Front bumper bolt and nut question.
 
I removed my front bumper the other day and I'm in the process of cleaning up the bolts and nuts. I noticed the nuts have slots cut into the top side.

What is that sort of nut called? (I assume it's a locking feature of some sort).

Also, if I was to go back with regular nuts, could I just slip in a lock washer and get the same effect?

It's called a top lock nut or stop nut. A lock washer should work assuming it seats properly.

Thanks.

Now speaking of "seating properly" I noticed the flat washers that were on there had a pretty solid impression of a hexagon shoved into them. Do I need new flat washers when I put the bumper back on?

I'm just going to go back with a Teflon type lock nut on mine. By the way washers are about .17cents. I'd replace them. Either way but sure if there enough room for a Teflon type nut, but I'll cross that bridge when I get there

So that's a "stover nut" that came on the front bushing bolts!

I ended up just buying new zinc plated nuts, washers, and split washers.

HMM>....would I need like a grade 5 or grade 8 (stronger metal) nut though?

IMO, you're overthinking this. You're just bolting on a bumper. .02

Grade 5 is what was used.

Hmm. I may just use what I had on originally, maybe using a new flat washer and adding in a split washer.

Later, if I add the Luverne grill guard, I'll have to have 4 longer (than stock) carriage bolts. I am fearful to use grade 5 there as the grill guard may bend the frame if the bolts won't break off.

Damage that front bumper and your choice of mounting hardware will be the least of your concerns :lol:
