Shinjuku Posted December 27, 2011 Share Posted December 27, 2011 Can someone tell me the bolt diameter and threads per inch/diameter of the wheel bolts of the Z? Want to know what locking bolts to buy? Thanks Shinjuku Quote Link to comment Share on other sites More sharing options...
nzr350z Posted December 28, 2011 Share Posted December 28, 2011 Might be worthwhile removing 1 of the bolts and comparing it to something in shop you are looking.Locking bolts are standard just wondering why you need new ones? Quote Link to comment Share on other sites More sharing options...
roadtrip Posted December 28, 2011 Share Posted December 28, 2011 The studs on a Zed have a thread which is M12x1.25, i.e. 12mm (approx. 0.47 inch) diameter and 1.25mm pitch (20.32 threads per inch). You will also need to know the seat that is suitable for your wheels, I believe that the 350Z 18" standard and Rays alloys use a 60° taper seat nut whereas the 370Z Rays 19" use a flat seat nut. You'll probably want to check but from what I can work out you'll want Nissan part number 999H1-A7009 or McGard 24154 for the taper seat, Nissan 999W2-JT000 or McGard 21153 for the flat seat. I'm sure someone will be along soon to correct me if I've got any of that wrong! Quote Link to comment Share on other sites More sharing options...
