About universal joints

1/4 in. x 3/8 in. x 1/2 in. Drive U-Joint Set (3-Piece) is listed under Universal Joints — single and double u-joints, drive shafts and telescoping joints. Universal joints, also known as Cardan joints or universal couplings, transmit rotary motion and torque between shafts that are not collinear. They accommodate angular misalignment, and some designs also manage axial displacement.
