It features a 0.015 inch ball diameter and a contact point length of 0.688 inches. Carbide construction provides the hardness and wear resistance needed for repeated contact measurement tasks in precision inspection environments. This replacement contact point is installed by machinists, quality control technicians, and metrology professionals who require accurate stylus geometry for surface and bore measurement work.\u003c\/p\u003e\u003cp\u003eThis contact point is suited for precision measurement applications where a small ball tip is needed to reach tight tolerances, grooves, or contoured surfaces. It is compatible with Interapid test indicators and is a common replacement item in inspection departments, machine shops, and toolrooms working to close dimensional tolerances.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.015 inch carbide ball diameter for small-feature contact measurement\u003c\/li\u003e\n\u003cli\u003e0.688 inch contact point length for reach into confined areas\u003c\/li\u003e\n\u003cli\u003eCarbide tip material resists wear and maintains accurate geometry over repeated use\u003c\/li\u003e\n\u003cli\u003eDesigned as a direct replacement for Interapid test indicator stylus assemblies\u003c\/li\u003e\n\u003cli\u003eCompact and lightweight at 0.1 pounds\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 point replacement is performed by metrology or inspection personnel using standard indicator wrench tools. Power down or isolate any CNC or automated equipment before accessing mounted indicators. Avoid overtightening the contact point thread, as carbide tips can be damaged by excessive torque. Handle the ball tip carefully to prevent chipping, which would compromise measurement accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 0.015 inches (0.40 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: 0.015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Point Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFor Use With\u003c\/strong\u003e: Interapid Test Indicators\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\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: 21-053-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51710494310706,"sku":"21-053-4","price":26.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dcf2b197441b47fe51fb64354759bbb7.jpg?v=1788467594","url":"https:\/\/voomisupply.com\/products\/spi-21-053-4-ball-contact-point-carbide-interapid","provider":"Voomi Supply","version":"1.0","type":"link"}
