Seat belt bolt threat size?

8002 Views 13 Replies 5 Participants Last post by  Ed Jarvis
So me and my buddy were installing the rear seat back in and the front edge of the bolt cross threaded. Bolt will need to be replaced which I'm going to get from a dealership. Does anyone know the thread size/pattern so I can tap the hole out to clean out any misthreads (rear seat, lower bolt next to the door).

Get a triangular file and file away the burs on the existing bolt. You should be good to go from there:

Ooo, good info; that will help with using the exsisting bolt rather than having to buy the entire seatbelt assembly again. But I also need to know the tap so I can clean out the threads in the body.
The best thing that I would do, short of relying on the dealer, is to go to a Home Depot or Lowes type of place and go to the isle with all of the screws, bolts, and nuts. They should have a chart that you can check the thread pitch and size. I f in doubt ask for help from the person that handles that area. I have found, at least in Mansfield, TX, them to be helpful in a positive way. They may also have the required tap on hand.
The 60/40 rear seat assembly requires a quantity of 6 hex head bolts that are 10 x 1.25mm tighten to 47 newton meters or 35 lbf-ft

The left and right hand outside rear seat belt assemblies use a single 7/16-20 UNF hex head bolt tighten to 32 newton meters or 24 lbf-ft

The center seat belt buckle assembly uses two 8 x 1.25mm hex head bolts tighten to 22 newton meters or 16 lbf-ft

It's Wayne's fault!! It's his service manual..........:p
I dont suppose Wayne would mind sharing the thread details about the Front seat anchor bolts as well, would he?:D

Threads for the window seat belt are as good as new. I used one of my precision files on the bolt that i had and it worked great as well. Thanks for the tips. I was gonna cut the bolt off because technically it doesn't need to be as long as it is from a mechanical point of view (majority of the applied load on bolt is in the first 3 threads).
Let me know when you find the threads for the bolts that hold the front seats down.

The front seat assembly requires a quantity of 4 Torx head bolts that are 10 x 1.25mm tighten to 47 newton meters or 35 lbf-ft (Use a T45 Torx Bit)

There are some more bolts below the Torx bolts. I believe they need a 14 mm socket to remove.

I just answered my own question. The bolts I'm looking at are 10mmx1.25 threading.
Just searched the forum and wasn't able to find anything on this so I wrote a new thread about it. Before I hit "post", I did a quick Google search and this thread came up! Just ordered the taps and hope that will fix my rear seat thread issue!

Thanks!
