C300: C300mkii - Helmet bolt allen key size?

[analog_addict]

I have a C300mkii with the standard helmet that has two bolts to hold it on to the body.

Does anyone know what size allen key is needed for these? I've tried every imperial and metric allen key I have and nothing fits.

Thanks

Maybe these...the manual mentions them when mounting/attaching the included accessories.

Thanks but it's not the bolts I'm after. It's the allen key size for the two that hold the original helmet on.

What is the size of the hex socket?

You're not talking about this? [Sorry if I'm completely overlooking something.]

Thanks, I've purchased a 1/4" allen key from Amazon. Fingers crossed it works.

As someone who had learned the hard way, going back and forth to the hardware store more than once for slightly different sizes of nuts, bolts, wrenches or screws, it would be best to just get a full set of Allen keys if you don't currently own them.

Save yourself the trouble of guessing. You can get a full set of metric and imperial for $9.
