Running board bracket fasteners/hardware

[23RST]

Does anyone know a parts kit for attaching the points circled (see attached photo)? If anyone knows a thread pitch that would also help as I could put my own hardware together if needed.

I scooped up a pair of running boards & am in need of the fastening hardware that attach the brackets to the body.

If this goes work get back to me! I have few in my tool box and I can measure them.

Mine I put on this weekend. Mine are rough country HD2 step very similar to yours. And the original Silverado steps like your are an awesome step. Great look to them. Mine from roughy country leave no gap between cab and step, which I was going for. Let me know if I’m wrong on that size but I think that’s it.

Bolt is 11519388.  M8x1.25, 25mm length.  

 

Nut is 11561740.  This one is the right thread but slightly larger than the nuts that come in the boards new.  GM doesn't have a mounting hardware pack for any of the boards outside of a whole board package.

I put Rhino boards on mine. I had to buy the hardware in a separate package from the boards. Don't know if you can buy just the nuts and bolts, but given the specs you've received from others it should be a simple matter to pick some up. The truck's frame rails are pre-drilled and tapped already. Good luck!

Thanks all for the replies

 

I ordered this kit as it was cheaper than buying dealership stuff I didn't need. Of course none of the bolts match the threads on the truck....

Going to try those GM bolts and find some stainless washers from McMaster

22876958 is a kit with 8 each of those nuts and bolts

^^^and that sounds like what he'd need. 4 of the smaller and 4 of the larger per side, 16 total. The kit 23RST linked to had 32 bolts total.

where do the clips go? Body is threaded - just discard them?

[TrueBlue]

If that's the entire kit, where are the other 8 bolts. Mine only used 3 brackets on each side, yours has four. So there should be two sets of eight bolts. On mine one set took a 13mm and the other a 14mm wrench. Don't know the thread size and pitch but they're different for the upper and bottom holes.

Where is that nut/clip used? From what I see underneath my truck the bolts go directly into the body. I don't see anywhere or such clips to be placed.

I'm so sorry my brain has been mush lately.  I'm used to the last gen trucks that had those nuts that I thought the newer ones still use them.

 

Looks like these are different.  There is threaded inserts where bolts go into.
