Class ZZ is the standard tolerance class for general-purpose inspection, and the minus designation means the gage is manufactured to the lower end of the tolerance range, providing a conservative check for minimum hole size. With a tolerance of 0.0002 inches, this gage delivers repeatable, accurate measurement results in tool rooms, production floors, and quality inspection stations. It is constructed from steel for durability and dimensional stability under normal shop conditions.\u003c\/p\u003e\n\u003cp\u003eThis plug pin gage is used in metalworking, machining, and precision manufacturing environments where hole diameter verification is required. It suits inspection tasks on drilled, reamed, or bored holes in metal parts and assemblies. Typical users include machinists, quality control technicians, and toolroom personnel who need a reliable, low-cost method to confirm that a hole meets minimum dimensional requirements before parts move to the next stage of production or assembly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ tolerance class — suitable for general-purpose production and inspection gauging\u003c\/li\u003e\n  \u003cli\u003eMinus designation provides conservative minimum-hole verification\u003c\/li\u003e\n  \u003cli\u003e0.0002-inch tolerance for precise dimensional confirmation\u003c\/li\u003e\n  \u003cli\u003eSteel construction offers durability and resistance to wear in shop environments\u003c\/li\u003e\n  \u003cli\u003eCompact single-pin format for straightforward go\/no-go hole checking\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose Class ZZ minus plug pin gage suitable for go\/no-go inspection of holes with a 0.124-inch nominal diameter in standard machining and quality control applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug pin gages are handled and used by machinists and quality inspection personnel — no special trade license is required, but proper gauging technique is essential for accurate results. Clean the gage and the hole to be measured before use to prevent debris from affecting readings. Never force a plug gage into a hole; apply light, consistent hand pressure only. Store the gage in a protective case away from moisture and temperature extremes to preserve its calibrated dimensions.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.124 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 Designation\u003c\/strong\u003e: Minus\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: 19-124-7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51693429784882,"sku":"19-124-7","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/775358a0cfe37e0a158aeb43e97e4b7c.jpg?v=1788312268","url":"https:\/\/voomisupply.com\/products\/spi-19-124-7-class-zz-minus-plug-pin-gage-0-124-in","provider":"Voomi Supply","version":"1.0","type":"link"}
