It features a 6 mm ruby ball tip mounted on a stainless steel stem with an M2 threaded connection. The overall length is 10 mm, making it a compact stylus suited for measuring in confined geometries and tight-tolerance inspection routines. Ruby is the preferred ball material in CMM work because of its hardness, dimensional stability, and low wear rate during repetitive contact cycles. This stylus is installed by metrology technicians and quality control professionals performing dimensional inspection on manufactured parts.\u003c\/p\u003e\n\u003cp\u003eThis stylus is appropriate for use in both production-floor CMM setups and laboratory-grade inspection environments. The M2 thread is a standard connection size found on a wide range of CMM probe heads and stylus extension systems. The 6 mm ball diameter and 10 mm overall length suit applications where moderate ball size and short reach are needed, such as feature inspection on machined castings, stamped parts, and precision-machined components in aerospace, automotive, and general manufacturing settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e6 mm ruby ball tip for high hardness and low wear during repeated contact measurement\u003c\/li\u003e\n  \u003cli\u003e10 mm overall length provides compact reach for confined-space inspection\u003c\/li\u003e\n  \u003cli\u003eM2 threaded stem for compatibility with standard CMM probe heads and extension bars\u003c\/li\u003e\n  \u003cli\u003eStainless steel stem resists corrosion and provides dimensional stability\u003c\/li\u003e\n  \u003cli\u003e2.50 mm stem diameter balances stiffness and clearance in tight measurement zones\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use stylus for CMM systems accepting M2 threaded ball styli.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCMM styli are installed by qualified metrology technicians using the appropriate stylus wrench to avoid overtightening the M2 thread connection, which can damage the probe head seat or stylus stem. Before changing styli, power down or park the CMM probe head per the machine manufacturer's procedure to prevent collision damage. Handle the ruby ball carefully during installation, as impact or dropping can chip the ball and introduce measurement error. After installation, perform a qualification routine using the machine's reference sphere before committing the stylus to production inspection.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 6 mm (0.2362 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 10 mm (0.3937 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEffective Working Length\u003c\/strong\u003e: 10 mm (0.3937 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStem Diameter\u003c\/strong\u003e: 2.50 mm (0.0984 inches)\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\u003eStem Material\u003c\/strong\u003e: Stainless Steel\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: 2 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: RENISHAW\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: A-5000-4156\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RENISHAW","offers":[{"title":"Default Title","offer_id":67912011546930,"sku":"A-5000-4156","price":58.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6dfac5c233c9f57b68659db066ac511e.jpg?v=1791225121","url":"https:\/\/voomisupply.com\/products\/renishaw-a-5000-4156-cmm-ball-stylus-6mm-ruby-m2","provider":"Voomi Supply","version":"1.0","type":"link"}
