!!NEED HELP!! Over tighted pedal nut

[pym19109]

Hi guys,
I just removed my pedal to install Cusco gas pedal. While I'm putting everything back, It's quite small space for turn the wrench so I keep turn it because I can't feel the tight and accidentally I over tighted the upper bolt. It's broke into piece like the pictures below.


Any suggestion to fix it?

Oof that’s a tricky one.

You could try and knock what’s left of the stud out and then see if you can bond a new one in there?

You could also drill it out and slide a nut in from the backside, then thread a piece of threaded rod into the nut.

You could also drill it out, install a rivnut, and then use a bolt or threaded rod in the rivnut.

Hard to tell from the pictures, but you may be able to get a rivnut in there that will work.

It's amazing how applicable your signature is to this thread.

lol it's there for me as much as anyone. I have broken so much stuff in my time "learning."

Thanks for the suggestions.

Will rivnut fits in side tiny space in the back of bracket?
or just weld a stud in will it work?

Rivnuts are installed from the front side with a special tool, or using a bolt and nut. The hole that you have may be too big though for one so you will have to check/measure.

I don’t have a solution, but for small things like this I like to take an extension and the 10mm socket to use as a compact screw driver.

I do that all the time even though I have a set of nut drivers

All day long. Less tools to switch out. Better balance between grip and ability to spin on or off.

Nut drivers have their place but socket+extension is way more versatile. Some extensions are knurled for just that reason.

not really helping at all but just for future reference most stuff "IN" the car are usually only around 20-25 n/m so pretty much a light hand tight. except stuff that's bolted to the frame of the car like seatbelt or seats...

20-25nm is boarder line too tight for those. 6mm mid grade fastener should only be like 8ftlb which is like 10-11nm.

After I did a search for similar problems, there is not much information for me. I will try to hammer the stamped stud out first (maybe with a extractor also) and wish the god of subie is kind to me XD. if not, cutting the leftover piece and drill will be my only option but this will be a difficult job for sure with a little room there and yes like many of you said "ONLY HAND TIGHT ANYTHING INSIDE THE CAR"

It's not so much inside-versus-outside. Everyone has over-torqued fasteners. Everyone has cross-threaded fasteners. The lesson here is to understand that it's natural to want to get in there an really cinch it down tightly so it doesn't come loose. We must learn to fight that urge.

For newb friends I've had under my wing, I put old screws in the vise and had them turn nuts slowly until they strip. Materials vary. Aluminum is super tricky because the threads yield - begin to strip - more gradually than steel.

Use a torque wrench.

That one will be a bitch. Cut the weld stud down flat. Drill & tap to 6x1.0 mm thread. You might need a bottom tap to finish the job but it's doable. Cut a hex head cap screw to the correct length and clean the threads until it starts nicely.
