It threads into the indicator spindle and provides the physical tip that contacts the workpiece surface during measurement. The ball tip measures 0.031 inches in diameter, and the overall contact point length is 0.688 inches. Fabricated from steel for durability in shop and inspection environments, this contact point is a direct replacement or spare component installed by machinists, tool and die makers, and metrology technicians performing precision measurement tasks.\u003c\/p\u003e\u003cp\u003eThis contact point is suited for use in machine shops, quality control labs, and inspection stations where dial test indicators are used to measure runout, surface variation, and part alignment. Its small ball diameter allows contact on tight radii and contoured surfaces where a flat or chisel-style tip would not seat accurately. It is compatible with Interapid test indicators as specified by the manufacturer.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBall tip diameter of 0.031 inches for precise contact on small or contoured surfaces\u003c\/li\u003e\n\u003cli\u003eOverall contact point length of 0.688 inches\u003c\/li\u003e\n\u003cli\u003eSteel construction for wear resistance in production and inspection environments\u003c\/li\u003e\n\u003cli\u003eDesigned for use with Interapid test indicators\u003c\/li\u003e\n\u003cli\u003eCompact and lightweight at 0.1 pounds for easy handling and installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Interapid test indicators as stated by the manufacturer.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eContact points are installed and removed by threading into or out of the indicator spindle — power down or remove any associated equipment before handling precision measuring instruments to avoid accidental drops or damage. Use the appropriate wrench or contact point tool to avoid marring the tip or spindle threads. Handle the ball tip carefully to prevent nicks that could affect measurement accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 0.031 inches (0.80 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Point Length\u003c\/strong\u003e: 0.688 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Point Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 1 inches x 0.25 inches x 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111600\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: 21-047-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51694602682674,"sku":"21-047-6","price":15.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d8935c550167890e90db7f30aa96b0e.jpg?v=1788326105","url":"https:\/\/voomisupply.com\/products\/spi-21-047-6-test-indicator-ball-contact-point-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
