This locknut threads onto the collet chuck body and applies the clamping force needed to hold the collet and cutting tool firmly in place during operation. It measures 0.87 inches in width and length and 0.47 inches in height, making it a compact, low-profile component suited to the ER11 collet form factor. Machinists, CNC technicians, and tool crib personnel working with ER11 toolholding systems will use this part as a direct replacement when a locknut shows wear, damage, or thread stripping.\u003c\/p\u003e\n\u003cp\u003eThe ER11 collet locknut is used wherever ER11 collet chucks are installed, including CNC machining centers, manual milling machines, engraving machines, and high-speed routing spindles. It is appropriate for both light production and job-shop environments. The ER11 standard is one of the most widely used collet series in small-diameter toolholding, and this locknut fits that ecosystem directly. It is typically installed as a replacement component during routine toolholder maintenance or after a tooling crash that damages the existing nut.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDesigned for the ER11 collet series for direct fitment with standard ER11 chucks\u003c\/li\u003e\n  \u003cli\u003eCompact profile: 0.87 inches wide by 0.47 inches tall\u003c\/li\u003e\n  \u003cli\u003eSold individually, allowing single-unit replacement without purchasing excess hardware\u003c\/li\u003e\n  \u003cli\u003eCompatible with the ER11 collet system used across a wide range of CNC and manual spindle applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement locknut for ER11 series collet chucks used in CNC machining, engraving, and routing spindle applications that accept the ER11 collet standard.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or CNC technician. The spindle or chuck must be fully stopped and de-energized before removing or installing any collet hardware. Hand-thread the locknut onto the chuck body before applying a spanner wrench to achieve proper seating torque; avoid impact tools that can cross-thread or damage the nut face. Inspect collet taper seats and chuck threads for wear before reinstalling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Locknut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.87 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.87 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.47 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0462 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: 23291900\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SC84904705\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51710625906994,"sku":"SC84904705","price":38.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/61483c352478c53bc68acee6a32c7d97.jpg?v=1788468859","url":"https:\/\/voomisupply.com\/products\/value-collection-sc84904705-er11-collet-locknut","provider":"Voomi Supply","version":"1.0","type":"link"}
