Same comments as above - the blunt end makes future working around the screws much less hazardous as there is less probability of drawing blood. The blunt end works well with the Tinnerman U-Clips.

These type B screws not having the sharp point is I think a real plus just from a not so easily getting scratched when later working around them. Over time, I am replacing all my type A with the type B as they are more user friendly.

I got some of the #4 x 3/8 and they work perfectly for interior trim panels on my Cessna 172. They are just the right size and shape to hold all those plastic panels together.
