The Combo Pack 6x HS-485HB with 6 Free Metal Servo Horns includes six 485HB servos and six metal servo horns. Together, they produce one of the most durable and reliable servos ever offered. With a top ball bearing, heavy duty, high impact Karbonite gears and high performance circuitry, the 485HB offers lots of torque and features excellent centering and resolution. It includes tapped metal servo horns.
The Lynxmotion metal servo horn replaces the plastic servo horn included with the 485 servo, making it far more durable. The pattern is compatible with the Lynxmotion servo erector set and uses 2-56 screws.
