There is no risk of spinning the strut shaft with this tool. This is only around $20 and it includes an extension socket for the rear strut tightening through that tiny hole. I wasted money on an electric impact wrench for 3x the price of this. Of course you will need a metric hex key to hold the shaft in place as well. Just tighten till it feels solid. Main point of the torque spec I think is to prevent over-tightening the nut. This is hard do to with this because the spring will twist before you end up over-tightening. If you dont have harbor tools the tool you want is "go through socket" 17 mm 14 mm
