What advantage is there for torx vs. this pentalobe screw?
- regularfry 16y agoMy guess is that you'll get less tool head wear with pentalobe, but torx are in more peoples' toolboxes.
- bradleyland 16y agoI'm no engineer, but here's my guess: At these tiny sizes torx bits end up with some very thin material at the tips of the star pattern. The pentalobe has one fewer tips and the curves are inverse, resulting in more meterial in the bit and less in the fastener head. That makes for a more durable tool at the expense of the fastener durability. These screws weren't intended for frequent removal though, so it's a good trade-off from a tooling perspective.
