OVERVIEW
Factory double-collared stud for the fender mounting assembly
N-912-440-01 is the Genuine VW/Audi double collared stud used at the assigned fender and end-cover mounting positions on the confirmed Audi A4 applications below.
The two threaded portions and central hexagon provide the original mounting arrangement. This small service fastener is supplied separately from the fender, end plate, cover and supporting brackets.
Technical details
- Complete factory number: N-912-440-01.
- Factory specification: M6 x 22 factory designation.
- Design: double collared threaded mounting stud with central hexagon.
- Quantity supplied: one individual stud.
M6 is the nominal thread size and 22 mm is the catalog dimension for this stud. Match the complete factory number and exact mounting position rather than substituting a general-purpose bolt.
Common reasons to replace
- The stud is missing after body or trim service.
- Threads are damaged or crossed.
- The central hexagon is rounded or damaged.
- The stud is bent and no longer aligns the original connection.
- The bearing collars are damaged or cannot seat correctly.
Inspect the mating receiver, bracket, cover and mounting faces. A new stud cannot repair a cracked mount or distorted body component. Correct alignment before tightening the connection.
