seatbelt bolts
ewanspence - 24/5/02 at 09:34 AM

The bolts from the Sierra belts were 12mm fine thread metrics bolts, I don't have any of the correct nuts (oohh err missus). Can I use 10mm 8.8 grade (same as original except 2mm less dia) with nylocs nuts. I can access both sides of the mountings so I don't think I need to make the nuts captive?

The inspector may inspect the bolts so best use the originals and get some right nuts

I Think they've got to be 11mm or 11/16th's, grade 8.8 min.

Cheers

This is all in the SVA manual Ewan. If you havnt got a copy this far into the build you are corting disaster. They do need to be about 11+ mm as Chris says.

They also need to be - described something like - 'indestructable' mounted. If the tester undoes the bolt, then it must screw back in without anything gripping the nut from the other side.

Thanks
folks,

I do have a manual but it is the worst written book I have every hd the delight in using.

If only we had an electronic version that was easily searchable!! (I know we used to)

for a set of regulations, it reads surprisingly well!


Try the section on seat belts......

Wasn't me who started this thread but I'm at this point so I'll ask anyway... are you guys saying I need to weld nuts to my seat belt 'triangles'?

Cheers, Chris

I read somewhere that so long as you can get to both sides of the nut/bold to allow securing it was ok.

I am in doubt now so will probably just weld anyway.

I would have thought nylocs were better than welded no-nylocs - can't come loose as easily!!

ChrisW - 27/5/02 at 11:23 PM

That's what I was thinking.. and I wouldn't want to weld nylocks!

it says in the manual that they must be 'indestructable' and not need a tool from both sides.

Most cars I have taken belts out of (make that all) have a captive or welded nut.

Actually (just to confuse everyone) we used 10mm bolts... but we have 4 point harnesses, so maybe the load distributed over 4 points is no worse than 3 x 11mm bolts? Either way, the SVA inspector never queried them.

The only size I've seen is 7/16" 20 thread for belts.

I have a 6 point setup from LUKE.

I've got the sabelt 4 point harness,this has the 7/16" bolts as well.
I have threaded tube welded in for the upper and lower mounting points.
The bolts from SABELT are not long enough to come out the other side of the threaded tube,so i'm putting longer bolts in and nylocs on the other side.
Hopefully this will be OK for the SVA.
