This is a ProTek R/C 4mm Aluminum Long Clamp Lock Servo Horn, and is intended for use with any servo that uses a 24 tooth spline output shaft. This extremely tough servo-horn has been machined from a solid block of aluminum for incredible precision, rigidity and durability. This horn features a clamp type design that grips the servo’s output shaft with enough force that even if the retainer screw comes loose, the horn will remain in place, increasing your chances of finishing the race! Additionally, the arm is 4mm thick for durability, has 19.75mm & 24.25mm hole spacing and uses 3mm hardware to suit the geometry and hardware requirements of most vehicles.

ProTek RC 4mm Aluminum Long Clamping Servo Horn (Blue) (24T-Hitec)
I bought one of these to test on my XR10 (crawler). It works very well, though a bit longer than necessary for my setup.

But wanted to comment that this is very well-machined. It's definitely very beefy. I would imagine that to bend this horn, you'd have to hit it hard enough to destroy your servo, but I'm not going to test that. But all of it is machined perfectly. Slips right onto the HiTec servo without any strong effort and it bites exceedingly well once all three screws are tightened.

Amain won me over with their store brand quite a while back because every Pro-Tek branded item I've purchased has exceeded my expectations and has been superb quality in every regard.
