Precision 2x4mm horn screws for stable steering

This accessory set provides ten 2x4mm screws intended to secure servo horns on Futaba servos. They fasten the horn to the servo output spline to maintain stable control during ordinary RC use.

When changing screws, verify the 2x4mm size and thread form match the originals. Use a small precision driver, tighten gently, and check the horn-to-spline engagement to prevent stripping threads during reassembly.

Good installation practice keeps horn play minimal, which helps preserve servo centering and steering precision during setup, tuning and everyday use.

Do these screws affect servo tuning or travel?

The screws themselves do not change internal tuning, but a secure horn mount reduces play so the servo's set centering and travel are accurately translated to the steering linkages.

What torque should I use during installation?

Apply light, controlled torque. Tighten until the horn is snug with no wobble but stop if you feel excessive resistance, then back off slightly to prevent thread damage.
