Seco 02602670 Lock Screw Torx Plus M3 Thread Milling

Product Description

The SECO 02602670 is a countersunk-head lock screw designed to secure indexable inserts in milling toolholders. It uses a Torx Plus T09P drive and an M3 thread, providing reliable clamping force to hold replaceable cutting inserts firmly in position during machining operations. With an overall length of 7.20 millimeters and a weight of 0.01 pounds, this screw is a compact, precision-fit fastener. It is installed and replaced by machinists, tool crib technicians, and CNC setup personnel as part of routine insert indexing and toolholder maintenance.

This lock screw is intended for use in milling applications where indexable insert toolholders require a secure, repeatable clamping method. It is suited to production and job-shop environments running milling operations that demand frequent insert changes. The Torx Plus drive reduces cam-out risk during tightening and removal, making it well suited to high-cycle insert indexing workflows. The minimum order quantity for this screw is 10 units, and each package contains 1 unit, so order planning should account for those multiples.

Installation Notes

Installation and replacement should be performed by qualified machinists or toolroom technicians familiar with indexable toolholder systems. Always ensure the spindle is stopped and the machine is in a safe, locked-out state before accessing the toolholder. Use the correct T09P Torx Plus driver to avoid drive recess damage. Do not use standard Torx drivers in place of Torx Plus drivers, as the drive geometries differ and can cause recess damage or improper seating.
