Manufactured from steel, this nut provides the clamping force required to seat ER20 collets securely within compatible toolholders. The hex profile allows installation and removal with a standard HI-Q spanner, making it a practical service replacement for machine shops and tooling technicians maintaining ER-style chuck assemblies. It weighs 0.133 pounds and ships as a single unit.\u003c\/p\u003e\n\u003cp\u003eThis collet nut is intended for use in ER20 collet chuck toolholders found on CNC machining centers, milling machines, lathes with live tooling, and similar precision machining equipment. It is a direct replacement component suited for maintenance situations where the existing nut shows wear, thread damage, or bearing surface deterioration that compromises clamping performance. Installation requires a HI-Q spanner wrench sized for ER20 hex nuts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER20 collet series compatibility for broad toolholder fitment\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability under repeated torque cycles\u003c\/li\u003e\n  \u003cli\u003eHex profile designed for use with HI-Q spanner wrench\u003c\/li\u003e\n  \u003cli\u003eSingle-piece replacement unit  -  no coolant-through capability\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.133 pounds for minimal spindle load contribution\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement hex collet nut for ER20 collet series toolholders.

Thread the collet nut onto the toolholder body by hand before applying a HI-Q spanner to achieve proper seating torque. Inspect the nut bearing surface and threads for wear before reinstalling; damaged threads can cause collet runout and workpiece inaccuracy. Follow the toolholder manufacturer's recommended torque specification for the ER20 nut size.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Hex Collet Nut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFor Use With\u003c\/strong\u003e: HI-Q Spanner\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.133 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: REGO-FIX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3420.00000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"REGO-FIX","offers":[{"title":"Default Title","offer_id":67906033877298,"sku":"3420.00000","price":73.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d007f30d2be8c5e41c576bc7a4bf5856.jpg?v=1791163411","url":"https:\/\/voomisupply.com\/products\/rego-fix-3420-00000-er20-hex-collet-nut","provider":"Voomi Supply","version":"1.0","type":"link"}
