Don't even attempt to undo this with a allen key spanner you must use a socket type one.

make sure you clean out any cack from the head tap the socket in so its in all the way then undo with a ratchet or bar.

Worst case if you have rounded the head you could cut through the bolt then try and remove the remains or replace with a s/h one. There is a chance volvo still sell the clamps
