It is a M8 1.0 nut. I found out the hard way because all the hardware store has was a M8 1.25, so I bought it and the threads were way too coarse

what size can be the nuts holding the front wheel?
I am able to access a URL in Chrome 36 and IE8 but in Chrome 39 or 40 or Firefox 35 it throws the error:


  Unable to make a secure connection to the server.  This may be a
  problem with the server, or it may be requiring a client
  authentication certificate that you don't have.
  
  Error code: ERR_SSL_PROTOCOL_ERROR}. 


It seems that it is an issue related to the SSL certificate. How can I fix this?
