OVERVIEW
Original combination hardware for the specified engine attachment
N-903-202-06 is a Genuine VW/Audi M10 x 35 bolt with an internal hex drive and a washer-style bearing arrangement. It is used at specific original engine mounting and support locations in the applications listed below.
The engine-support and transmission configuration determines the correct fastening point. Several neighboring bolts can share similar dimensions, so the full factory number, engine branch and original hardware arrangement must be checked.
Technical details
- Complete factory number: N-903-202-06.
- Factory specification: M10 x 35 mm internal-hex combination bolt.
- Design: Cylindrical socket head with washer-style bearing arrangement and threaded shank.
- Quantity supplied: one individual bolt; engine support, hydraulic mount, bracket and other attachment pieces are not included.
M10 x 35 describes nominal thread diameter and fastener length. No unverified thread pitch, strength class, tightening torque, weight or shipping dimensions are supplied.
Common reasons to replace
- A rounded internal drive that no longer permits controlled tightening.
- Damaged threads, a bent shank or a damaged bearing arrangement.
- Missing hardware or an incorrectly substituted fastener discovered during support or mounting service.
Engine movement or vibration can also come from a worn hydraulic mount, damaged bracket or another support fault. Inspect and diagnose the complete mounting system; this bolt does not replace the mount itself.
