6 Mudguard stay bolts and nuts 4.34 mm D8

Secure Fender Strut Attachment for Classic Bicycle Restorations

Finding period-correct hardware with accurate threading is one of the most common challenges when restoring vintage mudguards. This set of six pre-owned mudguard stay bolts and nuts features a 4.34 mm bolt diameter (D8 specification) designed specifically for classic fender mounts. These original parts ensure a secure grip, preventing the rattles and alignment issues common with modern generic hardware.

Because these are authentic vintage components, they may show minor cosmetic signs of use or long-term storage, such as light surface wear or micro-scratches, which do not compromise their mechanical integrity. No major structural damage or stripped threads are present on these fasteners.

Perfect Fit for Vintage Touring Bikes

This hardware set is essential for completing the fender assembly on classic builds. If you are rebuilding a vintage French or European touring bike, proper stay bolts are crucial for stability over rough roads. To ensure your entire fender setup is period-correct, you can pair this hardware with our Steel Front & Rear 39mm Mudguards for 700c Touring Bike, or if your project requires a wider profile, consider the Steel Mudguards 39mm for 700c Touring Bike.
