S13 Seat bolt threads? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

The rear left bolt hole in my S13 is stripped out. Does anyone know the thread pitch, so I can get a tap and re-thread it?

It's this one, if you didn't understand:

M12 x 1.25 or M10 x 1.25, not positive

I Googled it and the results are all mixed.
This says M10x1.25, but this says 12x1.25....

KiLLeR2001 · 03-13-2013, 08:16 PM

M10 x 1.25.

I just pulled one off my car to verify.

Thank you! So this will work to re-thread it, correct?

Killer is correct.

A tap won't fix it if the threads are stripped though. Cross-threaded, yes. Stripped, no. Maybe a helicoil or weld a new nut to the bottom of the floor.

Well, it's weird, because I can thread the bolt by hand about 1/4" into the hole, then it just stops. But if I get a socket to thread it in, then it goes in, albeit a little tough.

Cheapest option is to buy (from me off course)

If stripped beyond repair!!!

Option 1 - buy "weld nuts" the flat ones, so all you do is drill out the hole and then you weld the nut in place with new threads and all!!! , this of course required a welder. ( for me this is the easiest solution )
Option 2- go a size bigger bolt size which is unlikely in this situation I might think.

But taps are expensive! Also, heli coil would wont work for this situation

Do yourself a favor and invest in a tap and die set. I have a $60 one from harbor freight that works fairly well. I have collected other sizes as time went on. If you plan on doing significant work on your car then you will eventually need this. Plus, it comes with thread gauges so you won't have to ask people on the internet what type of bolt you need.

For 80 bucks or so u can get a craftsman, lifetime warranty

The Dude · 03-14-2013, 12:56 PM

The Harbor Freight set also has a lifetime warranty. I haven't seen the Craftsman set, but I imagine that it is slightly better quality.

I'm not as big of a fan of Craftsman these days as I think the quality of their stuff has gone down while the price has kept climbing. The drive sheared off my Craftsman torque wrench a while ago and the wouldn't take it back because it requires calibration (which, apparently, makes it not a "hand tool" and not subject to their lifetime warranty).

Sorry for the rant. Seriously, go pick up a tap and die set though.

Craftsman won't warranty ANY of my 3/8" ot 1/2" drive sockets anymore because they've been used on an impact gun. They're getting to be rather shitty about things.
