How to remove seat rail bolt after you've stripped it - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

I'm not sure how many people have stripped the seat rail bolts, but I'm one of them. The metal is soft, they use an e10 hex stud, and they're unbelievably tight.

Anyways, if you did strip it, hopefully this saves you 2 hours figuring out a way to get it out.

Start by drilling a small divot into the bolt head surround

Next, take a hole punch and place the tip into the pilot hole at an angle which would cause the bolt to spin counter clockwise

Start tapping with a hammer and eventually it will come loose

Replace the stud with a new one, they're about 7$ from a dealer

Here's a pic of the bolt afterwards. You can see the pilot hole that I used to give the center punch some grip. As you can see, I tried a bunch of other methods but this one ended up taking like 2 minutes

Unless you cut up the seat rails you will not find a good replacement is issue. I went through same gig and went to mother of all bolt suppliers and couldn't find anything where you could actually fit a socket in with conventional head bolt. If you do get lucky and find something that does work that you can get at please share.

Actually I did find a proper bolt at Parts Source. When I say proper bolt, I mean right length, head size and thread. However I don't remember the part number off hand. They would not fit in my case with my GT-Spec seat rail supports because the built in washer diameter was slightly too big, which could easily been ground down to size if I really wanted to be creative. But I ended up using the proper tools in advance including a breaker bar to remove the oem bolts and just re-used them

Surely a socket head cap screw would fit in place of one of those, wouldn't it?

OHMYGOD thank you so much. I've spent my whole damn afternoon swearing at one screw. It got to the point where Ace Hardware employees were telling me it was a lost cuase. You're amazing. I hope something amazing happens to you today.

lol^ I stripped one of mine as well but an impact gun at a shop saved my life. I replaced the oem bolts with diff bolts all together. It was difficult to say the least tightening the new ones with limited room. Using planted seat bracket and universal rails on bride gias II.

I tried everything and then realized my buddy has a mig welder.

Good solution.

For those that do not have access to a welder, but air tools. Attach a cutting/grinding burr, grind down the head of the E10 bolt and extract.

I replaced all of my seat studs with normal bolts long ago, the stock hex bolts can go to hell.

The posting which described how to remove the seat rail bolts was right on for me. It was exactly the problem I was having and the solution described was perfect. Thanks for the posting!

My case is similar. The previous owner had mangled the bolt heads trying to get them out and gave up. I bought a Craftsman E10 Torx socket off of eBay for 3.99 with shipping included. I put the socket on a long extension with my ratchet. I beat on my ratchet with a hammer while applying force to the bolt head. Even though there was next to nothing left of the bolt head, the hammering force and the what was left at the bottom of the bolt head was enough to break it free. To look at it you would have never thought it was possible, but it worked. So have confidence...don't give up...and beat on it while applying torque. You might be pleasantly surprised.

By the way, does anyone have the part # for the stock bolts? Thanks in advance.
