It attaches to the indicator spindle and provides a hardened steel ball tip for accurate surface contact during measurement work. The ball diameter is 0.078 inches (2.00 mm), and the overall contact point length is 0.812 inches. The steel construction delivers consistent wear resistance in repetitive gauging applications. This replacement contact point is typically installed by machinists, metrologists, toolroom technicians, and quality-control personnel working with precision measurement instruments.\u003c\/p\u003e\n\u003cp\u003eThis contact point is suited for bench measurement, fixture gauging, and machine tool inspection setups where a ball-tip stylus is preferred over a flat or pointed contact. It threads directly onto compatible test indicator spindles and is appropriate for both surface plate work and in-process inspection on manual or CNC machine tools. The compact ball tip allows contact on small bores, grooves, and contoured surfaces where larger tips would not seat properly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBall diameter of 0.078 inches (2.00 mm) for contact on small-radius and contoured features\u003c\/li\u003e\n  \u003cli\u003eOverall contact point length of 0.812 inches for standard reach applications\u003c\/li\u003e\n  \u003cli\u003eSteel construction for wear resistance in repetitive gauging cycles\u003c\/li\u003e\n  \u003cli\u003eReplacement-style fit for Interapid test indicators\u003c\/li\u003e\n  \u003cli\u003eSold individually, one contact point per package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Interapid test indicators as stated by the manufacturer.

Remove the indicator from service before changing the contact point to prevent stylus deflection from damaging the movement. Avoid overtightening, as excessive torque can distort the spindle threads on precision indicators. Confirm the contact point is fully seated and the indicator reads zero correctly before returning the instrument to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 0.078 inches (2.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Point Length\u003c\/strong\u003e: 0.812 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Diameter\u003c\/strong\u003e: 0.078 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 Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 21-052-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51723195613490,"sku":"21-052-6","price":20.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cc4f6a269558eb6f73e58ebd3b4a7cc6.jpg?v=1788601867","url":"https:\/\/voomisupply.com\/products\/spi-21-052-6-ball-contact-point-steel-interapid","provider":"Voomi Supply","version":"1.0","type":"link"}
