It features a 0.031-inch ball diameter and a contact point length of 1.45 inches. The carbide tip provides wear resistance and dimensional stability during precision measurement work. This contact point is a replacement or spare accessory used by machinists, metrologists, and quality control technicians to maintain accuracy in surface and bore runout measurements. Its small ball diameter makes it well-suited for fine-detail inspection tasks where standard contact points are too large for the feature being measured.\u003c\/p\u003e\u003cp\u003eThis contact point is intended for use in machine shops, tool rooms, and inspection departments where Interapid test indicators are part of the standard measurement toolkit. It fits into setups for checking runout, concentricity, flatness, and similar precision measurements on machined parts. The 0.031-inch ball diameter allows access to small bores, grooves, and tight geometry that larger contact points cannot reach reliably.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCarbide ball tip for extended wear resistance during repeated contact measurements\u003c\/li\u003e\n\u003cli\u003e0.031-inch (0.80 mm) ball diameter for fine-detail and small-feature inspection\u003c\/li\u003e\n\u003cli\u003e1.45-inch contact point length for reach in confined measurement setups\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 storage\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\u003eInstallation is performed by machinists or metrology technicians using standard contact point threading procedures for Interapid-style indicators. Ensure the indicator is removed from any active measurement setup before swapping contact points. Avoid applying side-load force when threading the contact point to prevent damage to the indicator stem or contact point threads. Handle carbide-tipped contact points carefully to avoid chipping the tip against hard surfaces.\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: 1.45 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Point Material\u003c\/strong\u003e: Carbide\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\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: 21-061-7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51692045992242,"sku":"21-061-7","price":20.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5cc8ff94de251456b0402fc7627063f3.jpg?v=1788292361","url":"https:\/\/voomisupply.com\/products\/spi-21-061-7-ball-contact-point-carbide-interapid","provider":"Voomi Supply","version":"1.0","type":"link"}
