Seco 02496697 Lock Screw Indexable TP9 Torx Plus M3

Product Description

The SECO 02496697 is a countersunk lock screw designed to secure indexable inserts in milling toolholders. It features an M3 thread and a TP9 Torx Plus drive, providing a positive, torque-efficient engagement that resists cam-out during tightening. The countersunk head profile seats flush against the insert pocket, maintaining proper insert seating and preventing interference with the cutting path. At 8.40 millimeters overall length, the fastener is sized for compact insert pockets typical in modern milling cutter bodies. This screw is part of the QuattroMill series and is intended for use by machinists and toolroom technicians maintaining CNC or manual milling setups.

This lock screw is used in milling operations where indexable carbide or cermet inserts must be clamped securely in the insert pocket of a milling cutter body. It is suited to high-feed and face milling applications where insert retention under interrupted cutting loads is critical. The QuattroMill series designation indicates compatibility within that SECO tooling platform. Minimum order quantity is 10 pieces, sold in individual unit packaging.

Compatibility

Designed for use with indexable milling inserts in the SECO QuattroMill series toolholders requiring an M3 thread lock screw with a TP9 Torx Plus drive.

Installation Notes

Installation is performed by toolroom technicians or machinists during insert indexing or replacement. Always use a calibrated TP9 Torx Plus key and follow the toolholder manufacturer's specified tightening procedure — do not substitute a standard Torx driver, as Torx Plus flanks have a different profile. Ensure the insert pocket and screw threads are clean and free of chips before seating the screw. Replace lock screws that show thread wear or head deformation to maintain reliable insert clamping.
