is Mild Steel as Axle Nut is low torque value.... fork pinch bolts do the work and I have actually run without a nut fer 1200kms..... oops - me bad? have had 20 cut.... 5 spoken for..... tag dimension from flat of nut void (giggle!) to bottom edge of tag = 25mm. You want me to weld some more length on?..... suggest you drill a hole in yer substrate (tyre lever) and have puddle welded..... neat!
