If you bought a servo from us you probably got a bunch of plastic add-ons that you can snap onto the rotating part of the servo. These are called 'servo horns' and the standard ones you'll get are plastic pieces. They're good but often short and not very strong plastic.

This Machined Aluminum Servo Arm lets you bring your A-Game to servo projects. It's strong anodized aluminum. Looks great, is easy to install, and will last for a long time.

The servo arm is 37mm long and the arm part is 2.5mm thick aluminum. It has four tapped 2.5mm screw holes and a 3mm screw hole on the end (M3 compatible). The holes are 15mm, 20mm, 25mm, and 30mm from the center rotational point. 

The center part mates with 25-tooth servo axles. We've found it's compatible with our standard-size servo motors:

But it will not fit neither the Parallax Feedback 360 Degree High Speed Continuous Rotation Servo nor micro and sub-micro servos.
