The hex profile allows for positive tightening with a standard spanner or locknut wrench, ensuring consistent clamping force and accurate tool runout. This locknut does not support coolant-through configurations. It is a direct replacement component intended for machinists and tooling technicians maintaining or rebuilding ER16 collet chuck assemblies in CNC and manual machining environments.\u003c\/p\u003e\n\u003cp\u003eThis locknut is suited for use in production machine shops, tool rooms, and maintenance environments where ER16 collet holders are in regular service. It is commonly installed when an existing locknut shows wear, thread damage, or inconsistent clamping performance. The ER16 collet series is widely used in milling, drilling, and light turning applications across both CNC machining centers and manual mills.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHex profile for positive tightening with a spanner or locknut wrench\u003c\/li\u003e\n  \u003cli\u003eCompatible with ER16 collet series tool holders\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through passage  -  suited for dry or flood coolant setups without through-spindle coolant\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.1 pounds  -  minimal added mass to tool assembly\u003c\/li\u003e\n  \u003cli\u003eDirect OEM-style replacement for worn or damaged ER16 locknuts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement locknut for ER16 collet series tool holders.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Power down and de-energize the spindle completely before servicing any collet chuck assembly. Use the correct ER16 spanner wrench to achieve proper clamping torque  -  do not use improvised tools that may damage the hex profile or thread. Inspect collet and holder threads for wear or contamination before installing the replacement locknut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Hex Locknut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: TECHNIKS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 11116\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TECHNIKS","offers":[{"title":"Default Title","offer_id":51994117407026,"sku":"11116","price":42.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7d82b1eccb37edc6b8092d172e76baa7_b0b8beb3-5d6c-4398-8922-2ac96ee9a7ba.jpg?v=1789991662","url":"https:\/\/voomisupply.com\/products\/techniks-11116-er16-hex-collet-locknut","provider":"Voomi Supply","version":"1.0","type":"link"}
