Rare 8 sided nuts

[Elvishaslanded]

I doimg an 1100 Uno,s frint wheelbearings and the bearings retaining nuts are 8 sided.
Its an very old car and the hub treads for the new nuts not good anymore from age and rust (which i cleaned off) but still needed some torque to tighten the new nuts. Bit of a flimsy nut and vannot be chisseled tight which is in anyway a bad idea

Made a tool as per attached photos for this job and worked well.

Nice work! Show us more of the project. We love these stories and pictures that go with them.
Welcome to the site and you will enjoy it.

How'd you make the tool?

I would have wanted a regular nut to go back on there... hopefully you put some anti seize on them!

Nice solution to your problem, @Elvishaslanded.

What size is the octagonal nut?

It's pretty common to use octagonal nuts for "safety" knockoff spinners on wire wheels where the spinners with "ears" aren't allowed. Those are, I think 2¾ inches (70 mm). The normal knockoff wrench wouldn't work on a recessed nut, however, even if it were the right size.

I have cut a few of those slugging wrenches on the plasma - I always try with the big water pump pliers first but, I don't try as hard as I used to.

Heavy trucks use 8sided nuts for front wheel bearing preload adjustment,

And OTC makes the socket. I’m sure others do, also. What car are you working on?
