Manufactured from steel, this pin gage checks whether a hole falls within specified dimensional tolerances by using a go\/no-go verification method. The 19-161-9 measures 0.161 inches in diameter and holds a tolerance of 0.0002 inches, making it suitable for quality control inspections where close dimensional accuracy is required. Machinists, toolmakers, and inspection technicians use pin gages like this one during part verification, fixture setup, and incoming material inspection.\u003c\/p\u003e\n\u003cp\u003eThis gage is used in machine shops, manufacturing facilities, and maintenance environments wherever precise hole size verification is needed. It is appropriate for inspecting drilled, reamed, or punched holes in metal, plastic, or composite workpieces. The minus designation indicates the gage is ground to the lower limit of the nominal diameter, following standard Class ZZ gage practice for checking minimum hole size acceptance. Single-unit packaging makes it practical for bench-level inspection kits or individual replacement of worn gages.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.161 inch nominal diameter for direct bore verification at that dimension\u003c\/li\u003e\n  \u003cli\u003eClass ZZ tolerance grade with 0.0002 inch tolerance for reliable dimensional inspection\u003c\/li\u003e\n  \u003cli\u003eMinus designation ground to lower limit per standard Class ZZ gage protocol\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides durability and dimensional stability under normal shop conditions\u003c\/li\u003e\n  \u003cli\u003eSingle-piece packaging suitable for individual bench use or kit integration\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or supplemental gage for standard pin gage sets used in general industrial inspection of 0.161 inch nominal diameter holes.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePin gages are handled and used by machinists, quality technicians, and toolmakers during inspection procedures rather than installation. Clean the gage and the bore to be checked before use to prevent debris from affecting readings. Store the gage in a protective case when not in use to avoid damage to the ground surface. Do not force the gage into a hole, as this can cause galling or alter the calibrated diameter.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.161 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\u003eGage Class\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  \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: 19-161-9\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51719310836018,"sku":"19-161-9","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/75fc3a4c2961ac220c8427c8f5c388c3.jpg?v=1788558754","url":"https:\/\/voomisupply.com\/products\/spi-19-161-9-class-zz-minus-plug-pin-gage-0-161-in","provider":"Voomi Supply","version":"1.0","type":"link"}
