This go\/no-go style gage is used to verify hole diameters and bore sizes to a tolerance of 0.0002 inches, making it well-suited for inspection and quality control work in precision machining and manufacturing environments. Licensed machinists, toolroom technicians, and quality inspectors rely on pin gages like this one to confirm that drilled, reamed, or bored features fall within acceptable tolerance bands before a part proceeds to the next stage of production.\u003c\/p\u003e\u003cp\u003eThis gage is appropriate for use in job shops, toolrooms, and production inspection stations where hole location and diameter conformance must be verified against tight tolerances. The minus designation indicates the gage is ground to the low side of the nominal diameter, as defined by Class ZZ specifications. It is a common choice for general-purpose inspection in both low-volume prototype work and higher-volume production runs where process control documentation is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eClass ZZ minus tolerance classification for general-purpose hole inspection\u003c\/li\u003e\n\u003cli\u003eNominal diameter of 0.656 inches with a 0.0002-inch tolerance\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability and dimensional stability in shop environments\u003c\/li\u003e\n\u003cli\u003eCompact single-gage format, sold individually for targeted inspection needs\u003c\/li\u003e\n\u003cli\u003eMinus ground designation allows use as a go gage to confirm minimum acceptable bore size\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Class ZZ minus plug pin gage for general-purpose dimensional inspection of 0.656-inch nominal diameter holes and bores across a wide range of machined components.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePin gages are handled and used by machinists, metrologists, and quality technicians — no installation in the traditional sense applies. Store the gage in its protective sleeve or case when not in use to prevent surface damage that could affect accuracy. Clean the gage and the bore being checked before use to remove chips, coolant, or debris that could produce false readings. Never force a pin gage into a bore; excessive force can damage both the gage and the workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.656 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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 19-656-8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51693427556658,"sku":"19-656-8","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/63ab05a75ae979dd7979db322a155edc.jpg?v=1788312223","url":"https:\/\/voomisupply.com\/products\/spi-19-656-8-class-zz-minus-plug-pin-gage-0-656-in","provider":"Voomi Supply","version":"1.0","type":"link"}
