Futaba FUEBS0412 Servo Horn Screw 3x8mm 10pcs for S9150 S9154 BLS154 BLS174  [FUEBS0412]

Servo horn screw overview

This Futaba FUEBS0412 listing is an RC-scale replacement pack of 10pcs 3x8mm screws intended for securing servo horns on compatible Futaba servo models S9150, S9154, BLS154 and BLS174. The item is offered without retail packing as indicated.

Use case: these screws serve as basic hardware for attaching the servo horn to the servo output spline and for field repairs where original fasteners are missing or stripped. They are intended for model use only and not for full-size applications.

Installation notes: confirm the screw length and diameter match your servo horn and spline clearance before tightening. Engage threads fully but avoid over-tightening to prevent stripping the horn or servo case; check alignment after installation and verify horn movement is smooth across its travel.

Maintenance and tuning role: keep a spare set in your parts kit to restore mechanical linkage integrity quickly during practice sessions or events, and inspect screws periodically for loosening after run-in and high-load maneuvers.
