Seco 02440263 Lock Screw TP15 Torx Plus M4 Thread Milling

Product Description

The SECO 02440263 is a countersunk lock screw designed to secure indexable inserts in milling toolholders. It uses a Torx Plus TP15 drive and an M4 thread, and it is compatible with the T15P-3 key driver. The countersunk head profile seats flush against the insert pocket, keeping the cutting insert firmly positioned during milling operations. This type of fastener is a standard consumable in indexable tooling systems and is replaced as part of routine toolholder maintenance by machinists and toolroom technicians.

This lock screw is intended for use in indexable milling applications where M4 thread insert pockets are specified. It is compatible with insert style C94005-T15P and fits toolholders requiring a TP15 Torx Plus drive interface. The T15P-3 key driver is required for installation and removal. This screw is typically used in production machining environments, job shops, and maintenance toolrooms where indexable milling toolholders see regular insert changes.

Compatibility

Compatible with indexable milling toolholders requiring an M4 thread lock screw with TP15 Torx Plus drive. Insert style compatibility includes C94005-T15P. The T15P-3 key driver is required. Partial insert compatibility also noted for 1204-series inserts per supplier data. Verify thread size and drive type against your specific toolholder specification before ordering.

Installation Notes

Installation and removal should be performed by a qualified machinist or toolroom technician using the specified T15P-3 Torx Plus key driver. Always de-energize and lock out the machine before changing inserts or servicing toolholders. Do not use standard Torx drivers in place of the Torx Plus driver, as this can damage the screw head. Inspect the lock screw and insert pocket threads for wear or contamination at each insert change interval.
