    Prop shafts nuts and bolts 2012 Patrol Y61

    In re. to my post about the slip joint locations, it is now time to reinstall the shafts. I am looking at replacing the existing nuts and bolts. Can anyone recommend where to get them? Nissan is of course the obvious choice, but usually the most expensive. Boltmasters were no help whatsoever.

    The nuts are flanged, but any nut and bolt shop will have them, theres nothing special about the thread. How come Boltmasters were no help? Did you take a sample in to them?

    weel just had a crawl under my patrol and have the bolt in my hand 12mm fine thread flanged head and nut 17mm across the flat
    bolt fixes 37mm underside head to end of thread and.... shank 12.5mmdia 17mm long ..
    So there is no bolt head markings ! cant get to the hardness tester its busy here .. but don't think a standard bolt will work well .

    Yeah just check a pic of the genuine bolt from the parts catalogue. yep tiny step in it. Hence me not remembering. I wouldn't bother with new bolts personally unless they are rooted. Bit of loctite on the threads and away you go.

    Yes, took in a sample, but they don't stock grade 8 M12 with flange and shank. The bolts look ok, but the nuts are shot. Does anyone know a good online supplier?

    Thanks for your trouble. I did find the specifications on the net and it is grade 8.
