It uses a Torx Plus TP20 drive and an M4.5 thread, requiring a T20P-3 key driver for installation and removal. At 10 millimeters overall length and a weight of 0.03 pounds, this screw is engineered for precision clamping of indexable carbide inserts. Licensed machinists, toolroom technicians, and CNC setup personnel install this hardware as part of routine insert indexing and replacement cycles on milling tools.\u003c\/p\u003e\n\u003cp\u003eThis lock screw is used in milling applications where indexable inserts must be firmly and repeatedly seated in the toolholder pocket. It is compatible with XO.. 1806 series inserts and is suited for production machining environments where consistent clamping torque and reliable insert retention are critical. The countersunk head profile keeps the screw flush with the toolholder body, minimizing interference with the cutting zone. It is sold individually but carries a minimum order quantity of 10 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTorx Plus TP20 drive resists cam-out and extends driver life during high-frequency insert changes\u003c\/li\u003e\n  \u003cli\u003eM4.5 thread size is standard for a wide range of indexable milling toolholders\u003c\/li\u003e\n  \u003cli\u003eCountersunk head profile sits flush to avoid interference with the cutting path\u003c\/li\u003e\n  \u003cli\u003eCompatible with XO.. 1806 indexable insert series\u003c\/li\u003e\n  \u003cli\u003eRequires T20P-3 key driver for proper installation\u003c\/li\u003e\n  \u003cli\u003e10 mm overall length suits standard toolholder pocket depth\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with XO.. 1806 series indexable inserts.

Before replacing the lock screw, ensure the machine spindle is fully stopped and the tool is removed from the machine or the machine is in a safe lockout state. Use only the specified T20P-3 Torx Plus driver to avoid stripping the drive recess. Do not use standard Torx drivers, as Torx Plus geometry differs and can damage the screw head.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: TP20\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: M4.5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 10 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKey\/Driver Compatibility\u003c\/strong\u003e: T20P-3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndexable Tool Type\u003c\/strong\u003e: Milling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: XO.. 1806\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  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\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: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 00040072\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51564072403250,"sku":"00040072","price":109.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4b32ab973d17d8bbdaf5b0457089f670_5f192fe6-1a10-4994-b2a4-136f72babbbb.jpg?v=1786510208","url":"https:\/\/voomisupply.com\/products\/seco-00040072-lock-screw-tp20-torx-plus-m4-5-milling","provider":"Voomi Supply","version":"1.0","type":"link"}
