With a nominal diameter of 0.627 inches and a tolerance of 0.0002 inches (minus), this gage provides a reliable go\/no-go reference for confirming that a hole falls within acceptable dimensional limits. The minus designation means the gage is manufactured undersize relative to nominal, consistent with Class ZZ standards for inspection-grade tooling. At 0.2 pounds, it is a compact, hand-held tool suited to bench inspection environments and light production use.\u003c\/p\u003e\n\u003cp\u003eThis plug pin gage is used in manufacturing, machining, and metrology applications where hole diameter verification is required. It is appropriate for inspecting drilled, reamed, or bored holes in metal, plastic, or composite workpieces. Machinists, quality control inspectors, and tool room technicians use Class ZZ plug gages for incoming inspection, in-process checking, and final part verification across light industrial and job shop settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal diameter of 0.627 inches for direct hole size verification\u003c\/li\u003e\n  \u003cli\u003eClass ZZ minus tolerance of 0.0002 inches, machined undersize relative to nominal\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eCompact form factor at 0.2 pounds for easy single-hand use at the inspection bench\u003c\/li\u003e\n  \u003cli\u003eSingle-piece package quantity suitable for individual tooling procurement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Class ZZ minus plug pin gage for use with conventional gage handle sets and collet-style holders sized for the 0.627 inch diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug pin gages should be handled with clean, dry hands or lint-free gloves to prevent corrosion from skin oils. Store the gage in a protective case or padded tray when not in use to avoid nicks or surface damage that could affect dimensional accuracy. Calibration against a certified reference standard is recommended before first use and at regular intervals per your quality management procedures. No power tools or cutting equipment are involved in standard gage use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.627 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches (minus)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Class\u003c\/strong\u003e: Class ZZ\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: 19-627-9\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51693870088498,"sku":"19-627-9","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b265a233867b0e7f360dedef5744c491.jpg?v=1788318331","url":"https:\/\/voomisupply.com\/products\/spi-19-627-9-class-zz-minus-plug-pin-gage-0-627-in","provider":"Voomi Supply","version":"1.0","type":"link"}
