Seco 02436160 Lock Screw TP15 Torx Plus M3.5 Thread Milling

Product Description

The SECO 02436160 is a countersunk lock screw designed to secure indexable inserts in milling toolholders. It features a Torx Plus TP15 drive and M3.5 thread, providing the precise clamping force needed to hold carbide inserts firmly during milling operations. The countersunk head profile seats flush against the insert, minimizing interference with the cutting zone. Installation requires a T15P-3 key driver. This screw is intended for use in R33.15-style toolholders and is a direct OEM-style replacement for worn or damaged clamping hardware on indexable milling systems. Machinists and toolroom technicians install this component as part of routine insert changes or toolholder maintenance.

This lock screw is used in indexable milling applications where insert retention hardware must be replaced to maintain clamping integrity. It is compatible with R33.15 toolholders and fits a range of R335.15 series indexable inserts. Typical install scenarios include production milling environments where insert changes are frequent and reliable clamping hardware is critical to consistent cutting performance and insert seating accuracy.

Installation Notes

Installation is performed by machinists or toolroom technicians during routine insert changes or toolholder service. Power down and lock out any machine spindle before accessing the toolholder. Use only the specified T15P-3 Torx Plus driver to avoid stripping the drive recess. Inspect the thread bore in the toolholder for contamination or damage before threading in the replacement screw.
