At 0.234 inches in diameter, this gage holds a tolerance of 0.0002 inches, conforming to Class ZZ standards for plain cylindrical plug gages. It is used in dimensional inspection to confirm that a workpiece bore is at or above the minimum specified diameter. Machinists, quality control technicians, and toolroom personnel are the primary users of this gage in production and inspection environments.\u003c\/p\u003e\n\u003cp\u003eThis pin gage is suited for shop-floor and laboratory inspection of precision bored or drilled holes in both light manufacturing and high-tolerance machining operations. It is typically handled as part of a go\/no-go gage set or used individually to check a single critical bore dimension. The minus designation means the gage is manufactured at the lower end of the nominal diameter, making it the go member in standard plug gage practice.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ tolerance class for general-purpose inspection of standard-tolerance bores\u003c\/li\u003e\n  \u003cli\u003eMinus designation confirms the gage is manufactured below nominal for go-member applications\u003c\/li\u003e\n  \u003cli\u003e0.0002 inch tolerance ensures repeatable, accurate bore verification\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides durability for repeated use in production environments\u003c\/li\u003e\n  \u003cli\u003e0.234 inch nominal diameter covers a common bore size range in machined components\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 compatible gage handle sets and in go\/no-go inspection stations requiring a 0.234 inch nominal bore check.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis gage is handled by quality control or toolroom personnel and does not require power or mechanical installation. Before use, clean both the gage and the bore to be inspected to remove chips, oil, or debris that could affect the reading. Store the gage in a protective case away from temperature extremes to maintain dimensional stability and prevent corrosion. Follow your facility's gage calibration schedule to ensure continued measurement accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.234 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance 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: 19-234-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51691988255026,"sku":"19-234-4","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/36aecb7d9674aabcb71ce65b328f605d.jpg?v=1788291772","url":"https:\/\/voomisupply.com\/products\/spi-19-234-4-class-zz-minus-plug-pin-gage-0-234-in","provider":"Voomi Supply","version":"1.0","type":"link"}
