Hi,
The screw hex head of item 375 is damaged/stripped . Anyone know the specs for this and where can I buy a replacement? And any idea how could I unscrew it ?
Hi AIA,
the correct specification is:
Mushroom head bolt M6 x 20 mm with 4 mm Allen key head, made of stainless steel.
Well-sorted DIY shops should be able to source it.
Alternative: front-axle-bolt-strida
I’d suggest you look for professional help regarding unscrewing, that can be a tricky task. Professionals will have the required tools already, namely screw retractors.
Hint: The original bolt was glued with thread locking compound, heat will help to loosen it (~ 200°C). Instead of a torch, you should use a temperature-controlled, electric heat-gun.
In worst case, you need to replace the front axle 238.

Also, you could send me the axle and I’ll try my best 
Cheers,
Chris

Hi Chris,
Thank you for your help! 
I managed to unscrew it now and I will buy another one with star shape instead of Hex.
This happened because I used the automatic screw driver for fastening the screws. I realized it is better to use torque wrench for the last rotations and should be slow + apply little pressure toward the screw.
I feel that this bike is like Lego for every piece there is a trick. Yesterday I removed the magnet by using the metal piece from the rear wheel … Then I needed to figure out how to release it … The magnet 
is so strong. Then I put the magnet in the wrong direction and it was impossible to take it out … I removed the brakes screws to remove the tire and the magnet then some washers fall down from the back… I thought the flat washeres should be in front …etc it took many hours 
Hi AIA,
fine to read that you managed that 
Naaah, not that wild…you need tricks also for other bikes…
Here’s the trick for the magnet btw…slide something with big mass (big hammer) sideways over the magnet - and then pull in direction of the axle - magnet will be attached to hammer 
Next time you’ll be much faster I bet
