What size nut is on an Icon AAL kit?

I bought this kit

I noticed a nut and washer was missing from a U bolt when I was doing a rear brake job. Yes I torqued them to spec. No I didn't use thread locker. Picture of said nut



Can you please direct me to finding a single Icon nut and washer? Or what thread size/etc to buy a replacement? I don't want to drive with a missing U bolt nut Thanks

 

OK. I found the u bolt kit on its own. Can I buy just a washer and nut? Does it have to be specific nut since it is a suspension part or can I go to the hardware store?

Not sure you will find just a nut and washer available for sale individually. Since Ubolts are considered one time use it’s probably worth replacing the ubolt. Hardware store nut and washer would probably work as a temporary fix but not something I would trust long term.

 

Update

Icon is sending me an individual washer and nut after I called them and gave them what part # I installed.
