I only had a regular 32 mm 6 side socket available at home at the time. I then used my old halfords pro 12 sided socket and the bloody thing coped with it. Then I saw arronmorris on good ole landyzone was selling some sockets so I got a set off him. But the britpart driveshaft I fitted at the weekend had a 36mm nut! The only 36mm tool I have is a spanner which is no good for hub nuts. So I have been forced to use the old nut until I get a 36mm socket.
