Wingnuts 

Author Steve Griffith

The sheer variety and type of wingnuts - in alloy, steel,  bronze and even plastic - never ceases to amaze me. Some very practical, some quite fanciful and elaborate, often incorporating the maker's name or initials, or even an imitation wing design. Fanciful designs seem to have been a French speciality. This was clearly an area where there was never standardisation of design, although most quality wingnuts incorporated a serrated washer to ensure both a good grip and that it would still be easy to undo. Wingnuts declined in use with the rise of the modern quick release, their heyday was the 30’s to 50’s. I note from an internet search they are still made today and companies such as Pashley fit them to their ‘retro’ bikes.

Wingnuts do add a bit of style to an older machine; however, I do recommend that you check before setting off that you can undo them. Use ones with the serrated washer and ensure it is moving freely.The Huret bronze ones are unlikely to break although they can bend. There is nothing worse than being stuck by the road side with a broken wingnut!!!

The table below seeks to summarise the fruits of my research (mainly rummaging through grubby boxes at jumbles and checking bikes on VCC runs). NB. Quite a few wingnuts have no maker's name and are difficult to identify but I am still trying…

3. GB
4. Constrictor
5. Sturmey

I am looking to compile a database of wingnuts, so any new examples please send to me, if possible with images. I know there are many more out there.
