Seco 02436148 Lock Screw Indexable TP8 Torx Plus M2.5

Product Description

The SECO 02436148 is a lock screw designed to secure indexable cutting inserts in toolholders used in CNC turning, milling, and boring applications. It features an M2.5 thread and a TP8 Torx Plus drive, which provides improved torque transfer and reduced risk of drive recess wear compared to standard Torx configurations. The countersunk head seats flush to keep the insert clamping pocket clear. At 5.20 millimeters in overall length, this screw is sized for compact insert pockets common in precision toolholding systems. Installation and replacement are performed by machinists and toolroom technicians as part of routine insert indexing maintenance.

This lock screw is used in metal cutting operations where indexable inserts are mounted in toolholders requiring an M2.5 thread pattern and a TP8 Torx Plus drive. It is compatible with insert style C02505-T08P. Typical applications include production turning, facing, and milling on CNC lathes and machining centers in both job shop and high-volume manufacturing environments. This screw is sold individually but must be ordered in multiples of 10.

Installation Notes

Installation is performed by machinists or toolroom technicians during insert indexing or replacement. Always ensure the spindle or machine is powered down and the toolholder is secured before removing or installing lock screws. Use a calibrated TP8 Torx Plus key to seat the screw properly and avoid over-torquing, which can damage the thread or drive recess. Inspect the screw for wear or thread damage at each insert change and replace as needed.
