Seco 02409608 Lock Screw TP20 M5 Milling Turning Insert

Product Description

The SECO 02409608 is a countersunk lock screw designed to secure indexable inserts in milling and turning toolholders. It features a Torx Plus TP20 drive and an M5 thread, delivering the precise clamping force needed to hold carbide inserts firmly during cutting operations. At 13.00 millimeters in overall length, the screw is sized for standard insert pockets that call for an M5 fastener. Toolroom technicians and machinists install this screw as a replacement or consumable component when lock screws become worn, stripped, or lost during routine insert changes.

This lock screw is suited for use in indexable milling and turning toolholders that accept an M5 countersunk lock screw with a TP20 Torx Plus drive. It is compatible with insert style C05013-T20P and is a practical stock item for shops running high-volume indexable tooling programs. Packaging quantity is one screw per package, with a minimum order quantity of ten units.

Installation Notes

Lock screw installation and replacement is performed by machinists or toolroom technicians during routine insert indexing or changeover. Always use a calibrated Torx Plus TP20 key to avoid rounding the drive recess. Do not use standard Torx keys in place of Torx Plus keys, as the drive geometry differs. Inspect the screw threads and pocket threads for wear or damage before reinstalling to prevent insert movement during cutting.
