N-011-008-40 Genuine VW/Audi M8 Hex Nut

Genuine VW/Audi M8 hex nut, part number N-011-008-40. This small mounting fastener secures the assigned component to its matching stud or bolt. Its hex exterior provides a tool engagement surface, while its flat bearing face bears against the mounting face.

Technical details

• Original part number: N-011-008-40 / N01100840.
• M8 nominal thread size; standard hex nut.
• Six-sided nut with internal threads, as shown in the original photo.
• Supplied individually. Mating bolts, studs, brackets and other components are separate.
• Used at multiple factory mounting locations, including the specific assemblies listed below.
• Thread size alone does not establish equivalence. Match the original part assignment and bearing-face arrangement.

Common reasons to replace

Replace a missing nut, one with stripped or corroded threads, or a nut whose hex faces are too damaged for reliable tool engagement. A damaged bearing face or damaged mating surface can prevent proper seating even when the nut still threads onto the stud.

Loose mounting hardware or movement at the supported component warrants inspection of the full connection. Check the stud or bolt, bracket, mounting surface and any required spacers. Replacing the nut will not correct a broken stud, cracked bracket or worn mounting point.

Installation and service notes

Support the component before loosening its hardware. Check that the replacement matches the original nut and thread it on by hand. Do not force it onto damaged or mismatched threads.

Seat the nut against the intended mounting face and tighten to the specification for that exact assembly. Follow any factory replacement requirement for the adjoining hardware. Recheck that the component is secure and that wiring, hoses or moving mechanisms remain correctly positioned.

Fitment

Confirm the factory fastener assignment at the intended mounting location before ordering.
