The contact point features a 2.00 mm (0.078 inch) diameter steel ball tip and a total contact point length of 0.606 inches. Constructed from steel, it delivers the rigidity and wear resistance required for consistent, repeatable surface contact. This accessory is installed by machinists, metrology technicians, and quality control professionals who need reliable stylus components for their test indicator setups.\u003c\/p\u003e\n\u003cp\u003eThis contact point is suited for precision inspection and gauging tasks in machine shops, manufacturing facilities, and quality labs. It threads onto compatible test indicators to provide accurate deflection readings when checking runout, flatness, bore alignment, and other geometric tolerances. Its compact ball geometry makes it well suited for confined measurement areas and curved or irregular surface profiles where a standard flat contact point cannot maintain consistent contact.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBall tip diameter of 2.00 mm (0.078 inches) for precise point contact on curved and irregular surfaces\u003c\/li\u003e\n  \u003cli\u003eContact point length of 0.606 inches for standard reach in most dial test indicator applications\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and wear resistance during repeated measurement cycles\u003c\/li\u003e\n  \u003cli\u003eDesigned as a direct-fit replacement or spare stylus for Mitutoyo test indicators\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.1 pounds, minimizing added mass on the indicator arm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Mitutoyo test indicators as stated by the manufacturer.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by metrology technicians or machinist-level personnel familiar with dial test indicator maintenance. Before replacing the contact point, remove the indicator from any active measurement setup to avoid accidental deflection or damage to the indicator mechanism. Contact points typically thread into the indicator spindle by hand or with a light wrench — do not overtighten, as this can damage the spindle threads. Verify that the replacement contact point is fully seated and secure before returning the indicator 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: 2.00 mm (0.078 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Point Length\u003c\/strong\u003e: 0.606 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: 20-304-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51697431511346,"sku":"20-304-2","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a18f556c6d511cc4db30924c4f880ca5.jpg?v=1788351594","url":"https:\/\/voomisupply.com\/products\/spi-20-304-2-ball-contact-point-steel-mitutoyo-test-indicators","provider":"Voomi Supply","version":"1.0","type":"link"}
