Walter 5516956 Indexable Insert Clamping Screw

Product Description

The WALTER 5516956 is a clamping screw designed for indexable insert toolholders, used to secure carbide or cermet inserts in place during turning, milling, or boring operations. The Torx Plus drive head provides a higher torque transfer compared to standard hex or Torx designs, reducing the risk of cam-out and fastener damage during insert changes. This screw is a direct-fit replacement hardware component intended for use by machinists, toolroom technicians, and CNC setup personnel who service indexable tooling assemblies.

Indexable insert clamping screws are consumed parts that require periodic replacement due to drive-head wear, thread damage, or loss during insert indexing. This screw suits toolholders that accept the FS2110 industry-standard clamping screw specification. It is appropriate for both production machining environments and job-shop toolrooms where indexable tooling systems are maintained in-house.

Key Features

• Torx Plus drive for improved torque engagement and reduced cam-out risk
• Conforms to industry standard number FS2110
• Direct replacement for worn or damaged indexable toolholder clamping screws
• Lightweight at 0.01 pounds, suitable for high-volume stocking
• Sold individually, allowing single-piece replacement without excess hardware

Compatibility

Designed to fit indexable toolholders requiring the FS2110 industry-standard clamping screw specification. Verify your toolholder documentation or existing screw markings confirm FS2110 fitment before installation.

Installation Notes

Installation should be performed by qualified machinists or toolroom technicians familiar with indexable tooling systems. Remove all cutting load from the toolholder and ensure the spindle or machine is fully powered down and locked out before replacing clamping screws. Use a calibrated Torx Plus driver of the correct size to avoid drive-head damage. Do not exceed the torque specification listed in the toolholder manufacturer documentation for this screw size.
