Abstract
An electrically isolated coupler includes a drive body, a driven body, an insulating member and an isolation coating. 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 insulating member is molded to fit between the drive body and the driven body to electrically isolate the drive body and the driven body from each other. The isolation coating is disposed on a surface of the first interface portion or the second interface portion that contacts the insulating member and faces the second interface portion or the first interface portion, respectively. The isolation coating includes a material that adheres to metal and has a dielectric strength of greater than about 10 kV.
