Class ZZ gages are manufactured to a minus tolerance of 0.0002 inches, meaning the gage is intentionally sized slightly under nominal to serve as a go or no-go reference in dimensional inspection work. Machinists, quality control technicians, and tool room personnel use plug pin gages as fast, reliable gauging tools when checking hole acceptance during production or incoming inspection.\u003c\/p\u003e\n\u003cp\u003eThis pin gage is suited for use in machine shops, manufacturing facilities, and quality inspection environments where hole diameter verification is required. It is appropriate for checking bores in metal or hard plastic components where a 0.788-inch nominal diameter is specified. The minus tolerance classification makes it useful as a go-gage reference in standard gauging practice. This gage is sold individually and is compatible with standard gage handle sets used to hold plug-style pin gages during inspection tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ tolerance grade with 0.0002-inch minus tolerance for reliable dimensional verification\u003c\/li\u003e\n  \u003cli\u003e0.788-inch nominal diameter for direct bore and hole checking\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and dimensional stability in shop environments\u003c\/li\u003e\n  \u003cli\u003eMinus plug style suited for use as a go-gage reference in standard gauging workflows\u003c\/li\u003e\n  \u003cli\u003eSold as a single gage unit for individual hole size verification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard plug pin gage handles sized to accept 0.788-inch diameter pin gages.

Before use, verify the gage is clean and free of burrs or contamination that could produce false readings. Store in a protective case away from other metal tooling to prevent surface damage. Calibration intervals should follow the quality system requirements applicable to your facility.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.788 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\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\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 19-788-9\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51692857000242,"sku":"19-788-9","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e40c39fc2d64ab7faed3bcac68555ea4.jpg?v=1788304115","url":"https:\/\/voomisupply.com\/products\/spi-19-788-9-class-zz-minus-plug-pin-gage-0-788-in","provider":"Voomi Supply","version":"1.0","type":"link"}
