Durable 2x4mm horn fasteners

These small-scale RC screws are made for securing servo horns on Futaba servos. The kit contains ten 2x4mm screws sized to hold the horn to the servo output spline for consistent performance during normal hobby use.

Replace worn or missing screws by matching the 2x4mm measurement and the thread profile to the originals. Use an appropriate precision screwdriver, apply modest torque, and ensure full engagement to avoid stripping the assembly.

Properly installed screws reduce horn slack, helping the servo maintain neutral centering and accurate steering without changing internal settings.

How tough are these screws for regular use?

Designed for hobby applications, these screws are suitable for normal use. For heavy duty or competitive running inspect for wear more often and replace at the first sign of thread damage.

Can I reuse the original screws or should I replace them?

If originals are undamaged you can reuse them, but if heads are rounded or threads show wear, swap to these 2x4mm replacements to ensure secure horn mounting.
