M10x28 bolt

[DWBOX2000]

I took a m10x28 bolt off my car and then couldn’t get back in. Is it possible that I could strip the threads putting it in by hand? The seat bolt was a bear to get out and had lock tight on it. I’m usually really careful so just curious if something I could even do without a socket wrench. I had a socket on with N extender I was turning by hand. Thanks

If it's Japanese, maybe so. I seem to strip those regularly, especially on Hondas. They use soft material for bolts.

If there was loctite on the bolt threads there is probably some on the female threads. Try a sharp L pic running in the threads and see if anything is scraped out. I think it's impossible to strip M10 threads by hand or were you the governor of CA some time ago?

Get yourself a thread chaser kit. I use it ll the time, very handy to have on hand.

Thanks all. Porsche seat bolt. Very frustrating, get seat out but can’t get electrical connectors off immobilizer. Figure I’ll wait on project until next winter (water proof box). Go to put seat in, bolt won’t go in. The threads on the bolt look a little nasty. Will try a tap and die set.

editnever mind- just saw your post.

Can you move the seat over enough to just put the bolts in by themselves without undoing the electrical thingee?

Are these the four seat bolts holding the seat to the chassis?

I guess it doesn't really matter what it is. Just pull whatever it's supposed to attach off, and focus on just making the bolt go into the threading.

For example- the seat, pull out the seat and run the bolts in by hand seatless. Probably some loctite still in there. If the seat in place is messing up the angle to get the threads to engage, loosen the other bolts until you can get a good angle. Thread chaser good, but you can probably just get it started by hand and use a hand socket wrench and not mess anything up. My latest favorite is using 1/4 inch drive sockets on stuff like this, or for larger sockets use a 1/4 wrench with an adapter to go to 3/8 drive socket. The small wrenches spin nice in tight spaces and don't have enough torque to really strip something easily, since the wrenches are so small. It keeps you honest.

Thanks for the advice. I’ll try again tomorrow. Bolt threads look a bit cross so work on those.
I’ll get it in.

I'll be doing this myself at some point. Good luck and thanks for the heads up on a possible hiccup!

The seats are often not completely square. So the last bolt can be a PITA. Leaky's advice on trying it without the seats in place is good so you know the bolts and threads are good. If good try again and wrestle the seat into place so the bolt goes in completely at 90 degrees. I do know what you mean. I had the same thing swapping the seats in the SC.

Thank you. I’ll certainly watch.
