OVERVIEW
Original M6x20 combination fastener for the specified joint
N-103-471-03 is the Genuine VW/Audi M6x20 combination bolt used at the specified original mounting positions. The rounded head has an internal six-lobe drive and a captive washer that distributes the clamp load across the assigned component.
Correct fastener length, head form and washer arrangement help the original joint clamp as intended. This bolt is used in several different assemblies; the correct replacement depends on the specific cataloged mounting point.
