Seco 02510358 Insert Lock Screw M2.5 T08P Torx Plus

Product Description

The SECO 02510358 is a countersunk lock screw designed to secure indexable inserts in milling toolholders. With an M2.5 thread size and a T08P Torx Plus drive, this screw provides reliable clamping force and positive engagement when seating carbide or cermet inserts in compatible milling bodies. The Torx Plus drive geometry reduces cam-out risk during tightening, which matters in high-cycle insert change environments. Overall length is 5.50 mm. This part is sold individually and is subject to a minimum order quantity of 10 units. Toolroom technicians, CNC machinists, and shop maintenance personnel are the typical end users.

This lock screw is used in milling applications where indexable inserts must be precisely and securely clamped. It is suited for face mills, shoulder mills, and other milling cutter bodies that accept M2.5 countersunk lock screws with a T08P Torx Plus drive. It is a direct replacement or replenishment screw for worn, stripped, or lost hardware in indexable milling systems. SECO catalogs this part under catalog number C02555-T08P.

Compatibility

Designed as a replacement lock screw for indexable milling toolholders that use M2.5 thread, countersunk, T08P Torx Plus drive insert clamping screws. Referenced under SECO catalog number C02555-T08P.

Installation Notes

Installation is performed by machinists or toolroom technicians during insert indexing or replacement. Use a calibrated T08P Torx Plus key and follow the toolholder manufacturer's recommended seating procedure. Do not overtighten, as M2.5 screws are subject to shear if torque is excessive. Inspect the screw threads and pocket threads for damage before each insert change.
