Futaba FUEBS0412 Servo Horn Screw Pack 10x 3x8mm Compatible with S9150 S9154 BLS154 BLS174  [FUEBS0412]

Details and guidance for these screws

This Futaba FUEBS0412 listing describes a pack of ten 3x8mm screws supplied as replacement fasteners for securing servo horns on Futaba servo models S9150, S9154, BLS154 and BLS174. The screws are supplied without retail packaging.

Use case: intended as replacement hardware to attach the servo horn to the output spline, these screws are useful for routine servicing and on-track fixes where original screws are lost or damaged. They are designed solely for model use.

Installation notes: prior to tightening confirm that the 3x8mm screw length and thread type match your horn and spline clearance. Start screws by hand, avoid over-tightening to prevent stripping, and check the horn runs smoothly through its full travel once fitted.

Maintenance and tuning role: keep a set of these screws in your spares box to minimise downtime; inspect and re-tighten after aggressive sessions and replace any screws that show wear or deformation.
