my snapon torque angle gauge is 1/2" drive...i torqued my arp main studs to 15 lb ft, went to go use the torque angle gauge, and i don't have any ******* 1/2" sockets for the studs!!!!! coulda sworn i did but they're all 3/8".

is it ok to leave them torqued to 15lb ft overnight, or maybe a few days? i already aligned the thrust bearing so i don't want to have to redo all those bolts.

what would you guys do?

 

yes its ok
just go back and recheck them but nothing is going to happen
arp main studs shouldnt need the angle gauge just torqueing to the listed spec.

 

Exactly! Just TQ them down to ARP recomended specs as they don't recomend the Torque Angle method. Here is the link.
