Pin gages are precision measuring tools used to verify hole diameters, slot widths, and other critical dimensional features on machined or fabricated workpieces. The minus designation means the gage is manufactured to the lower allowable tolerance boundary, confirming that a hole is at or above the minimum acceptable size. Constructed from steel, this gage is a standard go\/no-go reference instrument for inspection and quality control work in machine shops, fabrication facilities, and manufacturing environments.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is suited for dimensional inspection tasks where tight hole tolerances must be verified quickly and reliably. It is commonly used by machinists, quality control inspectors, and toolroom personnel working with precision bored, drilled, or reamed holes. The 0.542-inch diameter falls within a common range for general metalworking and light industrial inspection applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal diameter of 0.542 inches for precise hole verification\u003c\/li\u003e\n  \u003cli\u003eClass ZZ tolerance grade rated for general inspection use\u003c\/li\u003e\n  \u003cli\u003eMinus plug configuration checks minimum acceptable hole size\u003c\/li\u003e\n  \u003cli\u003eTolerance of 0.0002 inches for reliable dimensional accuracy\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in shop environments\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 general-purpose dimensional inspection of 0.542-inch nominal diameter holes in machined components and assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePin gages are hand-held inspection tools and do not require installation. Always clean and deburr the hole being checked before inserting the gage to avoid damage to the gage surface. Handle with clean, dry hands or cotton gloves to prevent corrosion from skin contact. Store in a protective case away from other metal tools to maintain gage accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.542 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Class\u003c\/strong\u003e: Class ZZ\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlug Type\u003c\/strong\u003e: Minus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches\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: 19-542-0\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51691091231026,"sku":"19-542-0","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a29329c67d50fbe212ffe3d6bdf4a954.jpg?v=1788280237","url":"https:\/\/voomisupply.com\/products\/spi-19-542-0-class-zz-minus-plug-pin-gage-0-542-in","provider":"Voomi Supply","version":"1.0","type":"link"}
