It features a 4 mm ruby ball tip threaded onto an M2 stem with a 20 mm overall length. Ruby is the standard point material for CMM styli due to its hardness, wear resistance, and consistent spherical geometry, which minimizes measurement error over repeated contact cycles. This stylus is installed and used by metrology technicians, quality control engineers, and precision manufacturing professionals operating CMM equipment in industrial inspection environments.\u003c\/p\u003e\n\u003cp\u003eThe Z3400 suits a wide range of contact-scanning and touch-trigger CMM applications in manufacturing and quality assurance settings. Its compact 20 mm overall length and 4 mm ball diameter make it appropriate for general-purpose surface and bore measurement where moderate reach is needed without excessive stylus deflection. It is suitable for use in both high-volume production inspection and precision toolroom measurement workflows.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4 mm ruby ball tip for consistent contact geometry and extended wear life\u003c\/li\u003e\n  \u003cli\u003eM2 threaded stem for compatibility with standard CMM stylus holders and extensions\u003c\/li\u003e\n  \u003cli\u003e20 mm overall length provides moderate reach for general-purpose measurement tasks\u003c\/li\u003e\n  \u003cli\u003eLightweight construction at 0.38 pounds minimizes spindle load and deflection error\u003c\/li\u003e\n  \u003cli\u003eSingle-piece packaging suitable for individual replacement or spare inventory\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard M2-thread replacement ball stylus for use with touch-trigger and scanning CMM probes that accept M2 stylus connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCMM styli should be installed and qualified by trained metrology personnel following the CMM manufacturer's calibration and qualification procedures. Handle the ruby ball carefully during installation to avoid chipping, which will invalidate measurement accuracy. Ensure the M2 thread is engaged smoothly by hand before using any tool, and do not overtighten, as excessive torque can fracture the stylus stem or damage the probe head. Re-qualify the stylus in the CMM software after any installation or replacement.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 4 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 20 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Material\u003c\/strong\u003e: Ruby\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStylus Type\u003c\/strong\u003e: Ball\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.38 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111900\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: Z3400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51706379534642,"sku":"Z3400","price":98.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/55eed6176151a48f50467f4f476357f3.jpg?v=1788434083","url":"https:\/\/voomisupply.com\/products\/spi-z3400-cmm-ball-stylus-4mm-ruby-point-m2-thread","provider":"Voomi Supply","version":"1.0","type":"link"}
