I was wondering what size the bolts are to the rear bumper that go on the metal bar along the bottom of it. As i was trying to take them off every bolt broke off barely even trying.
Rear Bumper Bolts
- Thread starter Syris
- Start date
Those are hefty bolts...You must have some serious rust back there if you sheared off all four...
No the head will not do to match it up. Metric fasteners are a little different than standard US sizes.
Thread should be m10x1.25
I dont know the length.
And go with SS.

definitely go for ss, if you can try to drill out the bolt after the head has been snapped off. takes a hell of a long time but thats what i had to do for my fronts when replacing them with ss hardware. if you need the pitch, get a thread gauge and use that to check the thread pitch inside the holes.
take a cutting wheel and cut off any bit of the bolt that is protruding from the hole.
drill a 1/8" hold in the middle of the original hole with the old bolt stuck in there.
use SS self tapping bolts to remount your bumper and use the hole you just drilled to start the bolt. The self tapping bolt will make its own thread as its being drilled in

Or you can get a bolt extracting kit.
The one I have, depending on the diameter of the bolt, there are sized drill bits and slighlty larger knurled rod sections. You drill into the stuck threaded rod with the drill bit 1/8 to 1/4" deep. Then you insert the correct size rod into the hole (may need to hammer it in), there is a fitting that attaches to the free end of the rod so that a socket can be put on it, then you just use a ratchet and spin it out. Because of the texture on the rod, it bites into the hole you just made and spins with the stuck bolt pulling it out. Takes no more than 5 minutes. Obviously some broken bolts are in awkward places where a handheld drill can not fit.
