Walter 5589821 Torx Plus Drive Screw Indexable

Product Description

The WALTER 5589821 is a Torx Plus drive screw designed for securing indexable inserts in cutting tool holders. This small but critical fastener keeps indexable carbide inserts locked firmly in place during machining operations, preventing movement under cutting loads. The Torx Plus drive format provides better torque transfer and reduced cam-out compared to standard Torx configurations, making insert changes faster and more reliable. Installed by machinists and tooling technicians in production and job-shop environments, this screw is a direct consumable in any indexable tooling program.

This screw is used wherever indexable insert tooling is in service - turning, milling, boring, and grooving applications across CNC and manual machine setups. When an insert is rotated to a fresh edge or replaced entirely, the clamping screw is the first point of contact. Having the correct replacement screw on hand minimizes downtime during insert changes. The industry standard number FS2119 and catalog number FS2119 are associated with this part, which can aid cross-referencing in tooling management systems.

Key Features

• Torx Plus drive design reduces cam-out during tightening and loosening
• Industry standard number FS2119 for straightforward cross-referencing
• Lightweight at 0.01 pounds - minimal inventory footprint for a consumable item
• Single-piece packaging supports exact quantity ordering with no minimum beyond one unit
• Compatible with indexable tooling holders requiring FS2119-spec clamping screws

Compatibility

Designed for use with indexable insert tooling holders that accept an FS2119-specification Torx Plus drive clamping screw. Confirm the holder manufacturer's screw specification before ordering to ensure correct thread size and head geometry.

Installation Notes

Installation is performed by a machinist or tooling technician. Before changing an indexable insert, ensure the machine is powered down and the spindle is locked or the turret is in a safe index position. Use the correct Torx Plus key or driver to the tool manufacturer's recommended torque specification for the holder - do not substitute a standard Torx driver, as it may damage the drive recess. Inspect the screw threads and the holder pocket threads for damage at each insert change and replace the screw if wear is present.
