Seco 02436169 M5 Lock Screw T20P Torx Plus Indexable Milling

Product Description

The SECO 02436169 is a countersunk lock screw designed to secure indexable inserts in milling toolholders. It uses a T20P Torx Plus drive and an M5 thread, providing precise torque engagement that minimizes cam-out and protects the insert pocket. The overall length is 18.00 mm. This screw is a direct replacement component used by machinists and toolroom technicians performing insert changes on indexable milling tools. Sold individually per package, with a minimum order quantity of 10 units.

This lock screw is intended for indexable milling applications where M5-threaded insert pockets are used. It fits toolholders that accept a T20P Torx Plus drive for insert clamping. Typical installation scenarios include production machining environments and job shops where inserts are rotated or replaced at regular intervals to maintain cutting performance. The countersunk head profile seats flush within the toolholder pocket, keeping the clamping geometry consistent across insert changes.

Compatibility

Designed for indexable milling toolholders requiring an M5-threaded, T20P Torx Plus drive lock screw for insert clamping. Compatible with insert-type indexable tooling as noted in the manufacturer catalog under reference number C05018-T20P.

Installation Notes

Installation is performed by machinists or toolroom technicians during scheduled insert changes or toolholder maintenance. Always ensure the toolholder is removed from the spindle and the machine is in a safe, powered-down state before servicing insert hardware. Use a calibrated T20P Torx Plus key and follow the toolholder manufacturer's recommended insert clamping torque procedure. Inspect the screw threads and pocket threads for wear or damage before reinstalling.
