It features a 2 mm ruby ball tip mounted on an M2 threaded shank with an overall length of 20 mm. Ruby is the standard point material for CMM styli due to its hardness, dimensional consistency, and low coefficient of friction against most workpiece surfaces. This stylus is installed by metrologists, quality technicians, and dimensional inspection professionals working in manufacturing and metrology environments.\u003c\/p\u003e\n\u003cp\u003eThis stylus is suited for general-purpose coordinate measuring machine inspection tasks, including surface scanning, bore measurement, and feature location on precision machined components. The M2 thread interface is a widely used connection standard in CMM stylus systems, making this part compatible with a broad range of CMM probe modules and extension configurations used in industrial quality control settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2 mm ruby ball tip for high-hardness, low-wear contact measurement\u003c\/li\u003e\n  \u003cli\u003eM2 threaded shank for standard CMM probe and extension compatibility\u003c\/li\u003e\n  \u003cli\u003e20 mm overall length suits shallow-to-moderate reach inspection applications\u003c\/li\u003e\n  \u003cli\u003eRuby point material provides consistent form accuracy across repeated measurement cycles\u003c\/li\u003e\n  \u003cli\u003eCompact form factor minimizes stylus deflection during contact\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or spare stylus for CMM systems accepting M2-threaded ball styli. Confirm thread pitch and probe head torque specifications with your CMM manufacturer before installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCMM styli are installed by qualified metrology or inspection technicians. Power down or set the CMM to a safe parked state before changing styli to prevent probe crashes or calibration errors. Use the appropriate stylus wrench and the torque specification recommended by the CMM probe head manufacturer — do not overtighten, as M2 threads are fine and the stylus shank can fracture. After installation, always run a full calibration or qualification routine on a reference sphere before resuming inspection tasks.\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\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\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: Z3862\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51694525546802,"sku":"Z3862","price":320.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/99d42da7ea0c107bb263e5b77c6abaf8.jpg?v=1788325049","url":"https:\/\/voomisupply.com\/products\/spi-z3862-cmm-ball-stylus-2mm-m2-ruby-point","provider":"Voomi Supply","version":"1.0","type":"link"}
