Used to strengthen the splines on the pictured horn.

Without confirming ID a bit confused. Does that encircle the bottom of the horn to prevent the splines from spreading under load?

Personally, if I though that was the case would go with an alloy arm.

Yes. And your thinking is also correct, however certain applications the servo is used in mandate a heavier duty plastic arm. Or some may opt to use the plastic arm for cost savings sake.
