Mystery wheel nuts. Help please

[Javelin301]

Just bought a Dawes Sa

Just bought a Dawes Sardar. It has these funny wheel nuts. I assumed they were hex sockets but no-5 sided recesses. Do I need a special tool? Any tips?

 

[DCLane]

It looks like someone has put an Allen key skewer in there for security. An Allen key should undo them, allowing you to replace them with quick-release skewers if preferred.

Nope, those are 5 sided holes. Try the TranzX skewer set - you'll have to buy the skewers too to get the tool.

These security nuts are a pain unless you have the tool. You might be able to use a bodge with a standard Allen key and a thin blade screwdriver. Looks like someone might have already tried that judging by your second pic. Then just junk them

Probs a grind a slot in them to be able to use a flat head jobbie if you don’t have the locknut

Bash in a torx bit then undoo and throw away

Thanks folks. They look nice but sounds like they'll have to go

Try and get some spray lube in on em as they can rust up.

Cut a few off over the years there a pain if not greased go gently

That’s not even on the extensive Wikipedia ‘List of Screw Drives’!

I got a spare penta key when my TransX one broke. Ask at bike shop.

 

[Javelin301]

Penta key is the magic phrase that unlocks the mystery. Thanks

I don't think I'm allowed to post up screwing while driving a moped.....

They are Trans X skewers.
