It is used to verify whether a hole or bore meets its minimum acceptable size by confirming the feature accepts the gage without interference. Class ZZ designates the tolerance grade applied to the gage itself, with a tolerance of 0.0002 inches on the gage member. The minus designation means the gage is manufactured to the lower end of the tolerance range, making it suitable for go-gage applications in production and inspection environments. Machinists, quality control technicians, and toolroom personnel are the primary users of this type of gage.\u003c\/p\u003e\n\u003cp\u003eThis plug pin gage is used in dimensional inspection of drilled, reamed, or bored holes in metal, plastic, and composite workpieces. It is suited for incoming inspection, in-process quality control, and final part verification in manufacturing and job shop environments. The 0.726 inch diameter corresponds to a specific nominal hole size and is used wherever that bore dimension must be confirmed to tolerance. Individual pin gages like this one are also used as replacements in handle-style pin gage sets when a specific size is worn or lost.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ tolerance grade with 0.0002 inch gage tolerance for production-level inspection\u003c\/li\u003e\n  \u003cli\u003eMinus designation confirms go-gage function at the lower tolerance boundary\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides durability for repeated use in shop floor conditions\u003c\/li\u003e\n  \u003cli\u003e0.726 inch nominal diameter for precise bore verification at that hole size\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.2 pounds, suitable for bench and handheld inspection use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement or individual pin gage for use in standard handle-style pin gage holders accepting the 0.726 inch diameter range.

Clean the gage and the part bore before use to remove chips, coolant, or debris that could cause false readings or gage wear. Do not force the gage into a hole; if resistance is encountered, the bore is undersized or the hole is not clean. Periodic calibration against a certified master is recommended to confirm the gage remains within its stated tolerance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.726 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: 19-726-9\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51723467817266,"sku":"19-726-9","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d02049f77e1bfa31128803f5b58c1b98.jpg?v=1788605257","url":"https:\/\/voomisupply.com\/products\/spi-19-726-9-class-zz-minus-plug-pin-gage-0-726-in","provider":"Voomi Supply","version":"1.0","type":"link"}
