    To minimize damage to the hex corners (especially if it's a small hex size -- e.g., 7 or 8 mm), use a closed 6-point driving form for breaking it open -- box wrench or deep socket (you might have to if the hex corners are already a little damaged ;)).

    It could be 7 mm -- the 328 SPC drawing implies a small hex size, and its brother, the TR, uses 7 mm at the rear. Not only did I have to buy a 6-point box 7mm wrench from Sears for my TR, had to grind about 1 mm off of the side of the box to get proper engagement -- good luck.
