Hey I was wondering if anyone has replaced any of the e torx bolts with regular ones. I am going to be swapping transmissions in my car and the bolts I pulled for the junkyard transmission are kinda beat up and rusty. The ones on the car now look even worse. So anyone know if swapping to a standard head bolt would work? If so anybody have the sizes you need to do it?

Torx-head bolts are used because they can take much more torque than standard hex-head bolts. The star shaped head is much stronger. Torx bolts also fit perfectly onto their corresponding sockets. Hex always has a certain degree of slop between the head and the socket/wrench.
Since you need a few feet of extensions and possibly a u-joint to install/pull the transmission, the risk of stripping the bolts is much higher if you're not careful. I personally would not swap to hex. Get new torx bolts if your current ones are beat up.1989 325i Lachssilber Sedan

They are only a few more dollars to buy new external Torx bolts than to use regular hex heads. It's very difficult to get a hex socket on the bolts if separating the engine/trans in the car.Comment

A complete set of new e-torx bolts for the transmission isn't going to "break the bank". If plain hex head bolts would have been satisfactory, BMW would have used them as e-torx cost a touch more.The car makes it possible, but the driver makes it happen.
