The hex profile allows standard wrench engagement for consistent clamping torque during setup and changeover. This locknut is a direct-replacement style component used in CNC machining, milling, and turning applications where ER16 collet chucks are standard. Machinists and tooling technicians install this part as part of routine collet maintenance or when replacing worn or damaged locknuts on ER16 toolholders.\u003c\/p\u003e\u003cp\u003eThe 41116 is suited for ER16 collet chuck assemblies found in CNC machining centers, manual milling machines, and high-speed spindle applications. It is appropriate for production shops, tool rooms, and maintenance environments where ER16 tooling is regularly cycled and locknuts experience wear over time. Installation requires no special equipment beyond a standard ER collet wrench.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHex profile for positive wrench engagement during tightening and removal\u003c\/li\u003e\n\u003cli\u003eCompatible with ER16 collet series toolholders\u003c\/li\u003e\n\u003cli\u003eSold individually, allowing single-unit replacement without buying in bulk\u003c\/li\u003e\n\u003cli\u003eLightweight construction at 0.2 pounds for easy handling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with ER16 series collet chucks and toolholders that accept standard ER16 locknuts.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician familiar with ER collet systems. Ensure the spindle or toolholder is fully stopped and de-energized before removing or installing the locknut. Use a proper ER collet wrench to achieve appropriate clamping engagement without over-torquing. Inspect the collet and toolholder threads for wear or damage before reinstalling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 41116\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TECHNIKS","offers":[{"title":"Default Title","offer_id":52046764802354,"sku":"41116","price":69.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/60e7b3b5e445feaffa5b765150fdb654.jpg?v=1790031484","url":"https:\/\/voomisupply.com\/products\/techniks-41116-er16-hex-collet-locknut","provider":"Voomi Supply","version":"1.0","type":"link"}
