Seco 02860113 Machine Screw M4 T15P Hex Milling Insert

Product Description

The SECO 02860113 is a machine screw designed to secure indexable inserts in milling toolholders. This small-format fastener uses an M4 thread and a T15P Torx Plus hex drive, providing the precise clamping torque needed to hold cutting inserts firmly in place during machining operations. The overall length is 5.60 millimeters, making it well-suited for compact indexable tooling systems. It is typically installed and replaced by machinists, toolroom technicians, and CNC setup personnel who maintain indexable tooling on milling machines and machining centers.

This screw is intended for indexable milling applications where insert retention hardware must be replaced due to wear, stripping, or loss during insert changes. Indexable insert screws are consumable components in high-use tooling environments and are routinely stocked in toolrooms and on service carts. The M4 thread size and T15P drive format are common hardware specifications across a range of indexable milling toolholders that use this fastener style for insert clamping.

Key Features

• M4 thread size for precise, controlled clamping of indexable inserts
• T15P Torx Plus hex drive for secure torque application with reduced cam-out risk
• 5.60 mm overall length suited for compact indexable milling toolholder pockets
• Designed for milling insert hardware compatibility
• Sold individually, allowing single-unit replacement without excess inventory

Compatibility

Designed as an OEM-style replacement machine screw for indexable milling toolholders requiring an M4 thread, T15P Torx Plus hex drive insert retention fastener.

Installation Notes

Installation is performed by machinists or tooling technicians during insert indexing or replacement. Always use the correct T15P Torx Plus key to apply the manufacturer-recommended torque and avoid stripping the drive socket. Ensure the toolholder pocket and thread bore are clean and free of chips before seating the screw. Never reuse a screw that shows signs of thread damage or deformation.
