Built from steel, this go-type gage checks that a feature is at or above its minimum allowable size. At 0.938 inches in diameter, it is sized for mid-range bore inspection work. The minus designation indicates the gage is manufactured to the low side of tolerance, conforming to Class ZZ standards for general-purpose dimensional inspection. Machinists, quality control technicians, and tool room personnel use plug gages like this one to confirm hole conformance during production or incoming inspection.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for use in machine shops, tool rooms, and quality inspection stations where hole diameter verification is part of a standard workflow. Class ZZ plug gages are commonly applied in general manufacturing environments where tolerance requirements are less stringent than Class Z or ZZ-plus applications. The 0.938-inch diameter makes it appropriate for inspecting drilled, reamed, or bored holes in metal, plastic, or composite workpieces. It is typically used as a handheld inspection tool and does not require fixturing or power.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ minus designation for general-purpose go-type bore inspection\u003c\/li\u003e\n  \u003cli\u003e0.938 inch diameter for mid-range hole and bore verification\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in shop-floor inspection environments\u003c\/li\u003e\n  \u003cli\u003eTolerance of 0.0002 inches, conforming to Class ZZ gage-making standards\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.2 pounds for comfortable handheld use\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 suitable for general-purpose bore inspection of 0.938-inch diameter holes in typical machining and quality control applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug pin gages are handheld inspection tools and do not require installation. Before use, clean the gage and the bore being checked to remove chips, coolant, or debris that could affect the reading. Apply light gage oil when checking ferrous workpieces to prevent corrosion and reduce wear on the gage surface. Store in a protective case away from heat sources to maintain dimensional stability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 0.938 inches\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\u003eClass\u003c\/strong\u003e: 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: 19-938-0\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51697375707442,"sku":"19-938-0","price":16.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/da5b8626a7f77eb2d2bcbb4cc5a2be97.jpg?v=1788351178","url":"https:\/\/voomisupply.com\/products\/spi-19-938-0-class-zz-minus-plug-pin-gage-0-938-in","provider":"Voomi Supply","version":"1.0","type":"link"}
