No, there is no clamping pressure on the splines. Note that there is a circumferential groove in the splined post. The set screw passes in to this groove and holds the arm on to the spline that way, not by clamping on to the splines. So long as the set screw does not break off, or back out, the arm will be fastened securely to the spline. Here is a close up that will let you see the groove.
