Hawk 250 rear axle nut pitch and size urgent

[Rocksyoursocks99]

Ig I didn't torque it down all the way and lost the nut and just need a replacement what is the exact size and pitch or a nut that will work thank you urgent

Can you pull the axle and take it to Ace Hardware? Possibly Lowes or Home depot, but Ace would be the better bet IMO.

Besides properly torquing, recommend using blue Loctite too.
