This gage carries a tolerance of 0.0002 inches, placing it in the Class ZZ category suited for general inspection work where moderate precision is required. Plug pin gages are go\/no-go inspection tools used to confirm that drilled, reamed, or bored holes fall within acceptable dimensional limits. Machinists, quality control technicians, and toolroom personnel use these gages as part of standard incoming and in-process inspection routines on the shop floor.\u003c\/p\u003e\u003cp\u003eThis 0.176-inch diameter pin gage is appropriate for use in manufacturing environments, machine shops, and quality inspection departments. It is used to check hole sizes in metal, plastic, or composite workpieces where dimensional conformance to print is required. The minus designation indicates the gage is ground to the lower boundary of the nominal size, functioning as a go gage to confirm minimum acceptable hole diameter. It fits into standard gage handle sets compatible with wire gage pins in this size range.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eClass ZZ tolerance classification for general-purpose hole inspection\u003c\/li\u003e\n\u003cli\u003eMinus designation ground to lower size boundary for go-gage function\u003c\/li\u003e\n\u003cli\u003e0.0002 inches tolerance for reliable dimensional verification\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability in production and toolroom environments\u003c\/li\u003e\n\u003cli\u003e0.176 inches nominal diameter for precise small-hole gauging\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard wire-size plug pin gage compatible with typical gage handle sets that accept pin gages in the 0.176-inch diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePlug pin gages should be handled with clean, dry hands or lint-free gloves to prevent corrosion from skin oils. Ensure the workpiece hole is free of chips, burrs, and coolant before gauging. Apply light axial pressure only — forcing the pin can cause damage to the gage or the workpiece. Store in a protective case away from abrasive surfaces to maintain calibration.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.176 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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 19-176-7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51689020948786,"sku":"19-176-7","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c07b0a2d56e3dff0542a2e7715d4e82f.jpg?v=1788253934","url":"https:\/\/voomisupply.com\/products\/spi-19-176-7-class-zz-minus-plug-pin-gage-0-176-in","provider":"Voomi Supply","version":"1.0","type":"link"}
