/products\/spi-19-943-0-class-zz-minus-plug-pin-gage-0-943-in","provider":"Voomi Supply","version":"1.0","type":"link"}
