P500 Skid Plate Install - Rivnuts or Self Tapping?

[john790]

Your way past to getting that bolt out.Move your new bolt to a different location slighty.Use a rivnut into frame somewhere just recess the skid plate some.No one will know but you and me I WILL NOT TELL.

That occurred to me as well.

Boogered threaded mount. Don't know if there's enough to re-thread for larger bolt?

Shots of sheared bolt, sheared extractor.

These are both driver's side, main frame

For the forward location (the sheared bolt spot) I should be able to install a +nut or two instead.

For the rear location (boogered threads), that's at a spot where two pieces of the skid come together so I need something there.
Can I rethread that spot? With what, a tap? One that goes into a drill, or one with a T-handle thingy?
Can it be drilled out hollow to accept a +nut?
Other thoughts?

TIA!

If you can't drill out the old one, maybe you can use a spot weld drill bit. It's basically a mini hole saw but.......might work 🤷‍♂️. If not and it were me, I'd run a self tappers right beside the broken bolt.

A nearby substitute anchor is indeed the plan for that spot. but with a +nut or two.

I just need a plan for the spot with bad threads. I need to use that spot. I don't know if I can re-thread it or not.
Do I have to go bigger; from M6 to M8? Or should I try to rethread with M6? Or try to ream it out with 3/8"?

 

[futzin]

Are the threads just in the metal of the framing material, or is there an insert of some kind?

You'll probably need to go up in size.

Just the thickness of the metal

Update: I got the sheared bolt spot drilled out, ready for a +nut. Slightly off center; the pilot bits wandered away from the fused mess but it should work.

I'll try an M8 tap in the other spot.

Thanks!

( . . . worst thread ever . . . )

No metric taps at the local Homey Despot. So I drilled it out to 3/8". Plus nuts now in both locations.

Much ado about very little, I know.

No more Critter work until Monday. Hopefully get the skid pieces back on then.

Certainly appreciate the help!!

Skids reattached, all good.

What a boring thread.

Thanx




Seriously, a big 'thank you' to @lee for the plus nut / x nut idea. Seems more secure than the rivnuts. I only heard one of them snap from overtightening.

Documenting is another of not-my-fortes. Those seem to be piling up . . .
