N-015-083-15 Genuine VW/Audi M8 Shouldered Hex Nut

Genuine VW/Audi M8 shouldered hex nut, part number N-015-083-15. This original nut combines an external hexagonal drive with a broad integral collar. In the listed wiper applications it retains the arm at its assigned spindle mounting point, supporting the clamped joint between the arm and motor shaft.

Technical details

• Original part number: N-015-083-15 / N01508315.
• Nominal thread designation: M8.
• Hexagonal nut with an integrated collar; supplied individually.
• The same standard hardware number has multiple factory applications. The fitment table below identifies confirmed wiper applications rather than every M8 joint on each vehicle.
• Wiper arms, motors, protective caps and washers are not included.

Common reasons to replace

Replacement may be needed when the original nut is missing, its threads are damaged, the hex flats are rounded or corrosion prevents correct removal and refitting. Replace damaged hardware discovered during wiper-arm or motor service.

A loose or slipping arm also calls for inspection of the arm's splined connection and the motor spindle. A new nut will not repair worn splines, a seized arm joint or a failed motor. Confirm the cause before tightening hardware to address poor wiping.

Installation and service notes

Verify the assigned mounting position and original nut number. Support the arm during removal, inspect the mating surfaces and set its parked position according to the vehicle-specific procedure. Start the nut by hand and use the prescribed tightening specification without applying extra force to damaged threads.

Refit the protective cap where equipped, check clearance and verify wiping operation. Front and rear mounting hardware can differ, so vehicle fitment alone does not identify the correct nut for every arm.

Fitment

Confirm the original mounting position, production date where specified and hardware assignment before ordering.
