Futaba FUB00104 2x4mm Servo Horn Screw Pack 10pcs  [FUB00104]

Replacement servo horn screws 2x4mm

This small RC accessory is intended for fastening servo horns for Futaba servos. The pack includes 10 pieces of 2x4mm screws designed to clamp the horn onto the servo output spline for stable hobby use.

When swapping out old or missing hardware, confirm the 2x4mm dimension and thread profile match the original. Use a precision screwdriver, apply light torque, and check the screw engages fully to avoid stripping the horn or servo threads.

Correct screw tension reduces horn play, helping preserve servo centering and steering accuracy during setup and tuning without altering internal servo settings.
