Going to have to disagree i would say that a spline socket would be needed here.
First 2 pics are spline male and female and third and forth picture are torx

As bob says buy the torx i have only ever seen spine bolts holding heads down and have always used a torx socket to get it out.
All moden car are now torx also look out for torx male sockets with little holes in the middle theses are safe torx.
