Picked up a set of used JK side steps from another member here. He didn't have the hardware to go with them. I just need to know what OEM uses for harware. Looks like metric (10MM head nuts) on the side flanges and a 7/16" bolt (diam.) fits through the flat plate holes, but not sure about washers or spacers that might be need.

Any help appreciated. Got my 2.5" Rancho lift on and the 33's, got to have the step for the kids to get in!

I just installed some Rubi Rails and this is the hardware I picked up from Autozone.
U-Nut x4 M8x1.25
Screw and washer x4 M8x1.25x30
Would need 6 of each if you have a 4door. I would think this is what would work for underneath, then just get some small screws/washers/nuts for the pinch seam holes.

Just did this for my 4 door and had to take a few trips to the hardware store. MOPAR has a list of hardware somewhere but I found the short list on a forum. I used x12 M6-1.00 nuts and locking washers for the vertical flange mounts and x6 M8-1.25-30.00 bolts for the undercarriage mounts. I didn't actually need the u nuts as my undercarriage came outfitted with threaded nuts as a part of the mounting weldment. One things that the MOPAR list neglected to mention is that if you're not buying specific MOPAR part numbers, you may need large flat washers to keep the nuts, bolts and locking washers from slipping through the slots/bolt holes. So here was my final list:

for 4 door...
(all stainless steel parts)
x12 M6-1.00 nylon nuts
x12 M6 slotted locking washers
x12 M6 flat washers
x6 M8-1.25-30.00 hex-head bolts
x6 M8 slotted locking washers
x6 M8 flat washers (3/4"-1" diameter)

if needed
x6 U Nuts M8

for 2 door...
x8 for all M6 hardware
x4 for all M8 hardware

1-2 hours of install time

Hope this helps!

BTW Don't mean to seem like I'm stepping on the Kolector's toes. His info is succinct and likely backed by more experience than mine! When looking around, I had a hard time finding a complete bill of materials, so I thought I'd share what I've learned to provide a full list for someone else in need.

Not taken that way at all, I found ones that worked, not necessarily the 100% correct ones. They are still on the JK and tight to this day, so I guess they are good to go! I think its mainly the bolts matching up to the clips more so than the size of them.
