It measures 0.935 inches in diameter and is manufactured from steel for durability in shop floor conditions. Class ZZ is the commercial-grade tolerance class for pin gages, suited to general inspection work where ultra-precision master-grade accuracy is not required. The minus designation means the gage is ground to the lower boundary of the tolerance band, making it a go or no-go reference depending on inspection protocol. A tolerance of 0.000200 inches ensures consistent, repeatable measurement results. Machinists, tool and die technicians, and quality control inspectors are the primary users of this gage type.\u003c\/p\u003e\n\u003cp\u003eThis plug pin gage is used in production and inspection environments where bore diameter must be confirmed against a fixed go or no-go specification. Typical applications include verifying drilled, reamed, or bored holes in metal and plastic workpieces during incoming inspection, in-process checks, or final quality verification. It is well suited to machine shops, maintenance shops, and manufacturing lines where quick manual attribute gauging is preferred over air gauging or coordinate measuring machine verification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ commercial-grade tolerance class for general-purpose hole inspection\u003c\/li\u003e\n  \u003cli\u003eMinus designation grounds gage to the lower tolerance boundary for defined go or no-go use\u003c\/li\u003e\n  \u003cli\u003e0.000200 inch tolerance for consistent, repeatable attribute measurement\u003c\/li\u003e\n  \u003cli\u003eSteel construction for wear resistance in production environments\u003c\/li\u003e\n  \u003cli\u003e0.935 inch diameter covers a common bore size range in general machining work\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.2 pounds for easy single-hand use\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 any manual attribute inspection process requiring verification of a 0.935 inch nominal bore diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePin gages are inspection tools and do not require installation, but proper handling extends service life and maintains accuracy. Store the gage in a protective case away from other metal tools to prevent nicking or corrosion on the ground surface. Before use, clean both the gage and the bore being checked with a lint-free cloth to remove chips, oil, or debris that could cause false readings. Never force the gage into a bore; if resistance is felt, check for burrs or obstructions before proceeding.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 0.935 inches\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\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: 19-935-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51711927025970,"sku":"19-935-6","price":16.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/562c7907c766b73169d8450cfc443590.jpg?v=1788481480","url":"https:\/\/voomisupply.com\/products\/spi-19-935-6-class-zz-minus-plug-pin-gage-0-935-in","provider":"Voomi Supply","version":"1.0","type":"link"}
