Futaba FUEBS0412 3x8mm Servo Horn Screws (10pcs) for S9150 S9154 BLS154 BLS174  [FUEBS0412]

Servo horn screw details

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 act as basic fastening hardware for attaching the servo horn to the servo output spline and are suited to 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 by hand first and avoid over-tightening to prevent stripping the horn or servo case; verify horn movement is smooth across its travel after fitting.

Maintenance and tuning role: keep a spare set in your parts kit to restore linkage integrity quickly during practice runs or events, and periodically check screws for looseness after break-in and heavy-load use.
