Drilling frame help

Installing sidestep on my 110 and I have to drill 2 holes on the frame to mount two outriggers... Question should I use rivnuts or drill and use a regular bolt? Drill through both sides of frame or not necessary?
Basically need help how I should mount this without causing any potential damage to frame down the road.
Thanks in advance. Eddie

Rivnuts are not for anything structural or load bearing. Nut and bolts are what you need.

Measure thrice, drill once. Use a punch to set your hole locations before drilling. Drill the properly sized hole for your bolts.

Should I drill completely through both sides of the frame?

If you don't can you get a wrench to grab the nut?

Not sure what you mean or asking? See pics above...that is exactly where I have to drill. Those bolds are something else Tcase mounts so not using those.

If you drill thru the frame where the bracket holes are can you hold the nut while you tighten the bolt or do you have to go thru the entire frame to hold the nut? You could also weld on some threaded rod and then have the nut outside of the frame saving you from drilling any holes what so ever. That is what I would do myself if it was on my truck.

Dave was being facetious.
What he meant was if you only drill one side of the frame and you don't drill the other side, you can't bolt it though because there is no way to put on a nut much less hold it with a wrench from the inside of the frame which is sealed.
You'll need to drill it all the way through so you can put the bolt through, put a nut on the inside of the frame rail (because the bolt is sticking out) and hold it with a wrench while you tighten the bolt head on the outside of the frame rail.
Be sure and use some large fender style washers.

Damn, I had to actually look up what "facetious" meant and I assure you I wasn't being facetious with my question or statement regarding nut grabbing. If you don't have access to the inner part of the frame then you absolutely have to drill all the way thru or go with the threaded rod welded to the frame approach.

After checking the chance that I misspelled one word for another with a different meaning, are you sure that you were not being facetious instead of facetious?

Ah now I understand the question. No, I cannot grab onto anything because it is a boxed frame totally enclosed with no access except by drilling through in both sides. Dave I like your suggestion on welding a bolt but unfortunately I don't have one so drilling through sounds like the only option. I didn't know if a self tapping screw would be strong enough.

Some prior owner tried to install one of those crossbars on mine as if it was some kind of giant sheet metal screw mounting into the hollow frame surface with no nut on the other side, of course. Epic fail. Nice to see some legit options to repair it before I lose track of the parts. I like the weld-on scheme. Thanks!

Hmmm, maybe that's what mine actually was. Whatever it was, it didn't hold up.

I wasn't being deliberately flippant or inappropriate. Funny how a typed message looses its meaning where a verbal conversation would have been so easy to understand.
Keep your hands out of your pants and get a spanner on the 6 sided bolt tightening device that threads onto the bolt and as Robert mentioned, use some nice sized fender washers.

Well, the steps sort of look like fold-down dust pans & they have a black ribbed tread with an all-black LR oval logo in the center. The end of the crossbar supporting the remaining step on that side of the rig has a bolt or screw running thru it with a hex head that fits a 13mm wrench & it definitely doesn't go all the way thru the frame. Did your steps come with anything like self-tapping screws that a 13mm would fit & aren't long enough to go all the way thru the frame?

It could be that mine hasn't held up bc of the need to remove & re-remove it in order to service & re-service the fuel pump over the years, which is how I became acquainted with it in the first place.

You have the fold down side steps. I have the long fixed, tubular sidesteps. My steps came with no hardware or instructions.

Thanks Dave and Rob and others that helped me with my questions.
Ed

ps this thread has been a fun to read

I wonder if perhaps you have it set up wrong. Usually thise things borrow an existing bolt hole. In any event, if you can't use an existing hole, install a riv nut in the side of the chassis. A fine thread sheet metal screw would work too but the riv nut would be a little better. The only stress on those fasteners will be from vibration or if you whack the step on a rock or tree stump.
