It features a 2 mm ruby ball tip mounted on an M2-threaded stem with an overall length of 20 mm. The ruby point material provides excellent hardness and low friction contact, supporting repeatable, accurate measurements across successive probing cycles. This stylus is installed by metrology technicians, quality control engineers, and calibration specialists working in manufacturing, inspection, and tooling environments.\u003c\/p\u003e\n\u003cp\u003eThe Z3100 is suited for use in tight-tolerance dimensional inspection setups where a compact, lightweight stylus is required. The M2 thread interface is a widely used standard in CMM probing systems, making this stylus compatible with a broad range of touch-trigger and scanning probe bodies that accept M2 connections. It is commonly used in production inspection of machined components, castings, and fabricated parts where surface contact measurement is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2 mm ruby ball tip for hard, wear-resistant contact surface\u003c\/li\u003e\n  \u003cli\u003eM2 thread on both stylus and probe interface for secure, repeatable mounting\u003c\/li\u003e\n  \u003cli\u003e20 mm overall length suits shallow-reach and standard inspection tasks\u003c\/li\u003e\n  \u003cli\u003eRuby point material minimizes stylus wear during high-cycle measurement routines\u003c\/li\u003e\n  \u003cli\u003eLightweight construction reduces probe head loading and measurement error\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or supplemental stylus for CMM probe systems accepting M2-threaded ball styli.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCMM styli should be installed and changed by qualified metrology personnel following the CMM manufacturer's recommended procedures. Power down or place the CMM in a safe parked state before changing styli to avoid probe head damage. Use the appropriate stylus wrench or tool recommended by the probe manufacturer — hand-tightening only is standard practice, as overtightening M2 threads can damage the probe body or stylus shank. Perform a qualification routine on the reference sphere after every stylus change before resuming measurement programs.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 2 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 20 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStylus Thread Size\u003c\/strong\u003e: M2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProbe Thread Size\u003c\/strong\u003e: M2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStylus Type\u003c\/strong\u003e: Ball\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Material\u003c\/strong\u003e: Ruby\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.38 pounds\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: Z3100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51700006486322,"sku":"Z3100","price":75.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/35c9d2426157aa71c77cecd216633475.jpg?v=1788384869","url":"https:\/\/voomisupply.com\/products\/spi-z3100-cmm-ball-stylus-2mm-ruby-point-m2-thread","provider":"Voomi Supply","version":"1.0","type":"link"}
