It features a 0.093 inch ball diameter and a contact point length of 0.688 inches, making it suitable for precise measurement tasks in tight or curved surface applications. The carbide construction provides excellent wear resistance, maintaining accuracy over repeated use. This contact point is a standard replacement or alternate-geometry accessory installed by machinists, tool-and-die technicians, and metrology professionals working in manufacturing, inspection, or quality control environments.\u003c\/p\u003e\u003cp\u003eThis contact point is used in dimensional inspection setups where a ball-style tip is required to contact curved, recessed, or small-diameter surfaces. It is compatible with Interapid test indicators and suits bench inspection, fixture setup, and in-process measurement work. The compact dimensions make it effective in confined measurement zones where a standard flat or pointed tip would not seat correctly.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCarbide ball tip for extended wear life and consistent contact geometry\u003c\/li\u003e\n\u003cli\u003e0.093 inch ball diameter for contact on small or curved surfaces\u003c\/li\u003e\n\u003cli\u003e0.688 inch contact point length suits typical Interapid indicator reach\u003c\/li\u003e\n\u003cli\u003eDirect replacement contact point requiring no modification for installation\u003c\/li\u003e\n\u003cli\u003eSold individually for single-point replacement or kit customization\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 for test indicators are installed and removed by hand or with a small wrench, depending on the indicator model. Power-down and lockout procedures are not typically required for metrology tooling, but ensure the indicator is removed from any active fixture or machine before swapping contact points. Avoid overtightening the contact point thread, as this can damage the indicator spindle. Consult the indicator manufacturer documentation for the correct thread specification and torque guidance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 0.093 inches (2.40 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\u003eTip Diameter\u003c\/strong\u003e: 0.093 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Point Material\u003c\/strong\u003e: Carbide\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\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: 21-057-5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51720378974514,"sku":"21-057-5","price":19.07,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c082cedd4f7d235bd9e0301ccf3dd5a1.jpg?v=1788563022","url":"https:\/\/voomisupply.com\/products\/spi-21-057-5-ball-contact-point-carbide-interapid","provider":"Voomi Supply","version":"1.0","type":"link"}
