The nut threads onto the tool holder nose and applies clamping force to the collet, holding cutting tools concentrically under load. At 0.5 pounds, it is a compact, single-piece component suited for high-speed spindle applications where secure tool retention is critical. Machinists, CNC operators, and tooling technicians install and replace these nuts as part of routine tooling maintenance or when thread wear affects clamping performance.\u003c\/p\u003e\u003cp\u003eThis clamping nut is used in machine shop and manufacturing environments wherever ER16 collet chucks are in service. Typical applications include vertical machining centers, CNC lathes with live tooling, and benchtop milling machines running ER16 tooling systems. The ER16 collet series accommodates smaller-diameter tool shanks and is common in precision light-duty cutting operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDesigned for ER16 collet series tool holders\u003c\/li\u003e\n\u003cli\u003eApplies consistent clamping force to retain cutting tools during operation\u003c\/li\u003e\n\u003cli\u003eSingle-piece replacement component for worn or damaged collet nuts\u003c\/li\u003e\n\u003cli\u003eCompact and lightweight at 0.5 pounds for use in space-limited spindle noses\u003c\/li\u003e\n\u003cli\u003eSold individually for precise inventory replenishment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replacement clamping nut for ER16 series collet chucks and tool holders. Compatible fitment is limited to tool holders machined to the ER16 collet standard.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC tooling technicians. Before replacing the collet nut, power down and lock out the machine spindle per OSHA lockout\/tagout procedures. Use the appropriate ER16 collet nut spanner wrench to achieve proper seating torque — do not use pliers or improvised tools, as uneven clamping can cause runout. Inspect the tool holder threads for wear or damage before installing the new nut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Clamping Nut\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ISCAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4513002\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51755168694578,"sku":"4513002","price":68.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e087e1f108e406e031b9c1faca84c781.jpg?v=1788951767","url":"https:\/\/voomisupply.com\/products\/iscar-4513002-er16-clamping-collet-nut","provider":"Voomi Supply","version":"1.0","type":"link"}
