Seco 02434334 Indexable Lock Screw M3 TP9 Torx Plus

Product Description

The SECO 02434334 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 positive engagement and consistent clamp force during cutting operations. At 6.30 millimeters in overall length, the screw is sized for compact insert pockets commonly found in milling applications. This part is sold individually but must be ordered in multiples of 10. Installation and replacement are typically performed by machinists and toolroom technicians maintaining indexable cutting tool assemblies.

This lock screw is intended for use in indexable milling toolholders that accept M3 threaded insert clamping hardware. It is compatible with C03006-T09P insert style configurations. The TP9 Torx Plus drive reduces cam-out risk compared to standard Torx or hex drives, making it well suited for high-frequency insert changes in production environments. Both manual and torque-wrench-assisted installation are common in shop settings where repeatable clamp force is required.

Compatibility

Compatible with indexable milling toolholders requiring M3 thread lock screws with a TP9 Torx Plus drive and countersunk head. Designed for use with C03006-T09P insert style configurations.

Installation Notes

Installation is typically performed by a machinist or toolroom technician. Power down and lock out the machine before changing inserts or lock screws. Use a calibrated torque wrench with a TP9 Torx Plus bit to achieve consistent clamp force and avoid overtightening, which can strip the M3 thread or crack the insert. Inspect the screw threads and pocket threads for wear or contamination before reinstallation.
