Seco 02440264 Lock Screw TP15 Torx Plus M4 Milling

Product Description

The SECO 02440264 is a countersunk lock screw designed to secure indexable inserts in milling toolholders. It uses a Torx Plus TP15 drive and an M4 thread to clamp inserts firmly during cutting operations. The countersunk head profile seats flush with the toolholder pocket, keeping the clamping hardware clear of the workpiece. At 6.20 mm overall length, this screw is sized for compact indexable toolholder assemblies used in production and job-shop milling. Installation requires the T15P-3 key driver. This hardware is installed by machinists and CNC toolroom technicians performing insert changes or toolholder maintenance.

The 02440264 is intended for use in milling applications with toolholders that follow the 335.19 style specification. It is compatible with C94006-T15P insert style and SNHQ 12045 series indexable inserts. This screw is sold individually but must be ordered in multiples of 10. It is suited for production environments where insert changes are frequent and consistent clamping torque is critical to tool life and surface finish quality.

Installation Notes

Lock screws should be installed by qualified machinists or toolroom technicians familiar with indexable tooling systems. Power down and lock out any machine spindle before performing insert changes or screw replacement. Always use the specified T15P-3 Torx Plus driver to avoid rounding the drive recess. Inspect the thread in the toolholder pocket for damage before installing a replacement screw.
