Dropout screw / Tension Screw broken in frame
Hey guys,
Any thoughts on how I can get this out of the frame?Difficult to get to a shop right now, and I’m hoping since a bit of the screw is sticking out I can use something to twist/remove it. Thanks in advance for the help.

There is quite a bit sticking out, I personally would give it a good shot of WD-40 and then crank some vice-grips on hard, could even file a little bit flat for better grip while turning it.

My first attempt would be using a Dremel cutoff wheel to cut a slot in the end for a flat head screwdriver.
I also second the idea to use penetrating oil before putting a lot of force on the screw.

It appears that the rear facing end of the screw is bent. I would figure out a way to remove towards the rear if possible, using methods described above.

If you remove from the rear, you should first cut off the portion in the front that has a lot of boogered up threads.

I would use NATLOZ recommendation, but if the screw moves keep moving it front and back, more and more to clear out the threads in the frame. if it moves freely try and remove it to the front. If that hangs up, then screw it to the back, cut off the bit in the back and remove it to the front.

cutting a slot on the end as already suggested would be a good start. curious how they managed to get so badly bent? they aren't meant to hold the wheel, once the axle nut or bolt is torqued properly they should be backed off.

Carefully file it off with a rat-tail file. One could also use a mounted stone on a drill or die grinder. I have a little carbide burr that I use in the die grinder that would make that little bit go away.

Could you post a photo of this ? I have grinding stones for my Dremel tool, but they are too wide to fit inside a dropout.

Here you go. The one on the left is a 1/4" carbide burr that I use in my die grinder. It would make very short work of the bolt. The little grinding stones would work, but would require patience.

Hmmm. I think I’d have a difficult time holding that carbide burr steady enough to avoid slipping and damaging the dropout. But that’s just little old me.
