inazone Posted May 27, 2017 Share Posted May 27, 2017 Anyone know what the steel tensile strength is for the standard toyota wheel studs? For example are the studs 12.9 grade? Link to comment Share on other sites More sharing options...
Dnk Posted May 27, 2017 Share Posted May 27, 2017 12.9 grade steel means that a component manufactured from this grade of steel has 12X100 N/mm^2 tensile strength Link to comment Share on other sites More sharing options...
inazone Posted May 27, 2017 Author Share Posted May 27, 2017 Thanks Dnk, do you know if the studs are 12.9 grade? Link to comment Share on other sites More sharing options...
Dnk Posted May 27, 2017 Share Posted May 27, 2017 (edited) No idea what grade Toyotas studs are, ARP's wheel stud tensile strength is listed at 200,000 psi 200000 psi = 1378.951458636 newton/millimeter² Edited May 27, 2017 by Dnk (see edit history) Link to comment Share on other sites More sharing options...
pedrosixfour Posted May 27, 2017 Share Posted May 27, 2017 I would very much doubt they are over 10.9, possibly only 8.8 as that would be perfectly sufficient for the tightening torque they're supposed to endure. Link to comment Share on other sites More sharing options...

inazone Posted May 27, 2017 Author Share Posted May 27, 2017 Need to know so I can check what the standard torque is for an M12 1.5 thread. Link to comment Share on other sites More sharing options...
