Seco 02440224 Indexable Insert Cap Screw T15 M3.5

Product Description

The SECO 02440224 is a countersunk cap screw designed to secure indexable inserts in turning toolholders. It features a T15 Torx Plus drive and an M3.5 thread, providing reliable clamping force with a proper torx-plus bit during insert changes. The countersunk head sits flush with the insert seat, preventing interference with the cutting zone. At 10.40 mm in overall length, this screw is sized for standard insert pocket geometry used in turning applications. Licensed machinists, toolroom technicians, and CNC setup personnel typically stock these screws as consumable hardware alongside their insert inventory.

This cap screw is used in indexable turning toolholders that accept M3.5 insert-mounting screws with a T15 Torx Plus drive. It is suited for production turning, general-purpose lathe work, and toolroom applications where inserts are regularly indexed or replaced. The countersunk head profile is compatible with insert styles that require a flush-seating fastener. The insert style designation C03510-T15P identifies the specific seat and drive geometry this screw is engineered to fit.

Installation Notes

Insert installation should be performed with the machine powered down and spindle locked. Use a calibrated T15 Torx Plus bit or key to tighten the screw; avoid standard Torx drivers, which do not fully engage the Torx Plus lobe geometry and can damage the drive recess. Do not exceed the toolholder manufacturer's specified tightening torque for M3.5 insert screws. Inspect the screw threads and drive recess for wear or damage each time inserts are indexed, and replace the screw if deformation is observed.
