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

Product summary for servo horn screws

This Futaba FUEBS0412 pack provides ten 3x8mm screws as replacement hardware for fitting servo horns to Futaba servos S9150, S9154, BLS154 and BLS174. The screws are sold loose without retail packaging.

Use case: intended as straightforward replacement fasteners to secure the horn to the servo output spline, these screws are ideal for repairs at the track or workshop when originals are lost or damaged. They are for model equipment only.

Installation notes: verify the 3x8mm size suits your horn and spline clearance before final tightening. Begin threading by hand, avoid over-tightening which can strip plastic horns or deform servo cases, and confirm full-range horn movement after installation.

Maintenance and tuning role: store a spare pack in your toolkit to quickly recover from linkage failures; inspect screws after high-stress runs and re-tighten as needed to maintain reliable control response.
