OVERVIEW
Original M8 x 45 hex-head fastening hardware
N-010-345-10 is a Genuine VW/Audi M8 x 45 hex-head bolt used at specific original fastening points. Its confirmed applications include the Mk3 VR6 center muffler hanger and the separate classic-vehicle locations identified in the fitment table.
Hardware selection depends on the actual joint, not simply the model name. The correct shank length and head form help preserve the intended assembly clearance and seating arrangement. This individual bolt does not include a hanger, bracket, washer or nut.
Technical details
- Complete factory number: N-010-345-10.
- Factory specification: M8 x 45 mm hex-head bolt.
- Design: External six-sided head with threaded shank; match the complete factory number and original mounting arrangement.
- Quantity supplied: one individual bolt.
The nominal M8 x 45 designation describes the fastening dimensions. No packaged shipping dimensions, weight, strength grade or unverified thread pitch are assigned.
Common reasons to replace
- Damaged threads or a bent shank found during component removal.
- Rounded hex-head flats that prevent secure engagement with the correct tool.
- A missing bolt or an incorrect substitute installed during an earlier repair.
When servicing an exhaust hanger, inspect the rubber support, bracket and surrounding hardware as well as the bolt. A new bolt alone cannot correct a torn mount, distorted bracket or damaged receiving thread.

Installation guidance
Support the component being serviced before removing its fastener. Start the correct bolt by hand, preserve the specified washers and spacers, and tighten according to the factory repair procedure for that exact joint.
Do not apply one universal torque value across exhaust, engine, steering and transmission applications. Check the completed joint for correct seating, clearance and component support.
