They are also known as ZXN bolts. Spline drive is very different from the others. The hardware doesn't have "points" at all, instead have "teeth" with a squared-off cross section. Think like the splines on an axle shaft, or u-joint yoke/flange.
In some low-torque applications, spline, triple-square and double-hex can "cheat" with each other acceptable. I've even cheated an inverted torx with a fractional box end wrench before without damaging anything. However the problems start with rusty, and high torque applications. You will damage or ruin the fastener if you use the incorrect type of socket or driver bit.
You need the proper socket. There is also limited room around the fastner and I have seen both reg and impact sockets vary slightly in diameter.
