It is manufactured from steel and holds a tolerance of 0.0002 inches, making it appropriate for go\/no-go dimensional inspection in production and maintenance environments. This tool is used by machinists, quality control technicians, and precision tradespeople who need reliable, repeatable verification of inside dimensions. The minus designation indicates the gage is ground to the lower tolerance limit, consistent with standard Class ZZ minus specifications for plug gages.\u003c\/p\u003e\n\u003cp\u003eThis pin gage is suited for use in manufacturing shops, machine rooms, and field inspection applications where tight dimensional control is required. It is commonly used to check hole size acceptance on machined parts, castings, and drilled components. At 0.3460 inches nominal diameter, it falls within a commonly used range for checking standard fractional and decimal bore sizes in light industrial and mechanical assembly work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal measurement diameter of 0.3460 inches for precise bore verification\u003c\/li\u003e\n  \u003cli\u003eClass ZZ minus tolerance of 0.0002 inches for go\/no-go inspection use\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.2 pounds for easy single-hand use\u003c\/li\u003e\n  \u003cli\u003eSingle-piece unit packaged individually for direct use out of the box\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a Class ZZ minus plug pin gage for dimensional inspection of holes and bores nominally sized at 0.3460 inches in standard machining and quality control applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePin gages should be handled with clean, dry hands or lint-free gloves to prevent corrosion from skin oils. Before use, verify the gage and the workpiece bore are at a common reference temperature, typically 68 degrees F, to ensure measurement accuracy. Store the gage in its protective case when not in use to prevent surface damage that could affect dimensional accuracy. No power tools or mechanical force are required; hand insertion only.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter of Measurement\u003c\/strong\u003e: 0.3460 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches (0.0002 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage 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: 19-346-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51691607392562,"sku":"19-346-6","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7fdeee8d337c4aa65b8479ca15d0ebad.jpg?v=1788287722","url":"https:\/\/voomisupply.com\/products\/spi-19-346-6-class-zz-minus-plug-pin-gage-0-3460-in","provider":"Voomi Supply","version":"1.0","type":"link"}
