This Futaba FUJ55204 kit contains ten 2.6x10mm screws supplied for fitting to Futaba servo horns. These fasteners serve as direct replacement items for the referenced model codes and are intended to clamp the horn securely to the servo output spline to preserve reliable mechanical linkage during model operation.
Compatibility: the listing cites Futaba S9151, S9252, S9254 and S9257 as related servo models; confirm that the 2.6x10mm length and thread match your horn and servo before installing. Their compact dimensions make the screws convenient spares for field repairs and routine maintenance.
Installation and setup note: the screws secure the horn to the output shaft, so ensure correct seating and full thread engagement to prevent linkage play. When adjusting steering or control response, include these fasteners in your checks and replace any stripped or lost screws from this pack to maintain consistent control feel.
