OVERVIEW
Genuine VW/Audi Hexagon Nut M10
N-102-613-04 is an original M10 hexagon nut used at specified engine-to-transmission fastening points. The documented Passat applications below identify the gearbox configurations and catalog positions that call for this exact hardware. Its hexagon allows engagement with the correct wrench or socket, and its integral collar provides the assigned seating surface. One individual nut is supplied.
Technical details
- OEM number: N-102-613-04 / N10261304.
- Catalog identity: Hexagon nut; also described as a shouldered nut.
- Nominal thread size: M10, as confirmed by the original manufacturer parts listing.
- Construction visible in the archive: Hexagon body with an integral collar and internal threads.
- Documented function: Retention at assigned engine and transmission mounting-hardware positions.
- Supply: One nut. Matching bolts, sleeves, brackets and remaining transmission fasteners are separate components.
Common reasons to replace
Replace this nut when its threads are damaged or corroded, the hexagon has been rounded, or the collar and seating area no longer sit correctly against the assigned mounting surface. Missing hardware or an incorrect substitute should also be corrected when assembling the engine and transmission. A worn tool or partial tool engagement can damage the hexagon, making accurate tightening and future removal more difficult.
Inspect the mating bolt or stud and the receiving assembly before installing a new nut. Damaged threads, an incorrect bolt length or a distorted seating surface will not be corrected simply by replacing the nut. A loose engine-to-transmission fastening point calls for checking the complete joint, alignment sleeves and specified hardware. Transmission noise or a starting problem alone does not establish that this particular nut requires replacement.
Installation and service notes
Match the complete OEM number, installed gearbox code and original fastening position before ordering. The original transmission catalog uses different hardware at adjacent positions, and identical nominal thread sizes do not establish interchangeability. Keep the fastening hardware organized by its original position during disassembly, especially where several bolt lengths and seating arrangements are present.
Support and align the engine and transmission according to the applicable service procedure. Inspect the mating threads and seating surfaces, start the nut by hand, and use a tool that fully engages the hexagon. Do not draw misaligned components together by forcing the fasteners. Follow the original tightening sequence, torque and any hardware-renewal requirement for the exact installation. Check the remaining mounting hardware separately before restoring operation.
Vehicle fitment
