Product summary: servo horn screws

This Futaba FUEBS0412 is offered as a pack of ten 3x8mm screws meant to replace or renew the fasteners that hold servo horns to the output splines of Futaba servos S9150, S9154, BLS154 and BLS174. The screws come without retail packaging.

Use case: designed to serve as replacement hardware for securing servo horns during assembly or when performing trackside repairs. They are intended for model use and are not suitable for full-size applications.

Installation notes: ensure the 3x8mm length and thread form are compatible with your horn and spline before tightening. Always hand-start threads, tighten progressively and avoid excessive torque to prevent damaging plastic horns or the servo case; check horn travel after fitting.

Maintenance and tuning role: keep these screws as part of your basic spares to reduce downtime during events; check for loosening after hard impacts or aggressive maneuvers and re-tighten as necessary.
