Going to bring it to the body shop tomorrow. Basically the fix in my mind is simply drill through the bolt stub with a new one and forget about hood struts and be done with it. I’ll let the shop do it. They’re always great. If they say nothing can be done cut my losses. Also the stability of the hood is fine. It doesn’t shake or rattle and seems just as tight and sturdy with 3 as it was with 4 bolts. It really isn’t a “big” deal it’s just an annoyance and a little ugly when the hoods open. Ironic that I wanted to change the hood prop due to it being ugly now I’m back to it with this gross thing now. Hopefully the shop takes care of it nice and easy and I’ll just forget about it. Lol.

I almost feel for what that was it should have been torque'd to 17 inch/pound not foot/pounds

Hey guys, I'm having the same issue as OP but with the trunk studs. I don't know if OP's solution would work on the trunk as there's no stud left.

Exact same thing just happened to me- trunk as well. Howd you end up getting this fixed? Same ways that were mentioned previously?

Go to a welder. It usually can be fixed with a tig weld.

10-12 ft/lbs should be more than enough for those small studs. 20 seems a bit excessive.

More like inch pounds. Realistically hand tight is way more than enough.

That seems a little bit too loose.

The studs look like 8mm studs. 6mm studs on my dirtbike are 7-8ft lbs so that's where I came up with the 10-12 ft/lbs.

I doubt hand tight is enough to stop the hood / trunk from slipping due to the leverage it puts on those mounting points.

It's going to depend on what metric bolt class the stud happens to be. There are general torque guidelines for this, and the following image was posted 3 years ago with reference to the hood fasteners (should at least be good for general guidance).

But it's still going to be best to check what Ford's own spec is.

Ford spec for 2015-2017 is in Post #18. I wouldn't go that tight, probably 12-13 ft-lbs even thought the spec is 17 ft-lbs.

Could be the spec is different for the 2018+ ... someone needs to check the Ford service manual for 2018+ models.

Here is the torque wrench setting. I took a shot after the bolt broke just see if I had it set incorrectly.

Sorry about your bolt breaking, but easy fix like the previous guy said.
NOW: A piece of advice, get a inch pound torque wrench for the little bolts. Believe me it will save you more head aches. Good luck

Ever better pick where & when a torque wrench is needed.
Hood struts seems to be not one. The material a fastener is made of is in play. Never mention but is a factor. The first picture of this thread clearly shows a bolt not up to the task.

Generally speaking not all, most automotive mechanical installs. Require one to break out the torque wrench.

Posting a reference chart some my find handy .

It's not the torque value it's the length of the wrench and the leverage that snapped the bolt
