OVERVIEW
Genuine VW/Audi flat washer, part number N-011-670-26. This washer provides a bearing surface between the specified fastener and its mating component. Correct washer geometry helps distribute the fastener load across the intended contact area and preserves the assembly's original hardware arrangement.
Technical details
- Original part number: N-011-670-26 / N01167026.
- Published nominal dimensions: 8.4 x 24 x 2 mm — 8.4 mm center opening, 24 mm outside diameter and 2 mm thickness.
- Flat metal hardware washer, supplied individually as pictured.
- Bolts, nuts, springs, sleeves and the mounted component are not included.
- Application depends on the exact mounting point. Match the original part number and washer dimensions rather than assuming every fastener on the vehicle uses this washer.
- This is a mounting washer; it is not described as a fluid-sealing ring or a substitute for a separately specified gasket.
Common reasons to replace
Replace a washer that is missing after disassembly, bent, deeply corroded, worn around its center opening or damaged at its bearing surface. Hardware that no longer sits flat can alter contact at the mounting point or leave the assembled fastener stack incorrect.
Inspect the associated bolt, nut and mounting surface at the same time. If a bracket, support, lamp mounting point or component housing is cracked or distorted, a new washer alone will not restore the attachment. Where the assembly contains a spring or sleeve, verify those separately instead of using extra washers to compensate for damaged parts.
Installation and service notes
Follow the factory procedure for the specific assembly. Support any component that will be released, note the order of the original hardware and clean the mating contact surfaces without removing sound material.
Install the prescribed washer in its original position and use the specified fastener. Replace any companion hardware that the service procedure identifies as single-use. Apply the correct assembly torque; a washer's dimensions do not determine the fastener's tightening specification.
After reassembly, check component alignment and retention. For lamp hardware, check the lamp's seating and required adjustment. For exhaust hardware, allow the system to cool before work, support the pipes and check clearance and the correct spring/sleeve arrangement.
