Product Description
The SECO 02794268 is a machine screw designed for securing indexable cutting inserts in compatible toolholders and boring bars. It features an M3.5 thread with a T10P Torx drive and a countersunk head profile, allowing flush seating against the insert pocket. This screw is a precision fastener used in CNC turning, milling, and boring applications where insert retention and seating accuracy are critical. Machinists and toolroom technicians use this type of screw as a direct replacement when original screws are lost, damaged, or stripped during insert changes.
This screw is suited for use in production machining environments where indexable insert tooling is regularly serviced. It is a single-piece replacement fastener intended for toolholders that accept M3.5 insert clamping screws with a T10P Torx drive. The countersunk head geometry ensures the screw sits flush within the insert pocket, maintaining proper insert orientation and clamping force. It is sold individually, making it practical for replacing a single worn or damaged fastener without ordering in bulk.
Key Features
- M3.5 thread size for compatibility with standard indexable insert pockets requiring this thread specification
- T10P Torx drive reduces cam-out risk during tightening compared to hex socket drives
- Countersunk head profile seats flush with the insert pocket surface
- Overall length of 7.70 mm suits shallow insert clamping configurations
- Lightweight construction at 0.05 pounds for easy handling and inventory
- Sold as a single unit, allowing targeted replacement without excess inventory
Compatibility
Designed as an OEM-style replacement machine screw for indexable insert toolholders that require an M3.5 thread and T10P Torx drive clamping screw with a countersunk head.
Installation Notes
Installation is performed by qualified machinists or toolroom technicians during insert indexing or replacement. Always power down and lock out the machine before accessing the toolholder. Use a calibrated T10P Torx driver or key and follow the toolholder manufacturer’s recommended torque specification for M3.5 insert screws. Do not overtighten, as this can strip the thread or crack the insert.
