Abstract
An electrically isolated coupler includes a drive body, a driven body, and a torque transfer assembly. The drive body is made of first metallic material and has a drive end configured to interface with a fastening component. The drive body includes a first interface portion and the driven body includes a second interface portion. The driven body is made of a second metallic material and has a driven end configured to interface with a driving tool. The torque transfer assembly is disposed between the drive body and the driven body to electrically isolate the drive body and the driven body from each other and transfer torque between the drive body and the driven body. The torque transfer assembly includes non-conductive material configured to maintain separation between the drive body and the driven body of at least about 0.400″.
