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

Servo horn screw 2x4mm

This is a small-scale RC accessory intended for fastening servo horns on compatible Futaba servos. The set contains 10 pcs of 2x4mm screw fasteners designed to secure the horn to the servo output spline, keeping the horn stable under normal hobby use.

When replacing worn or lost hardware, match the 2x4mm size and thread form to the original screw to ensure correct fit. Use a suitable precision screwdriver, apply light controlled torque, and check for proper engagement with the horn and servo spline during reassembly to avoid stripping threads.

These screws play a simple but important role in setup and tuning: a properly tightened screw keeps horn play to a minimum, preserving servo centering and steering precision without affecting internal servo settings.
