Create A New AccountThe Proto 3/8-Inch Drive Impact Universal Joint is engineered to withstand the high torque and repetitive stress of powered impact tools. Tight tolerances ensure a snug fit on fasteners, while the ball and spring design allows up to a 30° working angle and smooth 360° rotation — ideal for reaching fasteners where obstructions prevent a straight-line application.
Features two through holes and a groove compatible with a Proto Retaining Ring or pin and O-ring to securely retain the socket to the drive tool anvil. A dependable solution for installation and removal tasks in industrial, MRO, and professional automotive applications.
