Do you really take the time to line up both nuts so a 12pt. will fit over both? Wouldn't a ratcheting box wrench on the lower nut be easier? or even maybe a stud remover?
I only use 12pt. sockets on 12pt. bolts, a 12pt. socket dosen't have the same contact area as a 6pt, making the chances of rounding the nut much greater. I have 6 and 12 pt. wrenches too but the 12pt. get used more because they fit bolts in areas with limited access better. if it's a high torque situation I'll use a 6pt.
I have all that equipment.
I agree on using a ratcheting wrench on the lower nut when there is room to swing the wrench, and the stud turns fairly easy....
On stubborn studs, I torque them back and forth as they are removed. I favor a small breaker bar so I do not have to mess around with the reverse on a rachet... Once the stud is comming easy, I would use a ratchet.
In close quarters; I have gone in with a crowfoot socket and an extension to hold that lower nut while I tighten the top nut with a socket and a second extension.. If the two nuts tighten together, and are in a 30 degree pattern, there is no reason not to use a 12 point socket that fits over both nuts to back that stud out... If the two nuts tighten together with even flats, that is good, but it don't always happen that way.. Do yourself a favor; add a supply of grade 8 nuts and their metric counterparts to your stud removal equipment...
I have Proto stud removers in both 1/2" and 3/4" drives. Those bad boys have the wedges that come in from the sides and can be reversed to turn either direction..they will get some serious studs out, but need more room. My Craftsman 3/8" and 1/2" drive bolt/nut removers grip in counter clockwise direction only, so no torquing back and forth with the Craftsman sets....
If the studs have good threads, the jam nuts hopefully work ok for stud removal. If the stud has to be reused, The jam nuts are the winner..
Were we talking about sockets a while ago??
