It uses a Torx Plus T15P drive for positive engagement and reduced cam-out during tightening. The M3.5 thread size and 12.50 mm overall length make it a direct-fit fastener for compatible indexable milling systems. This screw is a consumable service part — technicians and toolroom machinists replace these routinely as part of insert changeovers and toolholder maintenance. Sold individually per package with a minimum order quantity of 10 units.\u003c\/p\u003e\u003cp\u003eThis lock screw is used in indexable milling applications where inserts must be clamped securely against cutting forces. It is appropriate for use in production machining environments, toolrooms, and job shops running indexable face mills, shoulder mills, or other insert-style milling cutters that use M3.5 countersunk lock screws with T15P Torx Plus drive geometry. The countersunk head seates flush with the toolholder pocket, keeping the clamping surface clear of the cutting zone.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eT15P Torx Plus drive for positive bit engagement and reduced fastener damage during insert changes\u003c\/li\u003e\n\u003cli\u003eM3.5 thread size for compatibility with indexable milling toolholder insert seats\u003c\/li\u003e\n\u003cli\u003eCountersunk head design seats flush within the toolholder pocket\u003c\/li\u003e\n\u003cli\u003e12.50 mm overall length sized for standard indexable insert clamping depth\u003c\/li\u003e\n\u003cli\u003eManufacturer catalog reference: C03512-T15P\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with indexable milling toolholders that accept M3.5 countersunk lock screws with a T15P Torx Plus drive.

Always de-energize and lock out the machine before accessing the spindle or toolholder. Use a calibrated T15P Torx Plus bit to avoid rounding the drive recess. Do not reuse visibly damaged or stretched lock screws, as fastener failure under cutting loads can damage the toolholder pocket.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eScrew Type\u003c\/strong\u003e: Lock Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Torx Plus\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTorx Size\u003c\/strong\u003e: T15P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Countersunk\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M3.5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 12.50 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndexable Tool Type\u003c\/strong\u003e: Milling\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardware Compatibility\u003c\/strong\u003e: Insert\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Catalog Number\u003c\/strong\u003e: C03512-T15P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 02440228\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51563684135218,"sku":"02440228","price":106.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4b32ab973d17d8bbdaf5b0457089f670_44e0e409-a624-46b0-9462-2a15639ed59b.jpg?v=1786501303","url":"https:\/\/voomisupply.com\/products\/seco-02440228-lock-screw-t15p-torx-plus-m3-5-milling-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
