Futaba FUJ55171 Servo Horn Screw 2.6x6mm 10pcs for S3115/S3116  [FUJ55171]

Servo horn screw for S3115/S3116

This Futaba FUJ55171 item is a pack of 10 small screws intended for RC servo horn mounting on Futaba S3115 and S3116 scale servos. Each screw is specified as 2.6x6mm in length and diameter, and the set is supplied without retail packing. The parts are designed as direct replacement fasteners for the servo horn and related linkage mounting points on model servos.

Installation is straightforward: use the matching pilot holes on the servo horn, thread each 2.6x6mm screw carefully to avoid cross-threading, and tighten to a firm but not over-torqued setting to protect plastic or composite horns. For metal horns use slightly firmer torque, for plastic horns leave minimal preload to avoid stripping. These screws serve a basic but important role in keeping horn-to-servo connections secure and repeatable during setup and tuning.

When tuning servo throw or swapping horns, keep extra screws on hand to avoid losing small hardware at the track or bench. Because the pack is small and low-cost it’s practical to carry a spare set for routine maintenance and quick repairs.
