With a nominal diameter of 0.775 inches and a minus tolerance of 0.000200 inches, this gage checks whether a bore or hole falls within the required dimensional limits. The steel construction provides wear resistance and dimensional stability under repeated use. Machinists, quality control technicians, and toolroom personnel use Class ZZ pin gages as part of incoming inspection, in-process verification, and final acceptance routines in manufacturing environments.\u003c\/p\u003e\n\u003cp\u003eClass ZZ pin gages are the standard working-grade gage for general shop use and inspection of production parts. This 0.775-inch diameter gage is suited for checking clearance holes, bores, and similar features in metal, plastic, or composite workpieces. The minus designation means the gage is ground to the lower limit of the nominal diameter, making it appropriate for go or no-go inspection procedures where tight dimensional control is required. It is commonly used in job shops, OEM production lines, and quality labs handling mid-range hole sizes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal diameter of 0.775 inches for direct hole-size verification\u003c\/li\u003e\n  \u003cli\u003eClass ZZ tolerance grade suitable for general-purpose shop and inspection use\u003c\/li\u003e\n  \u003cli\u003eMinus tolerance of 0.000200 inches ground to the lower nominal limit\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and dimensional stability under repeated use\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.2 pounds for easy handling at the machine or inspection bench\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 0.775-inch nominal diameter holes and bores in production and quality control applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePin gages are used by quality control technicians and machinists and require no installation in the traditional sense. Clean the gage and the workpiece bore before use to prevent debris from affecting the reading. Store pin gages in their original case or a protected holder to avoid surface damage that could compromise accuracy. Periodic calibration against a certified master or traceable standard is recommended to maintain measurement integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.775 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: 0.000200 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\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: 19-775-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51696584524082,"sku":"19-775-6","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2dd2672d18bb2fc2fde955fe1fe79c1f.jpg?v=1788344244","url":"https:\/\/voomisupply.com\/products\/spi-19-775-6-class-zz-minus-plug-pin-gage-0-775-in","provider":"Voomi Supply","version":"1.0","type":"link"}
